    华北地台北缘三种有潜力的金矿及其找矿方向

    PROSPECTING DIRECTION FOR THREE POTENTIAL GOLD DEPOSITS IN NORTH CHINA PLATFORM

    • 摘要: 华北地台北缘是我国一个巨型金成矿带。成矿作用主要受控于前寒武纪的结晶基底、区域性的深大断裂带和火山-岩浆活动。海西晚期-燕山期的构造岩浆活动是本区的最重要控矿因素。与构造岩浆活动有关的金矿类型,尤其是其中的特殊类型和新类型,具有巨大的找矿潜力。以下三种分布广泛、类型特殊、工作程度不足的金矿床会在将来的勘查工作中有更多的发现:1.浅成低温热液型金矿床(与花岗斑岩有关);2.斑岩型金矿床,矿体赋存于花岗斑岩和花岗质侵入岩中;3.与碱性岩有关的金矿床。

       

      Abstract: The northern margin of North China platform is a giant gold metallogenic belt of China.Main controlling factors of gold mineralization are Precambrian cystal basement,regional deep-fracture zones and volcano-magma activities.Late Paleozoic-Mesozoic tectonomagmatic activity is the most important factors.Tectonomagmatic activity-related gold deposit-types,especially the particular ones and new ones,will show their great potential in the future.More following widespread gold deposits will be found in the future prospecting because of their specific property and the short of work:1,epithermal gold deposits (related with granite-porphyry);2.porphyry gold deposits,ore-bodies are hosted in granite-porphyry and granite-plutons;3.gold deposits related with alkaline rocks.
