SHALE, SILTSTONE, SANDSTONE, CHERT-PEBBLE CONGLOMERATE, AND LIMESTONE-Includes units such as Pilot Shale, Joana Limestone, Chainman Shale, and Diamond Peak Formation in northern and eastern Nevada and Narrow Canyon Limestone, Mercury Limestone, and Eleana Formation in southern Nevada
The Pilot Shale, Joana Limestone, and Chainman Shale has been previously mapped as the White Pine Group (Hose and Blake, 1976). The stratigraphic units included in this map unit vary in relative abundances of lithologies as well as thicknesses, anywhere from less than one hundred feet to a few thousand feet. Generally the units located in the north thin southward and vice versa. Almost all of the units have some combination of all ofthe lithologies listed below. In southern Eureka County, there is an outcrop included in this unit which Roberts and others, 1967, maps as part of the Newark Canyon Formation, a unit of shale and sandstone with limestone and conglomerate of Early Cretaceous age; this unit is not included in the age coding below although it could be lithologically similar to the rest of this unit. The Elena Formation is at least 7,700 feet thick; the Elena is lithologically similar to the Chainman Shale and Diamond Peak Formation (Cornwall, 1972).
