Polydesmide Et Craspedosomides Cavernicoles Nouveaux De France Et Du Maroc (Myriapoda - Diplopoda), Jean Paul Mauriès
International Journal of Speleology
This is a description of the affinities and biogeographic significance of three new cavernicolous species of Diplopoda from France and Morocco. One species apparently belongs to the Polydesmida (family Paradoxosomidae) and the other two to Craspedosomida (families Caratosphydae and Chordeumidae).
1) Eviulisoma abadi n.sp. is distinguished from other species of this genus by total depigmentation, by the characters of the gonopodial orifice and the male gonopods, by the low number of segments (19) and by its geographic isolation (Morocco) and ecology (Kef Aziza cave). This justifies the establishment of a new sub-genus, Jeekelosoma. The other species of this genus …

The Anatomy And Histology Of The Alimentary Tract Of The Blind Catfish Horaglanis Krishnai Menon, T. V. Anna Mercy, N. Krishna Pillai
International Journal of Speleology
H. krishnai is a blind catfish inhabiting the dug-out wells at Kottavam Kerala, South India. Studies on the alimentary tract of the fish show that, the alimentary tract, though typically teleostean, shows several adaptive modifications. The bulbous stomach helps in storing food which is helpful in an environment chronically deficient in food. The ileo-rectal sphincter helps in retaining the digested food in the intestine for a long duration to facilitate maximum absorption. This is very helpful as the intestine is short. The liver is well developed.
Thermodynamics And Kinetics Of Aqueous Solution Of Liquid Hydrocarbon Mixtures (Solutes, Petroleum), David Robert. Burris
Thermodynamics And Kinetics Of Aqueous Solution Of Liquid Hydrocarbon Mixtures (Solutes, Petroleum), David Robert. Burris
Dissertations, Theses, and Masters Projects
Two-phase systems of a liquid hydrocarbon mixture, containing medium molecular weight (C(,7)-C(,12)) aromatic and aliphatic hydrocarbons, and water were examined in both equilibrium and kinetic experiments. Knowledge of the aqueous solution behavior of liquid hydrocarbon mixtures is of importance in determining the fate of hydrocarbon components in such systems of an environmental or geologic nature. Solute concentrations were determined by solvent extraction followed by gas chromatography. The equilibrium solute concentration for a given component i (C(,i)) is related to the pure compound solubility (C(,i)('o)), mole fraction of component i in the hydrocarbon phase (x(,i(h))) and the activity coefficient of component …
Changes In Forest Soils Following Clearcutting Of Pine Forests In The Ouachita Mountains Of Arkansas, Harlan R. Stoin, Bajuri Bin Kadmin, Lyell F. Thompson
Changes In Forest Soils Following Clearcutting Of Pine Forests In The Ouachita Mountains Of Arkansas, Harlan R. Stoin, Bajuri Bin Kadmin, Lyell F. Thompson
Journal of the Arkansas Academy of Science
Soil characteristics of the mineral surface soil (0-6 cm) on three small watersheds in the Ouachita Mountains of Arkansas from which the pine forests have been clearcut, crushed, and burned for site preparation were studied for the first two years following clearcutting and compared to soils from adjacent uncut pine forest watersheds. Following clearcutting and burning, soil pH was generally higher than in uncut forest soils. The greatest pH differences occurred within several months of burning and generally decreased through the end of the second year. Soil organic matter content was lower immediately following clearcutting and burning and increased to …
The Inapplicability Of The Concept Of The "Sidney Gravel" To The Ogallala Group (Late Tertiary) In Part Of Southern Banner County, Nebraska, Robert F. Diffendal Jr.
The Inapplicability Of The Concept Of The "Sidney Gravel" To The Ogallala Group (Late Tertiary) In Part Of Southern Banner County, Nebraska, Robert F. Diffendal Jr.
School of Natural Resources: Faculty Publications
A series of geologic maps of counties in western Nebraska was prepared for the Nebraska Geological Survey during the mid-1 930s. These maps showed the distribution of rock units of Tertiary age including a formation designated as the “Sidney.” The Sidney Gravel was described as a widespread sheetlike complex of channel deposits, but with small areas where it is not developed. In southern Banner County, Nebraska, there are several channels filled with sand and gravel that were mapped as Sidney in this series. Recently one of these channel fills has been observed to cut across the other. The fills are …

Cenozoic Paleogeography Of Western Nebraska, James B. Swinehart, Vernon F. Souders, Harold M. Degraw, Robert F. Diffendal Jr.
Robert F. Diffendal, Jr., Publications
The Cenozoic strata of western Nebraska are an extensive sequence of continental deposits that extend eastward from the Hartville, Laramie, and Front Range uplifts and southeast from the Black Hills. The oldest Cenozoic sediments (Chadron Formation, White River Group) are Early Oligocene alluvial valley fills. Subsequent to filling of these drainages and continuing for about the next 7 million years, landscape development in western Nebraska was dominated by eolian deposition of tremendous volumes of rhyolitic volcanic ash derived from western eruptions. A plain of low relief, with only an occasional narrow drainage heading in the western highlands, was maintained during …

