摘要
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。
Bayanchagan silver polymetallic mine,Inner Mongolia is an important newly-discovered mine which is finding in the western slope of south area of Daxing Anling metallogenic belt.The mine is explorating now.And it maybe become a large-sized silver polymetallic mine.By the research of the miner halo,setting up geochemical axial direction zonation se-quence is (from up to down):Mo-F-As-Sb-Hg-B-Au-Bi-Cu-Ag-Pb-Zn-Cd-P-Ni-Co-Fe-W-Sn.The ratio of (As×Hg)/(W×Sn)can infer denudation degree of the orebody.And with the ratio of (As×Hg)/(W×Sn)infers that the buried orebody of I-0 profile blow -500 meter extending very far to deep.The inferring result is proved by the further exploration.
