what type of rock is quartz

Rosy quartz has a pale reddish-pink color and is often found in massive formations. It occurs in basically all mineral environments, and is the important constituent of many rocks. Famous finds include a crystal weighing 13 metric tons from Siberia. It is very common in sedimentary rocks such as sandstone and shale. Quartz has attracted attention from the earliest times; water-clear crystals were known to the ancient Greeks as krystallos—hence the name crystal, or more commonly rock crystal, applied to this variety. [51][52][53] Warren Marrison created the first quartz oscillator clock based on the work of Cady and Pierce in 1927.
