Regional Hydrothermal Alteration Of The Leadville Limestone (Mississippian) Of Central Colorado, L. V. Benson

United States Geological Survey: Staff Publications

Massive metallic-sulfide deposits were implaced in the Leadville Limestone {Mississippian) of Central Colorado less than 70 million years ago. The thermal fluids which precipitated ore at Gilman, Colorado have regionally altered the Leadville Limestone. The sequence of alteration began with the recrystallization of limestone to a dark medium~grained dolomite containing a homogeneous distribution of Fe. This Was followed by partial recrystallization of the medium-grained dolomite to coarse-clear dolomite which contains an inhomogeneous distribution of Fe. The resulting banded rock is known as "zebra rock" . Precipitation of Si0 2 (jasperoid) occurred next. The jaspe=oid formed prior to the deposition of …

The Fauna And Paleoecology Of The Charleston Quarry Shale, James Karl Gilliam

Masters Theses

The fauna and paleoecology of a late-Pennsylvanian shale contained in the Livingston Limestone of eastern Illinois is here defined. The name, Charleston quarry shale, is informally used for this shale in the area of the Charleston Stone Company quarry, northeast of Charleston, Illinois (SEC. 32, T. 13N., R. 10E., Coles Co.).

The fauna consists mostly of bryozoans, brachiopods and crinoids distributed throughout three distinct zones in the Charleston quarry shale. This fauna inhabited an offshore quiet bottom area in a shallow, warm, marine epicontinental sea which covered the area in the late-Pennsylvanian geologic period. The depth of water above the …

Ragni Delle Filippine, 1. Un Nuovo Althepus Cavernicolo Dell'isola Di Mindanao (Araneae, Ochyroceratidae), Paolo Marcello Brignoli

International Journal of Speleology

Althepus noonadanae n.sp. is described (female; male unknown; loc. typ.: Latuan Cave, Curuan district, Mindanao, Philippines); it can be distinguished from the other known species by the morphology of the chelicerae and of the female genitalia. It is not related to any of the very few described species. A key for the female Althepus is given.

A New Cavernicolous Species Of The Pseudoscorpion Genus Roncus L. Koch, 1873 (Neobisiidae, Pseudoscorpiones) From The Balkan Peninsula, Božidar P. M. Ćurčić

International Journal of Speleology

Roncus (Parablothrus) pljakici, a new species of cave living pseudoscorpions, is described from the cave ‘Pecina u selu Vrelo’ on Mt. Stara Planina, East Serbia. The problem of its taxonomic position in the subgenus is discussed. The new species is the first representative of Parablothrus to be found in Serbia. It seems possible that R. (P.) pljakici represents an endemic species, specialized for a cavernicolous way of living. The analogies of this and other species of the subgenus point to some similar phenomena which occur in other genera of Balkan false scorpions (Ćurčić 1972). In all these cases, a …

Xlix Contribution To The Knowledge Of The Amphipoda. On Three Niphargus Species (Fam. Gammaridae) From The Balkans, Gordan S. Karaman

International Journal of Speleology

Three Niphargus species from the Balkans are studied. Niphargus adbiptus, n. sp. is described from Ravanica cave in Serbia. Niphargus stygius ravanicanus S. Kar. 1943 from the same cave (Ravanica) is redescribed. N. valachicus Dobr. Man. 1933, is newly recorded from Bulgaria (Devnja).

Description Du Mâle De Mexistenasellus Parzefalli (Crustacea Isopoda Asellota Cavernicole Du Mexique) Et Observations Sur Cette Espèce, Guy Magniez

International Journal of Speleology

Description of the male of the Mexican cavernicolous Stenasellid Mexistenasellus parzefalli Magniez, 1972, from Huizache Cave, San-Luis Potosi State, Mexico. In the female with a brood pouch, the coxopodit of the maxilliped contains two provisional, oostegit-like plates, whereas the ovigerous female of european Stenasellids have only the inner one. This temporary sexual female character is known in other Isopods, such as the cavernicolous Caecosphaeroma burgundum Dollfus.

