Upper Pennsylvanian to Lower Permian strata were studied in Carlin Canyon, Nevada. Twelve sections were measured in outcrops and sampled for lithological and conodont biostratigraphic analysis. Microfacies analysis yielded 12 microfacies representing a ramp. The late Gzhelian lower Strathearn Formation contains a series of glacio-eustatic cyclothems that constitute a third-order sequence. Its interpreted paleoenvironment is warm-water ramp with varying sub-environments. The mid-upper Asselian upper Strathearn Formation contains clean carbonates that represent a deeper water ramp associated with a very shallow thermocline, and represents a third-order sequence. The Sakmarian lower Buckskin Mountain Formation contains deposits representative of an outer ramp setting; it is part of a transgressive systems tract. The middle Buckskin Mountain Formation is Artinskian; it represents a regressive systems tract and comprises coarse grained carbonates, of inner to mid ramp setting associated with a shallow thermocline. A middle to late Asselian cooling trend is observed in Carlin Canyon.
