A Study Of The Genesis Of The Krueger Zinc Deposit And The Near-By Barite Deposits Of The Potosi Quadrangle, Washington County, Missouri, Attilio Ligasacchi
Masters Theses
This thesis deals with the study of the genesis of the Krueger zinc deposit and the near-by barite deposits of the Potosi quadrangle, Washington County, Missouri.
The rocks outcropping in the quadrangle embrace Pre-Cambrian and Lower Paleozoic formations, the Potosi and Eminence being the most important formations with regard to the studied deposits.
The few structures present in the area of the vertical type and are more abundant in the southern part of the quadrangle.
Special emphasis is placed on the relationships between the barite, the associated sulfides, and the host rock.
Geometric and geochemical criteria are studied in detail …

"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 …
