Revised stratigraphic nomenclature for parts of the Ediacaran-Cambrian Series 2 succession in the southern Great Basin, USA

Mixed carbonates and siliciclastics assigned to the Reed, Deep Spring, Campito, Poleta and Harkless formations of eastern California and western Nevada, USA, comprise one of the most complete stratigraphic successions across the Ediacaran-Cambrian Series 2 interval known in North America. Distinctive, widely mappable members, mostly informal, have long been recognised for each of the formations. New, formal lithostratigraphic names are proposed for members of the Deep Spring Formation (Dunfee, Esmeralda and Gold Point members) and the Harkless Formation (Weepah and Alkali members).
