| 中文摘要: |
| 文章主要介绍遥感地质解译工作在青海查肖玛地区中起到举足轻重的作用,通过研究具宽幅红外中分辨率ETM+多光谱数据各波段的特征,提取与含羟基热液蚀变矿物相关的蚀变信息OH-遥感异常和含Fe3+矿物相关的铁染遥感异常,形成异常等级分布图,并进行遥感地质解译同时建立解译标志,圈出7处遥感异常,结合区域成矿背景及成矿条件,最终优选出铁、钨、锡等4个预测找矿靶区,为下一步找矿工作提取依据。 |
| 英文摘要: |
| This paper mainly introduces the role of remote sensing geological interpretation in the Chaxiaoma area of Qinghai. By studying the characteristics of each band with wide infrared resolution and ETM+ multispectral data, it is related to the extraction of hydroxyl-containing hydrothermal alteration minerals. Alteration information OH-remote sensing anomaly and iron-stained remote sensing anomaly related to Fe3+ minerals, forming an anomaly grade distribution map, and performing remote sensing geological interpretation and establishing an interpretation mark, circle 7 remote sensing anomalies, combined with regional metallogenic background and Under the mine conditions, four prospecting target areas are finally selected, which are the basis for the next prospecting work. |
