Microfossils From The Big Springs Limestone (Pennsylvanian) In Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Sand-sized residues from partial acetic acid digestion of three samples of the Big Springs Limestone Member of the Lecompton Limestone (Pennsylvanian) from two localities in Cass County, Nebraska, have yielded sixteen genera of microfossils from five major groups of organisms and numerous other whole and partial fossils from seven other groups not identified to the genus level. These fossils include: Protozoa (fusulinids*); Porifera (one spicule type); Bryozoa (two undetermined genera); Brachiopoda (fragments); Gastropoda (two undetermined forms); Ostracoda (Bairdia*, Hollinella*, Moorites*, and one undetermined genus); Crinoidea (whole and partial ossicles*); Echinoidea (whole and partial spines and spine bases*); Holothuroidea (Achistrum …

Calico Rock Sandstone Member Of The Everton Formation (Ordovician), Northern Arkansas, Raymond W. Suhm

Journal of the Arkansas Academy of Science

Surface and subsurface stratigraphic studies in northeastern Arkansas show the Calico Rock Sandstone (Middle Ordovician) to be a lobate sand body up to 200 ft thick. The environment of deposition is considered from a study of grain characteristics, ripple marks, subjacent and superjacent units and unpublished isopachous maps. The data indicate the Calico Rock Sandstone formed in a transgressing Everton sea as a barrier island and near shore sand complex. The quartz sand was derived from a northern source and was distributed by southwestward flowing longshore currents.

A Study Of Some Petrologic And Structural Aspects Of The East Dover Ultramafic Bodies, South Central Vermont, Mark Allen Hoffman

Geology Theses and Dissertations

INTRODUCTION (pp.1-4)

Mineralogical, textural and chemical changes of ultramafic rocks in response to regional deformation and metamorphism are, at best, imperfectly known (Miyashiro, 1973, p. 30). In Vermont, which has an extremely prominent and well-exposed belt of ultramafics (fig. 1), investigation of these rocks has largely been directed toward such processes as serpentinization, steatitization, and the formation of metasomatic zones at the contacts with country rocks. With few exceptions, there is a lack of detailed descriptions of regional metamorphic textures, mineralogy, and structures developed in the Vermont ultramafic rocks. It is the main purpose of this thesis to describe the …

The Persian And Arabic Destructions Of Caesarea Maritima: The Historical And Stratigraphical Data, Sarah Eleanor Sypher

Theses and Dissertations (Comprehensive)

This thesis presents the historical and stratigraphical evidence for the Persian and Arabic destructions of Caesarea Maritima. Its main purpose is to discover whether the stratigraphical data coincides with the historical information concerning the city in the sixth and seventh centuries A.D.

The archaeological data are the results of four seasons of excavation (1971, 1972, 1973, 1974) carried out by the Joint Expedition to Caesarea Maritima under the direction of Dr. R.J. Bull, Drew University, Madison, N.J. It is supported by a consortium of twenty-one Colleges, Seminaries, and Universities, including Wilfrid Laurier University, and is sponsored by the Albright Institute …

Microfossils From The Upper Severy Shale (Pennsylvanian) Near Dubois, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Organic rich limestone nodules within the Severy Shale Formation collected directly above the Nodaway Coal Member near DuBois, Nebraska, have yielded a rich microflora and microfauna. The microflora includes Triletes megaspores, seeds, cuticle, and pieces of wood with well preserved structures. The microfaunal skeletal material is either partially or completely replaced by pyrite, marcasite, or, in rare cases, by sphalerite. The following major invertebrate groups and genera within these groups have been identified to date: Bryozoa (one undetermined genus); Brachiopoda (Juresania) ; Gastropoda (four undetermined genera); Ammonoidea (one undetermined genus); Ostracoda (Amphissites, Coryellites, Hollinella, Macrocypris); Echinoidea (five spine types); and …

Biostratigraphic And Lithostratigraphic Analysis Of The Hindsville Limestone (Mississippian) In Northwestern Arkansas, Robert C. Grayson Jr.

Journal of the Arkansas Academy of Science

Several lithofacies can be recognized within the Hindsville Limestone (Mississippian) in its type area near Hindsville, Madison County, Arkansas. Lithofacies are based on petrographic analysis of matrix and constituent particles, particularly ooliths and skeletal grains. Hindsville deposition began with skeletal calcilutite incorporating chert rubble from the underlying Boone Formation. Increasing energy produced a sequence of skeletal calcarenites and oolites, and the end of Hindsville deposition was marked by a return to impure skeletal calcilutite. Conodonts recovered from the Hindsville Limestone include species of Cavusgnathus and Gnathodus. On the basis of reported ranges of these elements, the Hindsville appears to correlate …

Biostratigraphy Of The Type Yamhill Formation, Polk County, Oregon, Larry R. Gaston

Dissertations and Theses

One hundred and seventy-four species and varieties of fossil Foraminifera are recorded from thirty-eight localities in the Siletz River Volcanics, Yamhill and Nestucca Formations exposed along Mill and Gooseneck Creeks, in the Northern Coast Range of Oregon. Marginulina holmesi is described as new. The Foraminifera indicate that this sequence was deposited during late Ulatisian and Narizian time, in marine waters at bathyal or lower neritic depths, with cool surface temperatures. The Yamhill Formation can be correlated with Moody Shale member of the Toledo Formation and the Coaledo Formation of Oregon; the McIntosh and Aldwell Formations of Washington; and the upper …

The Pierre-Niobrara Unconformity In Western Nebraska, Harold M. Degraw

Conservation and Survey Division: Faculty and Staff Publications

The Pierre-Niobrara unconformity, one of several significant unconformities in the Cretaceous System of the Western Interior region, has not generally been recognized. Detailed correlation of electric logs of a large number of wells in western Nebraska provides evidence of its existence. Isopach maps of the beds occupying three identifiable stratigraphic intervals - a redefined Niobrara Formation, an unnamed uppermost Niobrara unit, and an unnamed basal Pierre unit, which includes the Ardmore Bentonite - provide recognizable geologic patterns that permit reconstruction of the stages of development of the unconformity. The upper part of the Niobrara Formation has been truncated in several …
