Summary:

Unit is named the Fenstermaker Wash Formation. Is exposed in the northern Antelope Range, NV. Is divided into a lower part, 80 to 183 m thick, consisting of medium-gray to light-brownish-gray, massive, medium- to coarse-grained, peloid-echinoderm-coral, stromatoporoid-brachiopod packstone and wackstone; a middle part, 42 m thick, consisting of pale-yellowish-orange, siliceous, laminated siltstone and claystone; and an upper part, 60 m thick, consisting of medium-gray, cross-bedded, peloid-mudlump packstone to grainstone that forms a massive cliff. Contains a fauna suggestive of intertidal, deep water, and subtidal deposition. Conformably and sharply overlies the Denay Formation; sharply underlies the Davis Spring Formation (new), representing an unconformity of considerable magnitude. Correlates temporally with the Bay State Dolomite and Devils Gate Limestone in the southern Fish Creek Range, 10 km to the east. Age is Middle and Late Devonian based of fossils [conodonts]. (B1565)
