Genesis of Huogeqi copper-polymetallic deposit in the northern margin of the North China Craton related to Orogenic-type deposit:Evidence from Fe,S,O,H isotope

摘要

The genetic controversy of the Huogeqi copper-polymetallic deposit,located in the northern margin of the North China Craton (NCC) have long affected geologists' prospecting.All orebodies of the deposit are enclosed within shear zone.The most popular exhalative-sedimentary model proposed for the Huogeqi deposit (Peng et al.,2006,2007) stresses that the deposit was deposited simultaneously with its host rocks and later underwent metamorphism,deformation and a limited degree of magmatic hydrothermal overprinting (Pi et al.,2010).
