"Definition Of The Study. The study consists of an investigation of the variation in the temperature of formation of sphalerite on the 500 and 1500 ft levels of the Balmat zinc deposit at Balmat, New York. A subsidiary investigation was performed on the use of x-ray fluorescence as a means of chemical quantitative analysis. Twelve samples of sphalerite from the 500 ft level and 13 samples from the 1500 ft level were analyzed for atomic percent iron content by measuring Zn/Fe x-ray fluorescent ratios. The x-ray fluorescent ratios were standardized by ''wet" quantitative analysis. The results of the analyses are …
Pre-Cambrian Geology Of Washington County Area, Missouri, Gordon Blair French
Pre-Cambrian Geology Of Washington County Area, Missouri, Gordon Blair French
Masters Theses
"The Problem.
Washington County, Missouri contains a limited number of outcrops of pre-Cambrian igneous rocks, the majority of which are in the extreme southern part of the county. The known association of lead ore with buried or partially buried pre-Cambrian igneous knobs and ridges in this part of Missouri has led the St. Joseph Lead Company to prospect in areas known to contain these features. In its exploration program, the St. Joseph Lead Company has drilled a number of prospect holes which have encountered other occurrences of pre-Cambrian igneous rocks within the limits of Washington County. This drilling, correlated with …
Geology Of The Northwest Quarter Of The Washington Quadrangle, Missouri, James Anthony Martin
Geology Of The Northwest Quarter Of The Washington Quadrangle, Missouri, James Anthony Martin
Masters Theses
"This report presents the results of detailed mapping of the geology of the northwest quarter of the Washington Quadrangle, Missouri. Extensive mapping and stratigraphic work have been done in St. Louis and St. Charles Counties to the east and in Callaway and Boone Counties to the west. These two well studied areas are separated by approximately 45 miles. This study adds geologic information to the area immediately between the above locations. In this area a gentle regional dip to the north permits a study of sediments ranging in age from lower Ordovician in the south to late Paleozoic and Pleistocene …
