| 摘 要： | 广西隆安县凤凰山银矿床位于寒武系黄洞口组，赋矿岩石为一套具复理式建造特征的浊流沉积暗色细碎屑岩。矿体受近东西向的断裂破碎带控制。通过地质特征和氢氧、硫、铅同位素地球化学特征及包裹体特征、成矿温度的研究，认为银矿的成矿物质主要来自寒武系地层；成矿热液以大气降水为主，有深部热液的参与；成矿温度为低—中温

| Abstract: | Fenghuangshan silver deposit of Guangxi Long'an county lies in Huangdongkou formation of cambrian system. The ore-preserving rock is a series of dark-colored fine-clastic rock of turbidity current deposit with the feature of flynch formation. The ore-body is controlled by a nearly east-west striking shattered fault zone. Through study on its geological feature, geochemical characteristics, H, O, S and Pb isotopes , inclusion feature and mineralization temperature, the authors consider that the metallogenetic material mainly comes from the strata of cambrian system, the metallogenetic hydrothermal fluid mainly is meteoric water being participated by hydrothermal water from deep part, and the mineralization temperature is epithermal to mesothermal. |
