Petrologic study of sediments from selected central Texas caves

Petrologic study of sediments from selected central Texas caves

The petrologic study of cave sediments is a new field whose history dates back only about 30 years. Most previous work has been done in Europe, with very little in North America. This is the first petrologic study of sediments of Texas caves. Sediments from the 11 Central Texas caves investigated pr...
