Title: Middle Cambrian Section in Vicinity of Currant Creek, Nevada: ABSTRACT

Author(s): William W. Lumsden, Takeo Susuki

Article Type: Meeting abstract

Abstract:

A regional study of the White Pine Range, eastcentral Nevada, has disclosed in the vicinity of Currant Creek a previously undescribed Middle Cambrian section. Approximately 4,000 feet of strata composed dominantly of thin-bedded limestone and shales, lies directly above the Lower Cambrian Prospect Mountain quartzite, and below the Upper Cambrian Dunderberg formation.

Though faulted, the section has yielded rich trilobite faunas representing in ascending order the Middle Cambrian zones: Albertella, Glossopleura and Bathyuriscus-Elrathina. The Bolaspidella zone may be present but is not recognizable because of structural complexities and scarcity of fossils.

The Currant Creek section has been compared with that of the Pioche District, Nevada; House Range, Utah; and the Bear River Range, Utah-Idaho. Comparisons indicate that the Albertella zone of Currant Creek is similar to that of the Upper Pioche shale, Highland Peak Range, and the Naomi Peak limestone member of the Langston formation, Bear River Range. The Glossopleura zone is particularly well-developed in the Currant Creek section and the faunal assemblage is remarkably similar to that of the Spence shale of the Bear River Range. It may represent a westward extension of the extracratonic faunal environment postulated for the Spence shale and Langston limestone.
