Thermochemical sulphate reduction and Huayuan lead-zinc ore deposit in Hunan, China

摘要

In recent years, some arguments with regard to the organic mineralization of MVT lead-zinc ore deposit are focused on thermochemical sulphate reduction in the presence of organic matter. Based on the research into the organic geochemistry and C,O,S isotopes of min- eralized host rocks, mineral gas fluid inclusion and solid bitumen from Huayuan (W.Hunan, China) lead-zinc ore deposit formed in the algal limestones of Qingxudong formation, Lower Cambrian, the authors consider that a lot of organic matter occurred and participated in mineralization.
