BITUMINOUS SANDSTONE. A sedimentary rock of siliceous character, containing more or less asphalt or bitumen. When rich in bitumen it is a valuable economic product; sometimes it is used directly as a paving material, but more often it is previously subjected to a process of refining. In the United States it is mined in California, Kentucky, and Indian Territory. The output in 1900 was 34,277 short tons, valued at $138,892. Consult the volumes of The Mineral Industry, especially Vol. VIII. (New York, 1900). See Bitumen; Asphalt.
