| 摘 要： | 东准噶尔顿巴斯套金矿床L8号矿体为区内主矿体之一,对其开展钻孔原生晕测量工作并建立正确的找矿模型,能够为矿区深部及外围找矿预测提供依据。选取0线、8线、7线及11线等对L8号矿体控制程度较高的勘探线剖面为研究对象,对剖面上揭穿该矿体的钻孔进行了系统采样和分析。结果表明,0线、8线及7线、11线原生晕轴向分带系列分别为Mo-Cu-Au-As-SbAg-Zn-Hg-Co-Pb和Hg-Zn-Mo-As-Au-Ag-Pb-Cu-Co-Sb。建立了L8号矿体的原生晕叠加模型,认为矿体在7线和11线、0线和8线都有一定程度的向下延伸趋势,但在0线和8线的延伸程度比7线和11线差,据此建议后期找矿工作应在7线、11线800m以下标高进行。上述认识得到了后期工程的验证。

| Abstract: | The ore-body No.L8 of Dunbasitao gold deposit is one of the most important ore-bodies in this area.By analyzing its primary halos characters and establishing the model of the overlapped primary halos,it can provide some valued evidence for the deep prospecting.This paper chooses the No.0,No.8,No.7,and No.11 exploration lines and sampling where the drill exposed the ore-body.It is resulted that the sequence of No.0and No.8exploration lines and No.7and No.11 exploration lines are Mo-Cu-Au-As-SbAg-Zn-Hg-Co-Pb and Hg-Zn-Mo-As-Au-Ag-Pb-Cu-Co-Sb.It shows that the ore-body both extends into the deep at the No.0,No.8,No.7and No.11 exploration lines,but it may extend deeper at the No.7,No.11 than the No.0,No.8exploration lines.It is advised the later exploration work should at the depth of lower than 800 min the No.7and No.11 exploration lines.In addition,the later exploration engineering had verified the opinions above. |
