Division of Metallogenic Unit in the Qinling Area

Metallogenic unit is a geological unit on thein terms of metallogenic significance.The latest classification scheme about Chinese metallogenic units released by the national mineral resource potential assessment project includes Level I(Metallogenic domain),Level II(metallogenic provinces)and Level III(metallogenic belts).This article revises boundaries of the five Level III metallogenic units(metallogenic belts)in the Qinling area on the basis of the inheritance of this previous classification scheme.Then the five Level III metallogenic units are divided into 15Class IV metallogenic units(metallogenic sub-zones))as a symbol of according to significant stratigraphic,tectonic and magmatic belt characteristics and as well as relevant majorassociated mineralization.Furthermore,there is a summary about geology and mineral characteristics features of every Class IV metallogenic unit(metallogenic sub-zones)are summarized in this paper.
