| 摘 要： | 三道湾子金矿位于大兴安岭燕山期成矿带东南部, 是近年来新发现的典型的石英脉型金矿床。通过在该矿床土壤中进行的金元素富集层位及粒度试验, 确定B2层为土壤测量的取样层位和-40目为样品加工粒级, 圈定Au、Ag、As、Sb异常多处, 各元素异常浓集中心与已知金矿体吻合较好。经过对异常验证, 发现了新矿体, 扩大了矿床规模, 土壤测量在该区找矿效果显著。

| Abstract: | Located in the southeast of Da Hinggan Ling Yanshannian metallogenic belt,the Sandaowanzi gold deposit is a typical quartz vein gold deposit discovered in recently years.Based on sampling method tests(sampling horizon and size fraction experiments),it is known that the optimal sampling horizon is B2 soil and the best sampling size fraction is-40 mesh grain size.Through applying the method to soil survey,some Au,Ag,As and Sb anomalies were delineated,and several new gold orebodies were found.The centers of the anomalies coincide with the gold orebodies.The effects of oil survey are fairly good. |
