Study on Metallogenic System and Metallogenic Model of Tungsten-Tin Polymetallic Deposit in Dengfuxian Ore Concentrated Area,Eastern Hunan Province
The Dengfuxianore concentrated area in the northeast of ChalingCounty,Hunanprovince,is locatedin the Southwest section of the Qinzhou-Hangzhou Junction,the eastern part of the Nanling metallogenic belt.The tectonic position is at the junction of southern Gannan Uplift and Xiang-gui depression.Mineral resources are abundant in the area,and rare metal deposits such as tungsten,tin,lead,zinc,niobium and tantalum are developed.Typical deposits include Xiangdong tungsten deposit(also known as Dengfuxian tungsten deposit),Jinzhulang niobium-tantalum deposit,Jiguanshi tungsten deposit,Dagang lead-zinc deposit,Taihexian lead-zinc deposit,all of which are post-magmatic hydrothermal mineralization,mineralization potential is huge,and form a complete high-medium-low temperature hydrothermal metallogenic series.Based on the studying the geological characteristics,physical and chemical conditions of the ore deposit,the source of ore-forming material and fluid,the ore-forming age,the ore-forming process and the genesis of the ore deposit,the metallogenic system and metallogenic model of the ore concentration area were established,whichhas the practical significance toguide the deep and side prospecting of the same ore deposit in this area.
