The Bdellidae (Acarina) Of The Australian Realm, Warren T. Atyeo

Bulletin of the University of Nebraska State Museum (1924–2023)

Although primarily a systematic study, variations in the integumental striae and chaetotaxy of the legs are discussed. The genus Octobdellodes Atyeo, 1960 is synonymized with Bdellodes Oudemans, 1937 and the sugenus Cytobdella Mihelcic, 1958 is synonymized with Cyta von Heyden, 1826. The genus Bdellodes is divided into the subgenera Bdellodes and Hoploscirus Thor, 1937 (=Thoribdella Grandjean, 1938, new synonymy). Twenty-two species are now known to occur in New Zealand and the outlying islands. These include four known species: Bdella iconica, Bdellodes (Roploscirus) lapidaria, B. (R.) reticulata, and Cyta latirostris, and eighteen new species: Bdellodes (Bdellodes) harpax, B. (B.) oraria, …

A Preliminary Report On The Itasca Bison Site, Creighton T. Shay

Journal of the Minnesota Academy of Science

In the summer of 1937 excavations conducted by the University of Minnesota Anthropology Department in Itasca State Park yielded extinct bison and other animal remains along with several stone artifacts. A preliminary notice was published in Science shortly after excavation was completed (Jenks, 193 7). The bones were extracted from a marl layer underlying a peat bog near the south end of the west arm of Lake Itasca. The deposit was discovered during construction of a road bridge over Nicollet Creek adjacent to the site. Material in the following report was assembled from unpublished field notes and records on file …

Geology Of The Unconsolidated Deposits Of Lake County, Indiana, Reuben J. Vig

Theses and Dissertations

Lake County is in the extreme northwestern corner of Indiana. The county is divided into three physiographic units: (1) Calumet lake plain, (2) Valparaiso moraine, (3) Kankakee glacioflucial plain.

The Calumet lake plain was covered by glacial Lake Chicago. Beach lines show the areal extent of the various phase of the lake’s history. The Valparaiso moraine, a broad upland, trends east-west across the county. An end moraine on the north side of this upland is correlated with the Tinley moraine in Illinois. The Kankakee glaciofluvial plain, formerly marshland, slopes gently from the Valparaiso moraine to the Kankakee River.

The bedrock …

Hydrogeology Of Reservoir Sites In The Meramec River Basin, Missouri., John H. Anderson

Masters Theses

"Governmental and private agencies have proposed construction of multiple purpose dams in the Meramec River Basin for flood control, conservation, recreation and possible power development. Evaluation of the effects of reservoirs created by these dams on ground water conditions has not been published. Study of possible effects led to the thesis that prediction of changes in ground water conditions could be made.

Several limited applications of ground water geology techniques to the problem of reservoir-ground water relations were studied; no thorough previous studies were found. Apparently, complete studies have not been undertaken by even the larger agencies.

Mollusks From Wisconsinan (Pleistocene) Ice-Contact Sediments Of The Missouri Coteau In Central North Dakota, Samuel J. Tuthill

Theses and Dissertations

This thesis here abstracted was written under the direction of Frank D. Holland, Jr. and was approved by Wilson M. Laird and George C. Wheeler as members of the examining committee, of which Dr. Holland was Chairman.

Geologic and paleontologic evidence indicates that numerous mesotropic, temperate, water bodies were present while drift-covered bloacks of stagnant glacier ice, unplaced during Woodfordian (late Wisconsinan, Pleistocene) time, underlay the Missouri Coteau district (approximately 50 by 300 miles in extent) in central North Dakota.

Fossil mollusks, contained in sediments deposited in contact with the stagnant ice at 40 sites, are represented by 23 species …

A Paleontological Study Of The Gunflint Microfossil Assemblage, J. William Schopf

Honors Papers

Precambrian microfossils discovered in nonferruginous charts of the lower "algal" members of the Gunflint formation of southern Ontario are of great interest in the evolutionary scheme of primitive life. The environment of deposition of the deposit, and the indigenous and biogenic nature of the microfossil assemblage are considered. A discussion of the small but diversified assemblage, including twelve micro-forms, seven of which have not previously been reported, is presented.

Pegmatites Of The Anderson Ridge Quadrangle, Fremont County, Wyoming, Hassan A. Etr

Masters Theses

“The oldest rocks in the area consist mainly of para- schists of low to medium rank and restricted higher rank sillimanite schist. The entire series has been at least double folded. The most apparent are tight north to north- east trending folds. These have been intruded in the northern part of the area by a batholithic body of granitic composition, a granitic stock, a pegmatitic granite, a granitic sill-like body and different types of pegmatite dikes and sills. The youngest intrusions are a series of northeast trending basic dikes and sills. A major easterly trending transverse fault and a series …

The Diagenetic Origin Of The Dolomites, Chert, And Pyrite In The Jefferson City Formation., Erik Hans Schot

Masters Theses

"Diagenesis designates all modifications which a sediment undergoes during and following deposition and prior to complete lithification, metamorphism, deep burial, and orogenesis.

Probably the dolomites of the Jefferson City Formation resulted from alteration at, or below the sea floor or the depositional interface and during diagenesis. Diagenetic dolomitization or penecontemporaneous alteration presumably involves a reaction between the calcium carbonate sediments at/or below the sea floor or the depositional interface and magnesium salts in solution or suspension in the basal layer of contacting sea water, or in the initial pr connate water trapped in the sediment.

