| 摘 要： | 紫金山矿田隐爆角砾岩发育,矿床与隐爆角砾岩有着紧密的关系。二庙沟矿区位于紫金山矿田西部,区内隐爆角砾岩零星出露。本文以二庙沟金子湖旁的隐爆震碎角砾岩为主要研究对象,通过隐爆角砾岩的分布特征、二庙沟金子湖旁周边的矿物蚀变组合特征及金子湖周边裂隙的特征分析,提出二庙沟矿区内金子湖附近为火山机构及隐爆角砾岩活动中心。该隐爆角砾岩中心的厘定,对该矿找矿勘查有一定的指导意义。 |
| 关 键 词： | 隐爆角砾岩 火山机构 隐爆中心 二庙沟 |

| Abstract: | Cryptoexplosive breccia,which is closely associated with Cu-Au-Mo-Pb-Zn mineralization,is well developed in the Zijin epithermal-porphyry ore field.Cryptoexplosive breccia is found locally in the Ermiaogou ore region that is located in the west part of the Zijin ore field,cropping mainly in the nearby domain of the Jinzi lake.Based on the distribution of shatter breccia and breccia diameter increasing from the center outwards of the Jinzi lake,the occurrence of the fractures around the Jinzi lake,the alteration mineral assemblage varying from kaoline to illite from the center outwards of the Jinzi lake,and landscape around the Jinzi lake in the Ermiaogou ore region in the Zijin ore field,it is concluded that a volcanic edifice and the related cryptoexplosion center was located in the vicinity of the Jinzi lake.Thus,ore prospecting should focus on the area near the Jinzi lake. |
| Keywords: | cryptoexplosive breccia volcanic edifice center of cryptoexplosion Ermiaogou |