Current, Erosional And Depositional Patterns At A River Confluence And Bend In The Nottawasaga River, Angus, Ontario, Gregory Robert Brooks
Current, Erosional And Depositional Patterns At A River Confluence And Bend In The Nottawasaga River, Angus, Ontario, Gregory Robert Brooks
Theses and Dissertations (Comprehensive)
At a bend and confluence of the Nottawasaga River, sixty-four measurements of flow velocities were recorded at points along vertical profiles regularly spaced across a series of cross-sections. From the summarization of the data into a ‘three dimensional’ diagram, the current velocity patterns in the river reach were evident.
As observed at low discharge levels, the low speeds and directional uniformity of the flow in the Nottawasaga River entering the study reach suggests that the observed asymmetrical channel the study reach suggests that the observed asymmetrical channel was a remnant of higher discharge levels. On the other hand, in the …
Metamorphism And Migmatization Of Metasediments In The Precambrian English River Subprovince, Western Ontario, Rodney M. Baumann
Metamorphism And Migmatization Of Metasediments In The Precambrian English River Subprovince, Western Ontario, Rodney M. Baumann
Theses and Dissertations
Metasediments of the Precambrian English River subprovince, a subdivision of the Superior province, are conspicuously migmatized by 'bands of light-colored, igneous-appearing material. The metasediments them.selves consist of alternating layers of pelite and wacke lithologies, which represent original mudstones and graywackes respectively. Their deposition is thought to represent subaqueous turbidity flows.
For the metasediments of the study area, a 250 square kilometer portion of the English River subprovince, metamorphic grade increases southward from the English River subprovince's northern border. Two isograds have been mapped: the disappearance of muscovite and the disappearance of stable sillimanite. Geothermometry studies are consistent with the trend …
Middle And Late Wisconsinan (Pleistocene) Insect Assemblages From Illinois, Kristine D. Carter
Middle And Late Wisconsinan (Pleistocene) Insect Assemblages From Illinois, Kristine D. Carter
Theses and Dissertations
Two highly organic sediment sequences from central and western Illinois (the Athens North Quarry and Biggsville sites, respectively) of Middle and Late Wisconsinan age were studied to gain knowledge about the environment and climate of this area during the time immediately prior to the maximum extent of the last glaciation. Paleoenvironmental and paleoclimatic inferences are based principally upon knowledge of the habitat preferences and geographic distributions of extant species of beetles that are represented as fossils. These data are supplemented by information from sedimentological and taphonomic studies and from previously published palynological and plant-macrofossil studies.
The Athens North Quarry site …
Petrology Of The Beulah-Zap Lignite Bed, Sentinel Butte Formation (Paleocene), Mercer County, North Dakota, David R. Kleesattel
Petrology Of The Beulah-Zap Lignite Bed, Sentinel Butte Formation (Paleocene), Mercer County, North Dakota, David R. Kleesattel
Theses and Dissertations
The Beulah-Zap lignite bed is one of several economically important lignites in the Sentinel Butte Formation (Paleocene). This lignite occurs as a subsurface unit in the Knife River Basin of Mercer and I Oliver counties of North Dakota. The Beulah-Zap lignite is a heterogeneous carbonaceous rock unit composed of megascopic and microscopic I components, which are lithotypes and macerals, respectively. Relationships between the maceral contents of the lithotypes follow patterns similar to those of bituminous coals. Coal petrology, the study of maceral and lithotype occurrence and I distribution, was applied to determine: 1) mode of coalification, and 2) depositional environment …
Depositional Environments And Diagenesis Of Carbonates And Associated Evaporites, Frobisher-Alida Interval, Madison Group (Mississippian), Williston Basin, Northwestern North Dakota, Thomas J. Obelenus

