This map shows most of the known occurrences of beryllium minerals and of rocks that contain 0.003 percent or more beryllium (0.01 percent Be0) in the United States (exclusive of Alaska and Hawaii). The occurrences are subdivided on the map according to genesis and size. The genetic types of deposits shown are: pegmatite, vein and replacement deposits (exclusive of tactite), tactite...

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 the minable base- and precious-metal depos its whose ores or

This map shows the location of borate deposits in the United States (exclusive of Alaska and Hawaii).

The chromite deposits in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. In compiling the map, the deposits were classified in five size categories according to the estimated total quantity of chromite present before mining. The map shows, by different symbols, deposits of chromite in ultramafic rocks, beach sands in which chromite is an important...

The copper districts in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. In compiling the map, the estimated total quantity of copper present before mining was used to assign districts to size categories, and both production and reserves are included without distinction as to the status of exploitation. Four categories have been distinguished...

Productive and unproductive deposits of uranium in the United States (exclusive of Alaska and Hawaii) are shown on the accompanying map. These deposits constitute the actual and some of the potential domestic raw-material sources of uranium. Other potential sources of uranium similar to these known deposits remain to be discovered and are probably distributed, at least in part, in the...
