| 摘 要： | 龙脖河铜矿带老新街铜矿床位于红河断裂与阿龙古—龙山断裂夹持的红河裂陷槽中。矿体呈层状、似层状产出，受层位、岩性和构造控制。围岩蚀变发育，硅化、黄铁矿化、绿泥石化与矿化关系密切。根据老新街铜矿床的地质特征，探讨了成矿物质来源和成矿机制，指出了矿床属于火山喷流沉积－ 热液叠加改造型层控矿床

| Abstract: | The Laoxinjie copper deposit in Longbohe ore belt, Yunnan, is located in Honghe River rifting trough bounded by Honghe River fault and Alonggu-Longshan fault. The orebodies, as stratiform and stratoid, are controlled by strata, lithology and structure. The mineralization has close relation to thermal alteration characterised by silicification, pyritization and chloritization. Based on the geological characteristics, its metallogenesis is inquired into. It is suggested that it is a stratabound deposit formed by exhalative sedimentation and hydrothermal superimposition ( and or reworking). |
