冀北小寺沟铜钼矿外围银金资源潜力浅析

STUDY ON THE Ag-Au MINERAL RESOURCE POTENTIAL IN THE SURROUNDINGS OF XIAOSIGOU Cu-Mo DEPOSIT IN THE NORTH HEBEI PROVINCE

小寺沟周边地区成矿地质条件十分优越,与燕山期中晚期陆相潜火山作用有关的多金属矿化广泛发育。在岩体内产有中大型规模的斑岩型铜钼矿床。近年来在其外围新发现一批银、金多金属异常,经初步评价已发现一具中型以上规模的银金矿床。本区具有系列成矿特征,银金资源潜力较大。

The surroundings of Xiaosigou Cu-Mo deposit is superior in metallogenic conditions. Poly-metal mineralization realted to Middle-Late Yanshanian sub-volcanics is widely developed. Large-medium size porphyric Cu-Mo deposits occur in the intrussive bodies. In recent years a series of Ag-Au-poly-metal anomly have been located. The primary assessment of the anomlies leads to discovery of a medium size Ag-Au deposit thus the surroundings is characteristic of serial metallogenesis and big Ag-Au resource potential.
