Titanium in the United States, exclusive of Alaska and Hawaii

The accompanying map shows the location of the principal deposits of titanium minerals in the United States (excluding Alaska and Hawaii). Four broad geologic categories of deposits have been distinguished on the map by the shapes of the symbols, and relative importance is indicated by their size. The smaller deposits and the deposits for which adequate data are lacking can only be rated as "potential, unevaluated, or small". The deposits placed in the next category have been characterized by modest production or can be described as having "significant potential". The larger deposits, for which, more information is available, arc divided into two categories, based on estimated production plus reserves: those containing 1,000,000 to 10,000,000 tons of TiO2, and those having more than 10,000,000 tons of TiO2.
