烟筒桥子金矿床隐爆角砾岩成因与隐爆机制

Petrogenesis and crypto-explosive mechanism of cryptoexplosive breccia in Yantongqiaozi gold deposit

烟筒桥子金矿床位于吉林省梅河口市水道镇,大地构造位置属于中朝准地台(Ⅰ),辽东台隆(Ⅱ),铁岭—靖宇台拱(Ⅲ),龙岗断块(Ⅳ)中段北缘,为一典型的隐爆角砾岩型金矿床。矿体在空间和成因上受控于爱林西山隐爆角砾岩筒。笔者通过近几年的地质工作,浅谈该区隐爆角砾岩体的地质特征、成因和隐爆机制。

Yantongqiaozi gold deposit is located in Shuidao Town of Meihekou City, Jilin Province. The geotectonic location belongs to northern margin in the middle section of Sino-Korean paraplatform（I）, Liaodong platform uprise（Ⅱ）, Tieling-Jingyu anteklise（III）, Longgang block（Ⅳ）. Yantongqiaozi gold deposit is a typical cryptoexplosive breccia type gold deposit. The space and genesis of the deposit were controlled by cryptoexplosive breccia in west hill of Ailin. Through the geological work in recent years, the authors discussed the geological features and the genesis of cryptoexplosive breccia and cryptoexplosive mechanism in this area.
