摘要 围山城成矿带是我国重要的变质碎屑岩型金银成矿带之一,矿带西部有破山大型银矿,中部有银洞坡特大型金矿,新发现的老洞坡-河坎银矿位于其东端,构成围山城金银矿带。矿带普查初期,曾系统开展过万分之一土壤及岩石地化测量,二者的工作方法虽然不同,但异常的形态、强度、规模、连续性、渐变性以及异常与矿体(带)的关系均大同小异,显示二方法所取得的地质效果基本一致。 The Weishancheng metallogenic belt is an important bullion metallogenic belts developed in the metamorphic clastic rocks in our country. It is composed of the following three parts: Poshan silver deposit in its west part, Yingdong gold deposit in its middle and the newly discovered Laodongpo - Hekan silver deposit in the east. Soil and rock geochemical exploration with the scale of 1/10,000 were carded out in the initial reconnaissance. The results can be cross proved in the shape, intensity, scale, connectivity and changing direction of the geochemical abnormalities and their relationship with the ore bodies. The above results indicate that the effects of soil and rock geochemical exploration are almost identical.
