| 摘 要： | 贵州西部Pt、Pd异常是川滇黔铂钯地球化学巨省的一部分,在威宁东部和水城南部地区存在2个异常强度规模大、结构模式理想的铂钯地球化学省。贵州西部发育NW向的断陷裂谷构造,分布有数个古火山口,构成了玄武岩浆喷溢活动通道,提供了Pt、Pd、Cu等多金属成矿物质来源和成矿条件,可望找到一定规模的铂钯矿床。本区可能存在一种新的铂钯矿床类型：受裂谷环境古火山口相峨眉山玄武岩顶部假整合面控制的同生火山热液叠加改造型铂钯铜矿床;此外还有可能存在构造热液型铂钯矿、红土型砂铂矿等类型。要取得在该区发现铂钯矿床的突破性进展,需要持续大量有效的勘查投入。

| Abstract: | Pt-Pd anomaly in west Guizhou is one part of Pt-Pd geochemical region of Sichuan,Yunnan and Guizhou. There are two Pt-Pd geochemical areas with intensive anomaly and large scale and ideal anomaly pattern in east Weining and south Shuicheng. Rifting structure in NW is located in west Guizhou with some ancient craters. They constitute of the chunnel of basalt magma effusion and provide mineral source. It is hoped to find Pt-Pd deposit of a certain scale. There is probably a new type Pt-Pd deposit,Pt-Pd-Cu deposit of syn-volcanic hydrothermal reconstruction in discomformity of the top of Emeishan basalt of ancient crater face in the rifting environment,in west Guizhou. Moreover there might be Pt-Pd deposit of structural hydrotheraml type and laterite Pt deposit. It is necessary to provide a great deal of effective exploration investment in order to obtain prospecting breakthrough in the west Guizhou. |
