Conglomerate, sandstone, shale, and dolomite of Diablo Formation below and shale, sandstone, and conglomerate of Candelaria Formation above (NVTRPd;0)

State	Nevada
Name	Conglomerate, sandstone, shale, and dolomite of Diablo Formation below and shale, sandstone, and conglomerate of Candelaria Formation above
Geologic age	Early Permian to Early Triassic
Original map label	TRPd
Comments	In Mineral and Esmeralda Counties, the Diablo Formation ranges from 200 to 400 feet thick and is chiefly composed of sandstone and grit and dolomite, the relative proportions of which vary locally (Ross, 1961, Albers and Stewart, 1972); in northern Nye County, the Diablo Formation ranges anywhere from 131 feet to 3,280 feet thick and is composed of siltstone interbedded with conglomerate, sandstone, grit, and limestone (Kleinhampl and Ziony, 1985). In Mineral and Esmeralda Counties, the Candelaria Formation is 3,200 feet thick and composed of shale with lesser to equal amounts of sandstone and minor limestone and conglomerate (Ross, 1961, Albers and Stewart, 1972); in northern Nye County, the Candelaria Formation at Willow Spring is reported to be mostly argillite and siltite with minor limestone and quartzite (Kleinhampl and Ziony, 1985). Argillite is included with siltstone in the lithology coding.