Metamorphism In The Eastern Lac Seul Region Of The English River Subprovince, Ontario, Steve J. Chipera
Metamorphism In The Eastern Lac Seul Region Of The English River Subprovince, Ontario, Steve J. Chipera
Theses and Dissertations
The English River subprovince of the Superior Province, Canada, is a linear, east-west trending high-grade metamorphic belt which extends from Lake Winnipeg in the west, to the James Bay lowlands in the east. It is composed of two prominent lithologic domains: a northern sedimentary gneiss-migmatite domain, and a southern plutonic domain. The northern domain consists primarily of alternating migmatized layers of garnet-biotite "wacke" and garnet-cordierite-biotite "pelitic" metasediments. The southern domain is composed mainly of intermediate granitic to trondhjemitic plutons. Bordering to the north and south are the lower grade Uchi and Wabigoon greenstone belts. Metamorphism and migmatization occurred during the …
Nouvelles Données Morphologiques Et Caryologie Du Triclade Hypogé Pyrénéen Dendrocoelum Lescherae, Nicole Gourbault
Nouvelles Données Morphologiques Et Caryologie Du Triclade Hypogé Pyrénéen Dendrocoelum Lescherae, Nicole Gourbault
International Journal of Speleology
The study of a new strain of the hypogeous Tricladida Dendrocoelum lescherae has demonstrated the very low anatomical variability of this species. The chromosome complement was found to be 2n = 32; measurements of somatic mitoses have shown that these elements are metacentric; the gametocytes possess 16 bivalents. Number and morphology of the chromosomes are similar within the subgenus Dendrocoelides.
Two New Genera Of Cave-Dwelling Millipedes (Diplopoda), With Remarks On The Millipede Fauna Of West Caucasian Caves, Sergei I. Golovatch
Two New Genera Of Cave-Dwelling Millipedes (Diplopoda), With Remarks On The Millipede Fauna Of West Caucasian Caves, Sergei I. Golovatch
International Journal of Speleology
Two new genera and species of the Diplopoda from Caucasian caves are described: troglobitic Caucasodesmus inexpectatus n.g., n.sp. (family Macrosternodesmidae) from a cave in North Osetia, North Caucasus, and troglophilic Ratcheuma excorne n.g., n.sp. (family Antroleucosomatidae) from a cave in Racha, Georgia, Transcaucasia. Millipedes of the western Caucasian cavernicolous fauna are reviewed as regards their distribution, relationship with caves and zoogeographical connections.
Morphological Clines In Reduced Areas. The Case Of Henrotius Jordai (Reitter), Cave-Dwelling Beetle From Majorca Island, Xavier Bellés
Morphological Clines In Reduced Areas. The Case Of Henrotius Jordai (Reitter), Cave-Dwelling Beetle From Majorca Island, Xavier Bellés
International Journal of Speleology
The present paper shows a statistically significant correlation between the geographical latitude and the morphological variation of the pronotum of Henrotius jordai (Reitter) (Col. Caraboidea), cave-dwelling beetle from Majorca island, after studying the linear and curvilinear regression between these two variables. The existence of specimens situated at different heights of the regression lines leads to the conclusion that morphological variation is clinal. The phenomenon of “semi-isolation” to which the studied populations are subjected, because of their cavernicolous character, allows to explain the existence of a cline in such a restricted area as that occupied by this beetle (ca. 500 Km …

Geochemistry Of Alteration And Mineralization Of The Wind River Gold Prospect, Skamania County, Washington, Krista I. Mcgowan
Dissertations and Theses
The Wind River gold prospect is located in TSN, R7E of Skamania County, Washington, and is an epithermal gold-quartz vein system hosted in volcanic rocks of the Ohanapecosh Formation, a late Eocene to middle Oligocene unit of calcalkaline chemical composition. Andesitic pyroclastic rocks of the Ohanapecosh Formation are the host of mineralization in the study area, and form the lowest of several stratigraphic subunits. These pyroclastic rocks are overlain by two sequences of lava flows which cap the ridges and are folded by an anticlinal warp over the length of Paradise Ridge, plunging gently to the southeast. Toward the west, …
Geology And Geochemistry Of Hydrothermal Alteration, Eastern Portion Of The North Santiam Mining Area, J. Michael Pollock
Geology And Geochemistry Of Hydrothermal Alteration, Eastern Portion Of The North Santiam Mining Area, J. Michael Pollock
Dissertations and Theses
The Ruth Mine is a base-metal vein deposit near the eastern margin of a reported porphyry copper deposit in the Western Cascade Range in Oregon. Uplift of the Western Cascade Range has resulted in a deeply dissected terrain in which more than a kilometer of the stratigraphy overlying the porphyry-style mineralization is preserved and exposed. The stratigraphic units, which are middle Tertiary in age, have been given arbitrary letter designations beginning with the lowest unit (Unit A) through the uppermost unit (Unit D).
Structure And Evolution Of The Horse Heaven Hills In South-Central Washington, Michael Curtis Hagood
Structure And Evolution Of The Horse Heaven Hills In South-Central Washington, Michael Curtis Hagood
Dissertations and Theses
The Horse Heaven Hills uplift in south-central Washington consists of distinct northwest and northeast trends which merge in the lower Yakima Valley. The northwest trend is adjacent to and parallels the Rattlesnake-Wallula alignment (RAW; a part of the Olympic-Wallowa lineament). The northwest trend and northeast trend consist of aligned or en echelon anticlines and monoclines whose axes are generally oriented in the direction of the trend. At the intersection, folds in the northeast trend plunge onto and are terminated by folds of the northwest trend.

