Abstract:In this article,Re-Os dating of molybdenites from the ore-bearing quartz vein in the Damingshan mining district and the drilling core in the Maling mining district of Guangxi Province,presents the isochron age of 95.40 Ma for Damingshan and the model age of 95.00~95.79 Ma for Maling,indicating the consistent metallogenic epochs in the two districts.The results also indicate that the mineralization in the Danchi metallogenic belt from the southern section of Damingshan ore field to the northwestern section of Dachang ore field(the metallogenic epochs of No.90 and No.100 orebodies both concentrated around 94.5 Ma) occurred in the Late Yanshan Age.Considering widespread contemporaneous mantle-derived magmatic rocks in the Danchi metallogenic belt and its regional geotectonic setting,the mineralization might be pertinent to the uprising of mantle source mass along deep faults connected with the mantle.Such the geodynamic background makes the Danchi metallogenic belt great potential for prospecting.The Damingshan tungsten deposit contains four occurrences of tungsten veins: the vertical large vein type,the slightly dipping quartz vein type,the network type and the rock mass type,forming a unique model of "four types in one deposit".It is worth noticing that much attentions should be given on the tin-multiple metals except tungsten in the Damingshan ore field and the tungsten except for the tin and zinc-lead-multiple metals in the Dachang ore field.Therefore,the model of Damingshan will give a guide for exploration in southern Hunan and southern Jiangxi.
Keywords:Damingshan tungsten deposit  metallogenic epoch  prospecting potential  Re-Os dating of molybdenite  the "four types in one position" model  Danchi metallogenic belt
