贵州维寨锑矿床辉锑矿矿物学研究及其地质意义
|
摘要
独山县维寨锑矿位于扬子陆块与华南褶皱带交接的过渡地带中。文章在野外地质调研的基础上,进行辉锑矿电子探针及X衍射分析研究,结果表明辉锑矿的化学成分较为单一(Sb,S含量分别为70.35%~71.54%和27.36%~28.36%),晶胞参数分别为:WZ01 a_0=1.124,b_0=1.132,c_0=0.384;WZ02 a_0=1.122,b_0=1.131,c_0=0.384;综合研究认为丹林群(D_1d)及翁项群(S_(1-2)wn)为维寨锑矿主要赋矿层位,NWWNW向断裂为该区的主要控矿构造,维寨锑矿床属于低温热液充填型锑矿床。
Weizhai antimony deposit in Dushan county is located in the transition zone of Yangtze landmass and south China folds. Base on field geological investigation,stibnite electronic probe and X-ray diffraction analysis was conducted. The results showed that the chemical composition of the antimony was relatively single( Sb,S content was respectively 70.35% ~ 71.54% and 27.36% ~ 28.36%,),and the cellular parameters were WZ01: a_0= 1.124,b_0= 1.132,c_0= 0.384; WZ02: a_0= 1.122,b_0= 1.131,c_0= 0.384. Comprehensive research show that the Danlin group( D_1d) and Wenxiang group( S_(1-2)wn) are the main ore-bearing layers in the area,NWWNW fault is the main ore-controlling structure and Weizhai antimony deposit is the type of low-temperature hydrothermal filling deposit.
