    The geology of Arizona began to form in the Precambrian.Igneous and metamorphic crystalline basement rock may have been much older, but was overwritten during the Yavapai and Mazatzal orogenies in the Proterozoic.The Grenville orogeny to the east caused Arizona to fill with sediments, shedding into a shallow sea. Limestone formed in the sea was metamorphosed by mafic intrusions.

    Stable Cd isotopic compositions of Ediacaran-age carbonates from the Xiaofenghe section on the Yangtze Platform show significant variations of up to four ε 112/110 Cd units. There are several possible reasons for these variations: part of the signal may be biological in origin while abiological (inorganic) processes almost certainly play a role as well.
