This thesis suggests that in parts of Nevada such as Crystal Peak, Coal Valley, and Coaldale lignites were deposited in penecontemporaneous environments containing similar floral assemblages indicating a uniform climatic regime may have existed over west-central Nevada during late Barstovian-early Clarendonian time. At all locations, excepting Tick Canyon, field and palynologic evidence indicates low energy, shallow, fresh-water environments existed during the deposits of lignite sequences.
