Gravel sources of knappable alibates silicified dolomite

Geoarchaeology, 1993
AbstractAlibates silicified dolomite is one of the principal knappable lithic materials indigenous to the Southern High Plains. Prehistorically, this material was extensively quarried along the Canadian River in Potter County, Texas. Some of these quarries are preserved in what is now the Alibates National Monument.