The cherts of the Jefferson …

The Location Of Underground Points By Means Of A Magnetic Dipole, Anthony Del Prete Jr.

Masters Theses

"The object of this study was to design, construct, and test an electromagnet that could, from an underground location, generate a magnetic field which could be located at the surface, and that was portable enough to be carried through a cave. This could then be used to locate points in a cave relative to the surface.

A 20 foot solenoid composed of four five-foot sections was built and magnetized by a lightweight rechargeable four-cell eight volt battery. The total weight of the equipment was 30 pounds.

The magnet was calibrated by erecting it and measuring its vertical intensity with a …

Sedimentary Petrography And Environments Of Deposition Of The Plattin Group, Cliffdale Hollow, Jefferson County, Missouri., Narendra M. Naiknimbalkar

Masters Theses

"Petrographic and depositional environments studies were completed on selected Plattin Limestone rock-samples from the Drill-cores of Cliffdale Hollow area, Jefferson County, Missouri.

Petrographic analysis of forty-four thin sections and the detailed megascopic study of the samples revealed the different types of limestone rocks which were classified on the basis of Folk's (1959) Carbonate Classification. As to the environments of deposition of the Plattin Limestone determined by petrographic study, it has been concluded that this environment was one of low to medium agitation and low to medium organic activity.

Chemical analysis of the Plattin Limestone samples revealed the presence of the …

Stereoradiography As Applied To Problems Of Petrology., Martin Goldstone

Masters Theses

"Stereoscopic examination of radiographs of rock and ore samples allows a rapid, cursory determination of texture and structure without time consuming preparation and use of thin sections. In addition, volumetric estimates of known mineral components can be made providing they possess significantly different x-ray absorption characteristics.

Stereoscopic effect was most pronounced for specimens having well defined components of structure such as bedding, banding, lineation, inclusions, textural variations and moderate to large x-ray absorption differences. In general, these conditions were best met by ores or ore minerals with their related gangue minerals.

Stereoscopic examination was not successful in revealing twinning or …

Fossil And Recent Beryciform Otoliths: An Adjunct To Ichthyological Classification., C. Kurt. Lamber

Masters Theses

"Otoliths are calcareous bodies, of consistent form, secreted in the auditory labyrinths of some higher fishes. Of three pairs, only the taxonomically important earstones (sagittae) are considered here. Specifically, this study is restricted to the sagittae of beryciform fishes (Order Beryciformes). Removal of some taxa from the order, and the possible relating of others, is suggested.

The morphology of beryciform sagittae is described, and three basic supra-familial groups are recognized. Diagnostic characters for families are given, with diagnoses of genera added. Sagittae of characteristic species are illustrated.

Otoliths of fossil beryciform fishes, as known from specimens and published illustrations, are …

Geology Of The Northern Half Of The Ellington Quadrangle Missouri., Robert Charles. Thornton

Masters Theses

"Geologic mapping has been completed for the northern half of the Ellington Quadrangle, Missouri. Rocks exposed in the thesis area are Precambrian and Paleozoic in age. The Precambrian rocks are granites and felsite. The Paleozoic rocks include the Potosi and Eminence Formations, of Upper Cambrian age, and the Gasconade Formation of Ordovician age. Distinction between the Potosi and Eminence Formations is difficult because of conformable and transitional relationships. In the thesis area sufficient evidence was available to separate the dolomites of the Potosi and Eminence as mappable units. This mapping should be useful as a basis for more detailed geologic …

Pleistocene Formations In Indiana, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

The system of stratigraphic classification used in North America for all sedimentary rock units except nonmarine deposits of the Pleistocene Series established groups, formations, and smaller units based on objectively determined characteristics of the rocks and not on geomorphology or subjective features, such as geologic time. Not all students of the nonmarine Pleistocene have kept these two kinds of units distinct from each other. The Pleistocene sediments of Indiana and the surrounding States are continental in origin rather than marine, and thus they show far less lithologic homogeneity than sediments and rocks of marine origin. Nevertheless, these Pleistocene sediments can …

The Structural And Stratigraphic Relationships In The Paleozoic Rocks Of Eastern North Dakota, Frederick V. Ballard

Theses and Dissertations

The thickness and areal extent of the commonly defined Paleozoic rock units in eastern North Dakota has been determined by a study of mechanical well logs. Isopachous wops of these units reveal several positive areas which persisted and influenced sedimentation and unit thickness throughout most of the Paleozoic Era. Precambrian topographic highs of either erosional or structural origin produced those influences in early Paleozoic time, whereas later effects resulted from periodic structural rejuvenation of the original highs. The activity of those highs appears to be related to the location of the basin depocenter. The most prominent highs were in Cavalier, …

Pelecypoda From The Lower Fox Hills Formation (Upper Cretaceous) Of Emmons County, North Dakota, Rodney M. Feldmann

Theses and Dissertations

The Fox Hills Formation in Emmons County, North Dakota, consists of 250-350 feet of medium to fine grained sand and sandstone with some shale interbeds. In Emmons County, the four members, Trail City, Timer Lake, Bullhead, and Colgate are not as distinct lithologically as they are in the areas from which they were described; thus, the unit has been subdivided into a lower part consisting of crossbedded sand and sandstone with calcareous, fossiliferous concretions and an upper part consisting of interbeds of buff sand and chocolate shale.

The gradational change from Pierre Shale lithology to the sands of the overlying …