Les Populations Naturelles De Stanasellus Virei Dollfus (Crustacé Asellote Troglobie), Guy Magniez

International Journal of Speleology

Many cavernicolous and phreatic localities are known for the species Stenasellus virei. Some of these, which harbor a rather abundant population have been studied for several years. The endemic populations from permanent waters of some fossil karstic systems seem to have an abnormal composition. They include especially large individuals (juvenile stages being rare). They differ from the phreatic populations, which exhibit a normal distribution in size groups with a normal percentage of juveniles. These differences in the structure of populations may result from physical differences between the habitat in free waters of caves and in phreatic water, and from …

Feeding Efficiency In The Cave Salamander Haideotriton Wallacei, Stewart B. Peck

International Journal of Speleology

Selection for efficiency in food capture may be a dominant influence in the evolutionary biology of predaceous cave animals. A sample of 8 Haideotriton wallacei from a natural population contained 21 feeding boluses in their digestive tracts. Fourteen of these boluses contained food, demonstrating success in at least 67% of the feeding attempts.

Stratigraphic Comparison Of The Precambrian Wyman And Johnnie Formations In The Western Great Basin, California, Johnnie Nathan Moore

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Precambrian Johnnie Formation in the Death Valley area and to the south is separable into two facies. The southern facies contains six distinct members: the transitional, quartzite, lower carbonate-bearing, siltstone, upper carbonate-bearing, and Rainstorm members. Dolomite, quartzite, and mudstone characterize the southern facies, as does the presence of the Johnnie oolite. To the north the Johnnie oolite pinches out and the amount of mudstone in the formation increases. The dominantly mudstone northern facies contains local gray limestone lenses closely similar to limestone in the Wyman Formation in the White-Inyo Mountains. Generally outcrops of the northern facies of the Johnnie …

Seismic Refraction Study Of Post-Pliocene Stratigraphy, Dismal Swamp, Virginia, William Brian Fraser

OES Theses and Dissertations

This study examines Pliocene-Pleistocene lithostratigraphy and the Yorktown unconformity within the Dismal Swamp by means of remote sensing analysis, Wyrobek-Gardner seismic refraction profiling and split-spoon coring. Pre-Sangamon fluvial/tidal channel deposits are not present and the Yorktown unconformity dips irregularly southeastward at 0.35 meters/kilometer (2 feet/mile) from a high at 4 meters above sea level to a low of -1 meter (+12 to -2 ft) below sea level. The marker velocity for the Yorktown Formation is 1600 mps (5250 fps) and regression of seismic depths of the Yorktown Formation with corresponding split-spoon depths yields a high correlation. Short line upper layer …

Branchiobdellids (Annelida: Clitellata) From Some Eastern North American Caves, With Descriptions Of New Species Of The Genus Cambarincola, Perry C. Holt

International Journal of Speleology

Branchiobdellids are found as epizoites on crustaceans of the orders Isopoda and Decapoda (cambarine crayfishes) in caves of eastern North America. Species that may be considered as troglobites, since they are not known from epigean waters, appear to be confirmed to truly troglobitic isopods and possibly a few troglobitic crayfishes from Florida and the Tennessee-Kentucky Highland Rim cave belt. The majority of the records of branchiobdellids from caves are of representatives of common epigean forms epizootic un crayfishes. Cross-referenced lists of branchiobdellids, their hosts and cave localities are presented. Some of the new species described are apparently troglobitic or troglophilic, …

Feeding Behavior Of The Salamander Gyrinophilus Porphyriticus In Caves, David C. Culver

