微细浸染型金矿是形成大型—超大型金矿床的主要类型之一。镇旬盆地位于扬子板块被动大陆北缘南秦岭局限海盆，广泛发育一套早古生代—中生代碳酸盐岩夹细碎屑岩沉积，盆地构造演化复杂，伴随着大量岩浆、流体和热液成矿作用的不断发生。在前人研究成果的基础上，结合野外实际工作，综合分析了镇旬盆地构造演化、岩相古地理、构造动力、古陆远程成矿、区域地层和生物成矿作用等条件，认为镇旬盆地是大型—超大型微细浸染型金矿的远景区之一。

It is o ne 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.
