摘要
为预测湖南临湘虎形山钨矿床主矿体的深部变化趋势,在矿床地质特征和矿床成因研究的基础上,开展了野外地质调查和原生晕地球化学研究。微量元素统计分析表明,矿体的前缘晕元素为Ag、Zn、Au、Pb、Be、As、Cu,近矿元素为W、Bi,尾晕元素Sb、Sn、Mo。24号勘探线的钻孔原生晕数据表明,矿体自上而下其原生晕轴向分带序列为:Ag-Zn-Au-Pb-Be-As-Cu-W-Bi-Sb-Sn-Mo,具有"头尾晕共存"和"反分带"特征。结合矿体原生晕轴向分带模式,预测矿体向深部(-350 m以下)有一定的延伸或深部有盲矿体的存在。
In order to predict the extending change trend of main ore bodies to the depth in the Huxingshan tungsten deposit,on the basis of analyzing geological features and genesis of the deposit,a further field geological survey and research on geochemical characteristics of primary halos of the deposit have been carried out in this paper.The statistical analysis of contents of trace elements shows that the front halo elements of the orebody are Ag、Zn、Au、Pb、Be、As、Cu,the near ore halo elements are W、Bi,and the tail halo elements are Sb、Sn、Mo.The primary halo data of drill core samples from boreholes in the No.24 exploration line show that the axial zoning sequence of primary halo of the ore body from top to bottom is Ag-Zn-Au-Pb-Be-As-Cu-W-Bi-Sb-Sn-Mo,with characteristics of"the coexistence of front and tail halos"and"the reverse zoning".Combined with the primary halo axial zoning model of the orebody,it is predicted that there could be a certain extension of the main orebody or a blind orebody in depth below-350 m in elevation in the deposit.
