DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP I-1773 U.S. GEOLOGICAL SURVEY

METALLOGENIC MAP OF ZINC, LEAD, AND BARIUM DEPOSITS AND OCCURRENCES IN PALEOZOIC SEDIMENTARY ROCKS, EAST-CENTRAL UNITED STATES

By Sandra H. B. Clark

INTRODUCTION references to each deposit or occurrence. The compilation is generally restricted to deposits and mineral occurrences that have been described This pamphlet, which accompanies map I-1773, is a descriptive in the literature, although data for a few occurrences are from compilation of 545 zinc, lead, and barium districts, deposits, and unpublished sources. Dashes indicate unknown or no information occurrences in Paleozoic sedimentary rocks in the east-central United available. States. Numbers generally are assigned to the deposits and occurrences in a left to right and top to bottom pattern within each state (listed alphabetically). The numbers correspond to the numbers within each CONTENTS state on the accompanying map. More than one name is given for localities that have been called by different names at different times. The State Number of Locations Page name listed first is that most recently or commonly used in the literature, or is from a nearby geographical locality. Other names for the Alabama 9 2 occurrences are listed in parenthesis. Names of subdistricts and (or) some Georgia 9 4 of the larger mines are listed in parentheses after district names. These Illinois 33 6 names are included to aid the reader in identifying localities as listed in Indiana 148 11 other reports and are not necessarily current. This is especially true for names of quarries. which may or may not be currently operating or being Kentucky 3 24 operated by the same company. Maryland 1 25 Commodities are listed in order of abundance, if known, in the order Michigan 8 26 listed in previous reports, or, if there is no other information, Pb and Zn New York 34 27 before Ba. Minor or byproduct commodities are in parentheses. 71 31 Commodities are shown by chemical symbols: Pb, lead; Zn, zinc; Ba, Ohio barium; Cu, copper: F, fluorine; As, arsenic; U, uranium; Ag, silver; Cd, Pennsylvania 77 39 cadmium. Size is given as occurrence or prospect or as small, medium Tennessee 56 49 or large for deposits which have been mined. Definitions of small, Vermont 56 59 medium and large are those used by Guild (1981, p. A4). Stratigraphic Virginia 5 60 names and geologic ages are taken from the references cited and do not West Virginia 12 necessarily conform to the usage of the U.S. Geological Survey. 67 References listed are selected to provide information on the specific Wisconsin 23 69 deposit or occurrence shown, but are not comprehensive listings of References cited 72 ALABAMA
