黑龙江团结沟金矿区花岗斑岩体与金矿化的关系

The relation between gold mineralization and granite porphyry mass of TuanJieGou Gold Field,Heilongjiang Province

团结沟金矿区花岗斑岩为岩株状产出的浅成超浅成侵入体。斑岩体内有两期矿化；早期发生在隐爆角砾岩带内，呈环形分布；晚期发生在北西西、北北西构造带内。斑岩体不仅提供成矿热液，也提供部分矿质。

The granite porphyry occurred in TuanJieGou Gold Field is rock plant like hypabyssal/super hypabyssal intrusive mass.Two phases of mineralization took place in porphyry mass.The early phase of it took place in the belt of concealed explosive breccia presenting ringlike distribution while the later phase of it happened in the northwest by west/northwest by north structural belt.The porphyry mass provided not only mineralizing hydrothermal solution but also a part of mineral matter.