International Journal of Speleology

The feeding responses of salamander larvae (Gyrinophilus porphyriticus) from caves in the Powell Valley in Virginia were investigated in the laboratory. The larvae locate prey by mechanoreception and capture the prey by a rapid sucking action, much like cave-limited salamanders do. Feeding success is greater with the isopod Asellus recurvatus (about 90 per cent) than with the amphipod Crangonyx antennatus (about 50 per cent), and this largely accounts for the higher frequency of A. recurvatus taken in choice experiments. G. porphyriticus readily ingested the unfamiliar isopod Lirceus usdagalun, but it took four weeks before it was digested …

Ii Popolamento Di Ragni Nelle Grotte Tropicali (Araneae), Paolo Marcello Brignoli

International Journal of Speleology

The so called “tropical” caves (most of which are also geographically “tropical”) are distinguished from the “temperate” caves by the much larger trophic resources. Spiders are common in both kinds of caves, but the groups present in one kind are mostly absent in the other (notwithstanding that many families are distributed over at least one temperate and one tropical region). As in all temperate caves more or less the same groups of spiders can be found, so the tropical caves have a typical spider fauna, composed of different groups (often also more than those present in the temperate caves). In …

Stato Attuale Delle Conoscenze Sugli Histeridae Ipogei, Vincenzo Vomero

International Journal of Speleology

The author makes some considerations on troglobitic and endogeous world Histeridae. All these species present extreme reduction of eyes or are completely blind; all are wingless and only one is brachipterous. The Histeridae described here belong to the following genera: Speleacritus Jeannel and Spelaeabraeus Moro (Abraeinae), Sardulus Patrizi, Bacanius Le Conte, Troglobacanius Vomero and Geoculus Wenzel. (Dendrophilinae, Bacanius group). Finally some considerations on troglophylic and guanobitic Histeridae are made, reporting the recent discovery of a new genus and of some new species belonging to guanobitic biocoenosis of Mexican tropical caves.

Redescription Of Centromerus Bulgarianus (Drensky 1931) And Centromerus Lakatnikensis (Drensky 1931), (Araneae, Linyphiidae), Ch. Deltshev

International Journal of Speleology

The type specimens (lectotypes) of Centromerus bulgarianus and C. lakatnikensis, preserved in the collection of the Zoological Institut — BAN, Sofia, are redescribed. The redescription is necessary, because the original description is superficial and the drawings are inexact. Moreover, the male of C. lakatnikensis was unknown.

Temperature Preference Responses Of Some Aquatic, Cave-Adapted Crustaceans From Central Texas And Northeastern México, William R. Elliott, Robert W. Mitchell

International Journal of Speleology

The temperature preference responses of five species of troglobite crustaceans were studied in a 15°-30°C gradient. Stygonectes hadenoecus, S. russelli and Asellus reddelli had no discernible temperature preferenda. Speocirolana bolivari had a weak preference for 20-30°C. Cirolanides texensis had a pronounced preference for 20-30°C, temperatures much warmer than that of its habitat. The lack of temperature preferenda in three species agrees with the hypothesis that imprisoned troglobites tend to lose responses to those environmental variables which are constant in caves. S. bolivari may retain its temperature selectivity because of a slow rate of cave-adaptation. It is hypothised that C. …

Aspetti Ecologici Ed Evolutivi Del Popolamento Di Grotte Temperate E Tropicali: Osservazioni Sul Ciclo Biologico Di Alcune Specie Di Ptomaphagus (Coleoptera Catopidae), Valerio Sbordoni, Marina Cobolli-Sbordoni

International Journal of Speleology

Differences between tropical and temperate cave communities are an important topic in the actual biospeleological thinking. Among the most striking differences is the paucity of terrestrial troglobites in tropical caves. This fact may depend on the higher energy input into tropical caves which lessens the selection pressures for energy-economizing troglobite adaptations. Consequently evolutionary rates would be slowed in tropical caves and, in a date group, troglobites would appear later in such caves than in temperate ones with lower energy input. In order to investigate this point the authors studied the degree of adaptation to the cave environment in two species …

