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 15 Class 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.
