The Zabriskie Quartzite is a Cambrian Period geologic formation of the northern Mojave Desert, in Inyo County, California and Nye County, Nevada.[1][2]
It is named for its occurrence at Zabriskie Point, located on the eastern slopes of Death Valley in Death Valley National Park.[1]
Geology
The lower unit is defined by the Resting Springs Member, the upper unit by the Emigrant Pass Member.[2]
It overlies the Wood Canyon Formation, and underlies the Carrara Formation.[3]
The Quartzite is mostly massive arid granulated due to shearing, in beds 0.5–2 feet (15–61 cm) thick within the park,[1] and up to 984 feet (300 m) elsewhere.[3]
Fossils
It preserves fossils dating back to the Lower Cambrian period of the Paleozoic Era.[4]
