| 摘 要： | 江浪穹隆位于扬子地台西缘,属九龙—木里铜锌多金属成矿带,江浪穹隆为区内重要的控矿构造,穹隆内发育多处矿点,找矿前景良好.在分析遥感蚀变信息提取地质依据和光谱前提的基础上,依据研究区矿化蚀变特征及蚀变矿物的特征光谱分别进行鉄化蚀变信息和泥化蚀变信息的提取,并结合前人的地质、物探、化探成果进行综合叠加分析,提出江浪穹隆成矿区的挖金沟—柏香林、打熊沟—黑牛洞、上海底—白崖子—笋叶林3个区域具良好的找矿前景.

| Abstract: | Jianglang dome is an important ore-controlling structure in Jianglang area which is the part of Jiulong-Muli Cu-Zn polymetallic metallogenic belt in the western margin of Yangtze terrane.There are many mineral deposits and mineral occurrences in Jianglang area,and the prospecting potentiality around Jianglang dome is very good.By analyzing the geological basis,spectrum characteristic and remote sensing alteration information,the paper extracts the information of the iron alteration and the soil alteration according to the feature of mineral and spectrum character of the altered mineral.Combining remote sensing information with the precursory geological,geomagnetic and geochemical research results,the paper has a comprehensive analysis and suggests that Wajingou-Boxianglin,Daxionggou-Heiniudong,Shanghaidi-Baiyazi-Sunyelin are the good prospecting areas in Jianglang dome. |
