| 中文摘要: |
| 金坑矿区受区域性动力变质作用影响产生长约1400 m,宽约700 m的矿脉带,形成了铜锡铅锌多金属矿床。为弄清动力变质构造蚀变带特征与成矿关系,通过野外各种地质现象及掌握的第一手资料对矿区矿体特征及蚀变特征进行分析研究,认为动力变质构造蚀变带由于动力变质作用强弱、蚀变类型及强度的差异形成了弱片理化硅化带—强片理化、糜棱岩化、绿泥石化石榴石化带—片理化、硅化、绿泥石化带—弱片理化、千枚岩化硅化带等分带,各分带与矿化种类、矿化强弱有着密切的关系。 |
| 英文摘要: |
| Due to the regional dynamic metamorphism in the Jinkeng gold deposit area, one Sn-Cu-Pb-Zn polymetallic mineralization vein zone was formed with a length of 1400 meters, and width of approximately 700 meters. For understand the dynamic metamorphic tectonic alteration zone characteristics and metallogenic relationship, through all kinds of field geological phenomena and grasp first-hand data of orebody characteristics and corrosion variable analysis and study on the characteristics, that the dynamic metamorphic and tectonic alteration zone due to differences in the type and strong dynamometamorphism strength, corrosion degree formed weakly foliated silicified zone-strong schistosity and mylonitic, green mud Petrochemical pomegranate Petrochemical band schistose alteration, silicification, chloritization Petrochemical with weak schistosity, thousands of phyllite silicide with equant belt, each with and mineralization types, mineralization intensity has a close relationship. |
