Zircon U–Pb and phlogopite 40Ar–39Ar age of the Chengchao and Jinshandian skarn Fe deposits, southeast Hubei Province, Middle–Lower Yangtze River Valley metallogenic belt, China

The Chengchao and Jinshandian deposits in the southeast Hubei Province are the two largest skarn Fe deposits in the Middle–Lower Yangtze River Valley metallogenic belt (MLYRVMB), China. They are characterized by NW-striking orebodies that are developed along the contacts between the Late Mesozoic granitoid and Triassic carbonate and clastic rocks.
