湖南省稻草湾锑矿矿床成因及找矿前景分析

Analysis of Metallogenic Factors and Prospecting Potentiality of Sb Deposit in Straw Bay,in Hunan Province

稻草湾锑矿位于湘中涟源盆地的南缘,城步—桃江成矿带上。通过对矿床成因中含矿物质来源及含矿热液运移等方面的分析研究,认为矿区锑矿具有中低温热液成因、"背斜+断裂"及"含矿硅化灰岩+页岩覆盖"控矿特征,初步建立了成矿模式,验证了本区存在北东向控矿构造与东西向构造交汇部位联合控矿的规律,且工作区内存在类似构造配套较多,显示出较好的找矿前景。

Straw Bay Sb deposit is located in the Chengbu-Taojiang Metallogenic Belt,the southern edge of the Lianyuan basin.By analyging and studying the mineral source and the migrating direction of mineral liquid,we summarized as follows:the mineralization in the area is controlled by the anticline and fracture,as well as shale,which overlies on the mineralized-silicated limestone;the deposit is medium-low hydrothermal genesis;furthermore we have built the metallogenic model and confirmed that the area has a regularity that the confluence of NE and EW ore-controlling structure controls the mine.Because of many similar structures,the area has well prospecting potentiality.
