The following list of common minerals and mineral products has been prepared by the Bureau of Economic Geology of the University of Texas as a brief index to the mineral resources of Texas. Many minerals occur in the State in addition to those here listed, with the less common ones being omitted. Only the more important localities are provided, as it is impractical to list all occurrences of the common minerals.

Of the minerals and mineral products enumerated, about twenty are now being commercially utilized. The present annual production of these minerals is indicated in the following table, based on the returns for 1925, except for petroleum, which is for 1926. The returns are estimated for clay products, mineral water, and petroleum.
