| 中文摘要: |
| 以航空高光谱遥感数据(CASI/SASI/TASI)为基础,通过对花牛山地区的高光谱矿化蚀变信息及其矿物组合的研究,分析了矿化蚀变与铅锌矿成矿的关系,总结了花牛山铅锌矿床的高光谱遥感特征,并对矿区周边进行成矿预测。研究认为花牛山铅锌矿床的标志性蚀变矿物组合为硅酸盐类矿物+褐铁矿化+贫铝绢云母化,具有上述标志性蚀变矿物组合的印支期花岗岩(枝)与震旦系洗肠井群第三岩组地层接触部位,是寻找与花牛山铅锌矿床类型相近的多金属矿床的有利地区。 |
| 英文摘要: |
| Based on airborne hyper-spectral remote sensing data (CASI/SASI/TASI), the metallogenic relationship between alteration and Pb-Zn mineralization was analyzed by the study of mineralized alteration information and mineral assemblages that extracted from hyper spectral data in the Huaniushan Pb-Zn deposit area. Then the hyper-spectral remote sensing characteristics was summarized and the favorable prospecting targets were predicted in the surrounding area. The study result suggests that the landmark alteration mineral assemblages in the Huaniushan Pb-Zn deposit area is silicate minerals + limonitization + aluminum-poor sericitization. The contact area between Indosinian granite intrusion and the 3rd formation of Sinian Xichangjing Group where the landmark alteration mineral assemblages occur, is mostly favorable area for prospecting polymetallic metals deposit similar to the Huaniushan Pb-Zn deposit. |
