The Baishipo Ag deposit, located in Luoshan County of Henan Province, is an important silver deposits related to Mesozoic magmatism temporal-spatially and genetically. A U-Pb age of zircons (140.6Ma) from the ore-bearing granitic porphyry in the Baishipo silver deposit, dated by the SHRIMP II method, indicates that the ore-bearing granitic rocks formed at the same stage of a regional granitic batholith. That means the silver mineralization might happen in the Mesozoic and have a genetic relationship with granitic magmatism. All of the porphyry-type Mo deposits, epithermal-type Au-Ag deposits and bentonite deposits can be classified as a metallogenetic subseries of mineraldeposits originally related to Mesozoic magamtism.
