...Debra A. Gevirtzman; Jeffrey F. Mount Abstract A pre-trilobite shelly fauna was recently discovered at Mt. Dunfee, near Gold Point in Esmeralda County, Nevada. These fossils occur in the lower to middle portions of the lower member of the Deep Spring formation, approximately 1,000 m below the first...

..., the Shuram negative carbon isotopic excursion occurs within the Rainstorm Member near the top of the Johnnie Formation, followed by a remarkable valley incision event. At its type locality in the northwest Spring Mountains, Nevada, the Johnnie lithostratigraphy consists of three distinctive sand-rich...

... Lake fault. U-Pb ages of detrital zircons from the Neoproterozoic Wyman Formation, the uppermost Proterozoic Reed Dolomite (Hines Tongue Member), and clastic strata of the Lower Cambrian Deep Springs, Campito (Montenegro Member), Poleta, and Harkless formations reflect ultimate derivation from...

... and recrystallization may alter the original carbonate fabrics. A columnar stromatolite composed of calcium carbonate (ca. 544 Ma) was chosen from the Precambrian-Cambrian transition near Mount Dunfee, Esmeralda County, Nevada. Although composed of calcium carbonate, the Mount Dunfee stromatolite formed...

... and is inferred purely from the western boundary of Paleozoic units exposed at the southern basin edge, just north of Mount Dunfee. The gravity high that divides the northern domain into two subbasins is due to a major north-northeast–trending structure with a significant down-to-the-east component of ∼300 m...
