Named for Zabriskie Point

The Zabriskie Quartzite is a Cambrian Period geologic formation of the northern Mojave Desert, in Inyo County, California and Nye County, Nevada. [2] [3]

Contents

It is named for its occurrence at Zabriskie Point, located on the eastern slopes of Death Valley in Death Valley National Park. [2]

Geology

The lower unit is defined by the Resting Springs Member, the upper unit by the Emigrant Pass Member. [3]

It overlies the Wood Canyon Formation, and underlies the Carrara Formation. [4]

The Quartzite is mostly massive arid granulated due to shearing, in beds 0.5–2 feet (15–61 cm) thick within the park, [2] and up to 984 feet (300 m) elsewhere. [4]

Paleobiota

The Zabriskie Quartzite contains a wealth of Skolithos trace fossils, although no other fossils have been reported from this formation, despite the underlying and overlying formations containing fossil material. [1]