The Evolution Of The Eastern North American Isopods Of The Genus Asellus (Crustacea: Asellidae) Part Ii, Laurence E. Fleming

International Journal of Speleology

This paper is the second in the three part series dealing with the evolution of the North American isopods of the genus Asellus. The generic status of Asellus is discussed with emphasis placed on the newly proposed genera of Henry and Magniez (1968). Use is made of comparative anatomical and where feasible statistical methods during this investigation. The first, shorter portion of the study deals with the presentation of evidence supporting the viewpoint that if "Pseudobaicalasellus” is to be considered a valid genus then it must include the members of the Cannulus Group of Steeves (1965). The …

A New Troglobitic Isopod Of The Genus Lirceus (Asellidae) From Southwestern Virginia, With Notes On Its Ecology And Additional Cave Records For The Genus In The Appalachians, John R. Holsinger, Thomas E. Bowman

International Journal of Speleology

Lirceus usdagalun new species, the first known troglobitic species of the genus, is described from three caves in Lee County, Virginia. The potential taxonomic value of the endopod tip of the male second pleopod, heretofore dismissed as a diagnostic character in this genus, is pointed out. Some general ecological data for the new species are presented, and cave records for other populations of Lirceus spp. from the Appalachians are given.

The land surface reflects partial erosion of Basin and Range fault blocks. The maximtun elevation is 7,170 feet, with relief of 1,400 feet.

The main structural feature is a northwest trending mountain range, which is a west-southwest-dipping fault block bounded on the northeast by the Mimbres fault. Vertical displacement ranges from 150 meters (500 feet) to 1,200 meters (4,000 feet). Rocks exposed along the steep northeastern escarpment range in age …

Petrography, Diagenesis And Environment Of Deposition Of The Gasconade Formation, Lower Ordovician, Southern Missouri, Abd El-Aziz El-Hady A. Borahay

Doctoral Dissertations

"The Gasconade Formation (Lower Ordovician) has been studied in the surface and subsurface in the Ozarks of Missouri and northeastern Oklahoma. The formation is mostly dolomite with a sandstone member at the base (Gunter) and frequent occurrences of chert bodies of different shapes particularly in the middle part.

The dolomite crystals in the lower and upper parts are subhedral to euhedral of equicrystalline to two-size fabric and range in size from 300-600 microns, and subhedral to anhedral of variable fabric and smaller size in the middle part. A sequence of cloudy and clear areas, named zoning, characterizes the euhedral crystals. …

Paleozoic Stratigraphy As An Ore Control Of Hydrothermal, Base-Metal, Sulfide Deposits In New Mexico, John Samuel Sullivan Jr.

Doctoral Dissertations

"Until now the concept or regional stratigraphic control of hydrothermal ore deposits has not received much attention in the literature as a possible exploration guide for locating additional ore bodies. This concept is applied on a regional scale to Paleozoic strata in thirteen mining districts with hydrothermal base-metal deposits in a 35,300 square mile area or southwest New Mexico.

The rocks at the stratigraphic position of the ore-zones are characterized as massive- to thick-bedded with less than 5 percent chert present. The rocks are abundantly to moderately fractured. Fine- to medium-grained dolomite is the dominant host-rock in the lower Paleozoic …

Petrography, Chemical Composition, And Stratigraphic Setting Of The Coals Of North-Central Missouri, William Keith Wedge

Doctoral Dissertations

"Under a grant from the National Air Pollution Control Administration, the Missouri Geological Survey undertook a core drilling program to learn more about the coals in north-central Missouri. The stratigraphic setting and chemical and petrographic characteristics of 43 complete samples of coal recovered from 13 diamond drill holes in the exploration program in north-central Missouri are major contributions of this study. These samples represent twelve different coal beds of the Atokan and Desmoinesian Series of the Pennsylvanian System of Missouri and range in thickness from 9.6 to 44.4 inches. They have an average thickness of 20.4 inches and a combined …
