摘要
Based on comprehensive analyses, the metallogenic setting, tectonic evolution, major deposit types, regional metallogenic rules and series in this area are described briefly in this paper. This area underwent four tectonic cycles including Precambrian old land formation, early Paleozoic orogenic activity, Late Paleozoic-Early Mesozoic orogenic process and Cenozoic overlap orogenic process. Of these, early Paleozoic and Late Paleozoic-Early Mesozoic orogenic activities were related genetically to metallic mineralization.Six types of deposits are recongnized. The metallic mineralization is characterized by multiperiod, multi-elements and multistyles.
