自1965年以来,我们在辽东地区几个金的成矿带上,以Au为直接指示元素,以Cu、Pb、Ag、As为辅助元素,用分散流、次生晕、原生晕等手段与地质相配合,进行了地球化学找矿工作.先后投入1/5千的30公里~2、1/万的200公里~2、1/2.5万的1200公里~2的次生晕工作和1/2.5万的400公里~2的分散流工作.由试验、试睑性生产到大面积投产,都取得了一定的地质效果.并对金在表生环境中的变化,不同类型金矿床中次生晕成晕特征,异常推断解释和评价方法,以及金的直接指示作用等,有了初步认识.
Since 1965, we have used Au as the direct indicator element in several gold metallogenic belts in the Liaodong area. With Cu, Pb, Ag and As as auxiliary elements, we use the means of dispersive flow, secondary halo and primary halo Geological cooperation, conducted a geochemical prospecting work has invested 1/5 thousand 30 km ~ 2,1 / 200 200 km ~ 2,1 / 25 000 1200 km ~ 2 secondary halo work and 1 / 25000 distributed flow of 400 km ~ 2 work.From the test, test the production of the eyelid to a large area production, have achieved some geological effects.And the gold in epigenetic environment changes, different types of gold deposits in the secondary Halo Halo characteristics, anomalous inferred interpretation and evaluation methods, as well as the direct indication of the role of gold, with a preliminary understanding.
