Stratigraphic Section and Fusulinids of the Bird Spring Formation Near Lee Canyon, Clark County, Nevada
During Late Mississippian, Pennsylvanian, and Permian time, several thousand feet of predominantly carbonate sediments accumulated in southern Nevada and southeastern California. Because of their lithologic unity these rocks constitute a single formation, the Bird Spring Formation. One of the best sections is exposed along the eastern front of the Spring Mountains about 35 miles northwest of Las Vegas, near Lee Canyon, Clark County, Nevada ... There the formation is greater than 7,000 feet thick, is broken only by minor faults, and contains a prolific fusulinid fauna. This report deals with that thick stratigraphic section and its contained fusulinids. An attempt has been made to correlate the various divisions with units in the mid-continent region where the most extensive studies on fusulinids have been made.
