Abstract
The Chuar Group, approximately 5,250 feet thick, offers a readily-dated, accurate record of tectonic, environmental, and biological changes that began the Phanerozoic Eon. This group was deposited during the extension of the north-tending Butte fault system and contains many cyanobacteria, algae, and heterotrophic protists.
