Black Mat (Material Keyword)

DOCUMENT Full-Text Kathryn Puseman.

A total of seven bulk samples of organic material from black mat deposits in the Upper Las Vegas Wash, Nevada, were floated to recover organic fragments suitable for radiocarbon analysis. The black mat deposits are associated with late Pleistocene paleo-spring sediments. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. A single charcoal sample also was submitted for identification.
