香炉碗子金矿区次火山岩地质特征与金矿化的关系

The Geology Characteristic of the Hypo-Volcanic Crytoexplosion Rytoexplosion Breccias of the Xiangluwanzi Gold Zone And the Relation With the Gold Deposit

香炉碗子金矿区分布的次火山隐爆角砾岩体（脉）是由花岗质岩浆沿东西向脆～韧性剪切带上升到地壳浅部隐爆太古代基底岩石所形成，霏细岩脉与次火山隐爆角砾岩来自同一岩浆源，为同一岩浆活动不同演化阶段所形成的。次火山隐爆角砾岩体（脉）和霏细岩脉在时间上、空间上、成因上与金矿关系密切，稀土元素、微量元素、同位素等地球化学特征显示出主要成矿物质和成矿热液与次火山隐爆角砾岩、霏细岩同源，成岩与成矿是同一岩浆作用不同阶段的产物。东西向脆-韧性剪切带内次火山隐爆角砾岩体（脉）、霏细岩脉的存在是区内重要的找矿标志。

The hypo-volcanic crytoexplosion Breccia rock body （vein） is formed of granite magma , which is rise to the lower of the earth＇s crust along the east-western shear zone and exploded below the Archean fundus rock. The felstone vein and the hypovolcanic crytoexplosion Breccia rock are from the same magma source, and are formed in the different evolution stages. Both of them the affinity with the gold mineralization, the geochemistry characteristic of the lanthanon, microelement and isotope shows that the main mineralization material and liquid have the same source with them. The hypo-voleanic crytoexplosion Breccia rock body（vein） and the felstone in the east-western shear zone are the important Symbol of the exploration.
