Abstract:

It is one of the main types of large and super-large gold deposit for the micro-disseminated gold deposit.Zhen’an-Xunyang basin is located in the northern margin of the Yangtze plate passive continent,and belongs to limited Basin of southern Qinling Mountains.It widely develops a set of carbonate and fine clastic rocks during early Paleozoic-Mesozoic.The tectonic evolution is very complex,and accompanied by a large number of magmatic mineralization,fluid mineralization and hydrothermal mineralization.Based on the collection of previous research results and the field work comprehensive,we analysis the tectonic evolution,lithofacies palaeogeography,tectonic dynamics,the remote mineralization,regional strata and biological mineralization of the Basin.It is concluded that the Zhen’an-Xunyang Basin is one of prospecting area for the large and super-large micro-disseminated gold deposits.

Key words: micro-disseminated gold deposit, metallogenic conditions, Zhen’an-Xunyang Basin, southern Qinling Mountains
