Triassic aulacogen in South Qinling is located between Hezuo-Tanchang-Liangdang fault and Lazikou-Zhouqu-Chengxian fault, extending eastward into Shanxi Province, westward into Qinhan Province. Traditionally, the northern margin of this fault zone is deemed as the boundary between Middle Qinling and South Qingling, along which a lot of multi-metal ore occurrences and mineralized points were discovered. The evidences of some multi-metal deposits support that the deposits in the tectonic belt mainly are fallen into metallogenetic type of brine water.
