内蒙古白音查干银多金属矿床是近年来在大兴安岭中南段西坡最重要的多金属找矿新发现,具有成为大型银多金属矿床的潜力。通过矿床原生晕研究,确定矿床元素轴向分带序列(自上而下)为:Mo-F-As-Sb-Hg-B-Au-Bi-Cu-Ag-Pb-Zn-Cd-P-Ni-Co-Fe-W-Sn,提出(As×Hg)/(W×Sn)元素累乘比值可用来判断矿体剥蚀状况,并应用此比值预测I-0勘探线-500m以下发现的盲矿体向深部有很大的延伸,预测结果在进一步勘探中得到证实。
The Baiyinchagan silver polymetallic deposit in Inner Mongolia is the most important polymetallic prospecting discovery on the western slope of the Daxinganling Mountains in recent years and has the potential to become a large silver polymetallic deposit. According to the study of primary halo of the deposit, the axial zonation sequence of the ore deposit element is determined from top to bottom: Mo-F-As-Sb-Hg-B-Au-Bi-Cu-Ag-Pb-Zn-Cd-P- Ni-Co-Fe-W-Sn, the (As × Hg) / (W × Sn) element accumulation ratio can be used to judge the ore body denudation condition and this ratio is used to predict the blindness found in the I-0 exploration line below -500 m The ore body extends greatly to the deep and the prediction result is confirmed in further exploration.
