Gypsum and anhydrite in the United States, exclusive of Alaska and Hawaii
Charles F. Withington
1962, Mineral Investigations Resource Map 33
The distribution of gypsum and anhydrite in the United States (exclusive of Alaska and Hawaii) is shown on the accompanying map. In addition to mines, open pits, and occurrences, the map shows the outcrop patterns of gypsum-bearing fomations and other outlines of the important evaporite basins in which gypsum and...
Bismuth in the United States, exclusive of Alaska and Hawaii
John Roberts Cooper
1962, Mineral Investigations Resource Map 22
The bismuth-bearing deposits in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. In compiling the map the deposits were classified into two categories: 1) those that have produced bismuth or are regarded as potential sources based on available information (in general, this category includes...
Vanadium in the United States, exclusive of Alaska and Hawaii
Richard Philip Fischer
1962, Mineral Investigations Resource Map 16
The productive and potential raw material sources of vanadium in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. This map is at the scale of 50 miles to the inch. The text accompanying the map briefly describes the major geologic types of deposits of...
Mercury in the United States, exclusive of Alaska and Hawaii
Edgar Herbert Bailey
1962, Mineral Investigations Resource Map 30
This map shows the location of mercury districts and deposits in the United States (exclusive of Alaska and Hawaii).

Three size categories, based on production and estimated reserves, are distinguished and indicated by...
Copper in the United States, exclusive of Alaska and Hawaii
Arthur R. Kinkel Jr., N. P. Peterson
1962, Mineral Investigations Resource Map 13
The copper districts in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map.
