Book excerpt: Excerpt from Areal Geology of the Western Mojave Desert, California The major domestic source of boron compounds is a single large deposit of sodium borate near the town of Boron. This deposit is in lacustrine shale of the upper (middle Miocene) part of the Tropico Group. The lacustrine shale is practically devoid of other saline minerals. The source of the borate min erals is presumably volcanic thermal springs genetically related to basalt flows that underlie the shale. The small marginal and outlying deposits are mostly of calcium borate. Fieldwork was done during the spring, autumn, and winter months from 1952 to 1955 and during short intervals from 1956 to 1959.
