Northern Snake Range metamorphic core complex

The Northern Snake Range metamorphic core complex is a gently domed structure that forms the northern part of the Snake Range in Nevada. The metamorphic core complex consists of an upper plate of brittlely-faulted Cambrian to Permian mainly carbonate sedimentary rocks, unconformably overlain by Cenozoic volcanic and clastic rocks and separated from a lower plate of ductilely-deformed and metamorphosed Neoproterozoic to Cambrian sedimentary rocks, cut by Mesozoic to Cenozoic intrusions, by the intensely-deformed fault zone of the Snake Range Detachment (SRD).
