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