Certain Trace Element Distribution In The Searchlight, Nevada Quartz Monzonite, Clark County, Nevada, Jai Nandan Shrivastava
Certain Trace Element Distribution In The Searchlight, Nevada Quartz Monzonite, Clark County, Nevada, Jai Nandan Shrivastava
Masters Theses
"The once prosperous gold, silver, copper and lead mines of the Searchlight mining district, Nevada, are situated along the south and western margins of a large quartz monzonite body. This intrudes the Precambrian gneisses and younger lava flows. Associated mineral veins show an eccentric type of zoning around the intrusive.
Seven rock samples of the quartz monzonite representing different parts of the intrusive were analyzed petrographically and spectrographically. Modal analyses and various types of rock alteration were investigated petrographically. Spectrochemical analyses of the rock samples and their major minerals were carried out for certain trace elements. A semi-quantitative method was …

Detection Of Buried Basement Highs By Airphoto Drainage Pattern Analysis, Reynolds And Wayne Counties, Missouri, Papken Aram Zarzavatjian
Masters Theses
"Purpose and Scope: The purpose of this study is to determine if it is possible to detect buried Precambrian igneous hills in Wayne County and the larger part of Reynolds County in southeast Missouri by the use of aerial photo drainage pattern analysis.
The St. Francis Mountains are located in southeast Missouri. They form a part of the Precambrian basement complex, and have been exposed at the surface by the erosion of the lower Paleozoic sediments which covered them. Some of the hills which make up the St. Francis Mountains are exposed to a great degree, while others still have …
