Cambrian and Neoproterozoic
Includes the following units of Ross (1963, 1965, 1967) and Stewart (1970): Cambrian Tamarack Canyon Dolomite (thin-bedded dolomite with chert nodules in basal part); Cambrian Lead Gulch Formation (limestone, siltstone, shale, and chert); Cambrian Bonanza King Formation (generally fine-grained dolomite); Cambrian Monola Formation (upper member is limestone with interbedded siltstone and shale; middle member is massive limestone; lower member is siltstone and silty limestone); Cambrian Mule Spring Limestone (thin- to medium-bedded limestone); Cambrian Saline Valley Formation (upper member is siltstone and quartzite, lower member is siltstone and minor sandstone overlain by thin-bedded limestone); Cambrian Harkless Formation (silty shale with interbedded quartzite); Cambrian Poleta Formation (upper member is shale, limestone, and quartzite; lower member is massive limestone); Cambrian and Neoproterozoic Campito Formation (upper member is shale and interbedded sandstone and siltstone; lower member is massively bedded quartz sandstone and interbedded siltstone and shale); Neoproterozoic Deep Spring Formation (upper member is sandstone and siltstone overlain by dolomite and limestone; middle member is quartzite overlain by interbedded limestone, sandstone, and shale; lower member is limestone with minor interbedded dolomite, sandstone, and shale); Neoproterozoic Reed Dolomite (massive fine-grained dolomite over a tongue of interbedded quartzite, sandy dolomite, and calcareous sandstone over massive coarse-grained dolomite); and Neoproterozoic Wyman Formation (argillite, sandstone, and siltstone, locally phyillitic, with a lenticular member of limestone).
