The Geology Of The Southeast Quarter Of The Bone Mountain Quadrangle, Oregon, Richard Cortland Kent

Dissertations and Theses

This thesis is a study of the geology of the southeast quarter of the Bone Mountain Quadrangle. The bedrock geology mapped includes about 56 square miles.The Klamath Mountain and Coast Range Provinces of southwestern Oregon are represented in the area. Rocks in the area include the Rogue, Dothan Riddle, Days Creek, upper member of the Umpqua and Tyee Formations. The ages of these rocks range from Late Jurassic to middle Eocene. Late Jurassic ultramafic and mafic intrusive rocks associated with the Rogue Formation occur in the Klamath Province. The metavolcanics of the Rogue Format ion and an associated linear belt …

Petrology Of The Nemeiben Lake Ultramafic And Associated Nickel-Sulphide Deposits, Anantaramam Peddada

Geology Theses and Dissertations

The Nemeiben Lake ultramafic body is located in the center of Saskatchewan, Canada, within the Churchill Province of the Canadian Shield. The ultramafic rocks consist of serpentinites, partly serpentinized and uralitized pyroxenite, and unaltered pyroxenite. Associated sulphide mineralization is of disseminated, net texture, and fracture filling types. The ore minerals present are pyrrhotite, pentlandite, chalcopyrite, pyrite, marcasite, violarite, bravoite and native copper. The sulphides are considered to be initially of magmatic origin formed from a sulphide melt separated at a late stage during crystallization of the ultramafic rocks. Subsequent serpentinization has locally redistributed the ores.
Serpentinization in the Nemeiben Lake …

Stratigraphy And Sedimentary Structures Of A Middle Bloyd Fluvial Sandstone, Washington And Madison Counties, Arkansas, John M. Glenn

Journal of the Arkansas Academy of Science

A prominent quartz-pebble-bearing sandstone unit crops out at stream level along the East Fork of the White River in Madison County. Detailed geologic mapping indicates that the unit is stratigraphically positioned between the Brentwood and Dye Shale Members of the Bloyd Formation and is not the Greenland Member of the Winslow Fromation as previously supposed. Sedimentary textures and structures of the unit indicate that it was deposited by competent, unidirectional currents flowing in a southerly direction. These currents were related to a broad braided stream system.

Interbasin Water Transfers And Groundwater Regulation In Nebraska, D. D. Axthelm, V. H. Dreeszen, C. A. Lewis

Conservation and Survey Division: Faculty and Staff Publications

On November 29, 1971, the Hamilton County Ground Water Con·­servation District sponsored a meeting on groundwater management and regulation. The meeting was held at Aurora, Nebraska, and was designed for irrigators from groundwater conservation dis­tricts and county irrigation associations. Various men from state and federal agencies spoke about a variety of problems that a.re related to groundwater management. Two of the talks that were presented at the meeting are reproduced here, as is a discussion of the rules and regulations that relate to the use of groundwater in the state of Nebraska.

An Evaluation Of A Stable Isotope Of Dysprosium For Labeling And Tracing Sedimentary Particles, Charles Glenn Boone

OES Theses and Dissertations

An evaluation of the application of dysprosium oxide as a tracer coating to surface label sedimentary particles is made. Physical and chemical properties of the labeled sand are studied. Effective diameters and settling properties of the tracer sand are compared with unlabeled sand. A total of 8.51 kg of labeled sand was placed on the beach at Camp Pendleton. Dispersal patterns obtained 1 and 4 hours after tracer injection indicate a general down current mean tracer migration rate of 0.21 cm/sec (0.42ft/sec). An absolute detection limit of 4 or 5 parts per 100,000 and a real detection limit, after field …

Grain Size Reconnaissance Of The Virginia-North Carolina Inner Shelf Analysis By Settling Technique, Robert Bailey Sanford Jr.

OES Theses and Dissertations

The 2-fold purpose of this study is to calibrate a Rapid Sediment Analyzer and to use it to aid in the determination of the genesis of sediment on the inner continental shelf between Cape Henry and Cape Hatteras. Rapid Sediment Analyzer calibration was conducted by comparison of sieving and settling results of similar sands.

The study area was divided into sediment provinces by both a qualitative procedure (grain size and topography) and a quantitatively procedure (factor-vector analysis). Qualitative provinces are beach and surf, upper shore face, lower shore face, sea floor, and terminal shoals. The berm fines from each terminal …
