The Regression Of The Flood In Virginia, James C. Rakestraw, Jim Melnick

Proceedings of the International Conference on Creationism

The geology, tectonics, and hydraulics of the regression of the Flood formed much of the geomorphology of Virginia. Opportunities to view and study geology and geomorphology are available through visiting parks, traveling on public roads, and viewing geographic information system (GIS) resources.

Virginia is part of the North American Plate. A series of “blocks” of basement rocks within the plate underlie the geomorphological provinces of Virginia. These “blocks” form a series of steps between the Atlantic Ocean Basin and the Blue Ridge. The “Fall Line” found in Virginia is a fault between two blocks of basement rock. The basement rocks …

Grain Size Analysis Of Massie’S Creek Near Flax Pond And Community Park, Andrew R. Rivera

The Research and Scholarship Symposium (2013-2019)

The goal of this research is to better understand the stream bed conditions at the confluence of North Fork and South Fork Massie’s Creek next to Community Park in downtown Cedarville, OH. Stream depth as well as sediment type where determined as a result of field work done for this project. The depth data was then used to create a contour map of the pool behind the low-head dam that defines the lower boundary of the confluence area. Sediment distribution is represented on this map based on laboratory particle size analysis and gross piratical size analysis done in the field. …

Correlation Of Basal Cambrian Sandstones Across North America, Joshua W. Perez

The Research and Scholarship Symposium (2013-2019)

A thin, widespread sequence of siliciclastic strata ranging from lower to upper Cambrian age overlies Precambrian crystalline and metamorphic basement rock bounded by the Great Unconformity. This sequence is mainly comprised of basal Cambrian sandstones which can be subdivided into three distinct suites of lithofacies transitioning in age across most of North America. From the west, which is most notable for the Tapeats sandstone of Arizona and Nevada, lies gravelly to boulder sized conglomerates directly overlying basement rock. Eastward, the lower to middle Cambrian consists of a variety of ledge-forming sandstones which contain various areas rich in cross bedded, as …

Relationship Of Surrounding Geology To Well Recovery Properties For Selected Cedarville University Water Supply Wells, Kaitlyn Sturm

The Research and Scholarship Symposium (2013-2019)

This study was conducted to ascertain the relationship between geology and recovery rates of three selected Cedarville University water supply wells. In order to determine the recovery rates, the three selected wells were individually pumped down and then water level measurements were taken as the water levels rose in the well bore. The collected field data was analyzed and compared to the drillers’ well logs from when the wells were originally drilled. The geologic conditions that were examined for the area immediately surrounding the wells included: bedrock lithology, glacial drift characteristics (type and thickness), ground-surface topography, and bedrock topography. The …

Estimates Of Maximum Past Overburden For The Pierre Shale, Hayes Area, South Dakota, Thomas L. Rice

Science and Mathematics Faculty Publications

The Pierre Shale of the Northern Great Plains area of the United State is an Upper Cretaceous shale which was deposited in a marine environment. Geotechnically, the shale has been classified as an overconsolidated clay-shale. In South Dakota the Pierre Shale crops out extensively in the central and western portions of the state.

In this study an investigation was conducted for the purpose of clarifying and examining the existence of a discrepancy between geotechnically and geologically derived estimates of maximum past overburden for the Pierre Shale at Hayes, South Dakota.

The geological determination involved examining the topographic high points of …