Late Quaternary Environmental And Climatic History Of The Southern Chilean Lake Region Interpreted From Coleopteran (Beetle) Assemblages, John W. Hoganson
Theses and Dissertations
A diverse Coleoptera fauna of 462 species in 48 families was collected from 41 locations in the Parque Nacional de Puyehue and adjacent parts of the Lake Region of southern Chile. The sample locations ranged from rain forest habitats at sea-level to Andean tundra habitats at 1500 m msl. Cluster analysis of a Dice similarity coefficient matrix revealed a broad pattern of bioassociations within the large data base, Boundaries between the bioassociations correspond largely with those of the major vegetation zones implying that the distribution of the fauna is strongly influenced by the distribution of plants. Evidence from fossils indicates …
Petrology Of The Sentinel Butte Formation (Paleocene), North Dakota, Nels F. Forsman
Petrology Of The Sentinel Butte Formation (Paleocene), North Dakota, Nels F. Forsman
Theses and Dissertations
Sedimentary materials of the Sentinel Butte Formation have been petrographically examined using optical and scanning electron micro scope/microprobe techniques. The formation consists of fine-grained materials which generally are classified mineralogically as volcanic litharenites or feldspathic litharenites. Most rock units in the formation are siltstones and mudstones. Multiple source rock types, including volcanic, metamorphic, and sedimentary, are represented by mineralogic constituents, but volcanic rock fragments are most abundant. Petrographic distinctions between basal and uppermost sandstone units suggest that a change in sediment supply took place near the end of Sentinel Butte time. Authigenic cement development appears concentrated in more porous and …
Draining A Saline Seep, W J. Burdass
Draining A Saline Seep, W J. Burdass
Journal of the Department of Agriculture, Western Australia, Series 4
Sub-surface drains have dried out a salty seep on farm land in the Katanning district. Capeweed and clovers are now growing on more than three-quarters of the land that was previously bare or carried only patchy sea barley grass.
The drains are still running water after five years. The salt content of the surface soil has been reduced markedly and the salt content of the effluent water is decreasing.
However, to complete the reclamation, further drains will be necessary. Both existing and any new drains will have to be flushed periodically because blockages of pipes cause problems.
A Quantitative Analysis Of Shoreline Erosion Processes, Lake Sakakawea, North Dakota, Mark D. Millsop
A Quantitative Analysis Of Shoreline Erosion Processes, Lake Sakakawea, North Dakota, Mark D. Millsop
Theses and Dissertations
Shoreline erosion is a problem at Lake Sakakawea and Lake Audubon, North Dakota. Land is lost, water quality is adversely affected, and reservoir storage capacity is decreased.
Instrumentation of the eastern shores of both lakes began in 1983 to quantify bank erosion by process (e.g., wave erosion, rainsplash and runoff, and frost-thaw failure). Other data gathered included: pool level fluctuations; wind velocity, direction, and duration; precipita tion; soil moisture; frost penetration; freeze-thaw cycles; and geology (e.g., texture, clay mineralogy and structure).
The magnitude of shoreline erosion is highly variable, especially within Lake Sakakawea. For the interval of May 1983 through …

The Geology And Hydrocarbon Potential Of The Dawson Bay Formation Carbonate Unit (Middle Devonian), Williston Basin, North Dakota, Wayne R. Pound
Theses and Dissertations
The Middle Devonian Dawson Bay Formation carbonate unit is present in the subsurface of North Dakota except where truncated by post-depositional erosion. The carbonate unit thickens from the erosional limit to a maximum thickness of 47.5 m (156 ft.) in Renville County and reaches a maximum depth of 3798 m (12, 432 ft.) below the surface in McKenzie County. In North Dakota, a submarine hardground separates the carbonate unit from the underlying “Second Red Bed member” of the Dawson Bay Formation. The upper contact with the Souris River Formation is conformable except in those areas where the Dawson Bay Formation …
Geochemistry And Petrology Of The Lake Vermilion Formation, Ely Greenstone Belt, Northeastern Minnesota, Scott E. Robinson
Geochemistry And Petrology Of The Lake Vermilion Formation, Ely Greenstone Belt, Northeastern Minnesota, Scott E. Robinson
Theses and Dissertations
Alteration in the Lake Vermilion Formation took place at low water/rock ratios. Calculations using the method of Grescens (1967) indicate that the amount of open-system elemental exchange was slight. During secondary alteration, Ca, Na, K, Rb, Sr, and Ba were very mobile; Mg and Fe were less mobile; Si, Al, Ti, Zr, Y, and Ni were slightly mobile. Chemically the rocks resemble modern spilites and keratophyres.
The dacites and basalts are depleted in Ti, Zr, and Y relative to Tertiary igneous rocks of similar composition. The Lake Vermilion Formation basalts display a volcanic arc basalt trend of constant Ti02 with …
