摘　　要：腾龙金矿位于党河南山金成矿带上,是由断裂构造控制的蚀变岩型金矿。通过1︰5万水系沉积物测量,在本区圈定了AS-7综合异常,并进一步利用1︰1万岩屑测量进行解剖,发现了腾龙金异常区,经过后期工程揭露,圈定了有价值的金矿体13条。综合研究表明,勘查区金矿体走向严格受断裂控制,主矿体的延伸方向与岩屑测量圈定的综合异常长轴展布方向一致,充分证明了在该区运用化探手段找矿的重要指导作用。The Tenglong gold deposit is located in the Nanshan gold metallogenic belt of the Dang River, and is an altered rock type gold deposit controlled by the fault structure. Through the survey of 1： 50 thousand water system sediments, the AS-7 synthesis anomaly was delineated in this area, and the abnormal area of Tenglong gold was discovered by using 1： 10 thousand rock debris survey, and 13 valuable gold deposits were delineated by later engineering exposure. The comprehensive study shows that the gold ore body in the exploration area is strictly controlled by fracture. The extension direction of the main ore body is the same as that of the comprehensive abnormal long axis of the rock debris measurement, which fully proves the important guiding role of geochemical prospecting in this area.
