| 中文摘要: |
| 青海哈得尔甘地区地处东昆仑西段祁漫塔格山东部,平均海拔4300m,地形切割深,山势陡峭,河谷深切,基岩裸露,植被稀疏,具有较好的遥感地质找矿条件。选用ETM+多光谱数据,通过遥感数据预处理,获取基础遥感影像,并从中解译出地层岩性、侵入岩体和线、环状构造,建立解译标志。结合区内成矿地质背景,根据遥感地质异常特征,进行遥感地质找矿预测研究,圈定出8处遥感异常区,并从中优选出3处遥感异常区作为优先验证的找矿靶区,可为研究区铜铅锌多金属矿和稀有土矿找矿工作提供有利指导。 |
| 英文摘要: |
| The Hadergan area of Qinghai is located in the eastern part of Qimantag Mountain in the western part of East Kunlun, with an average elevation of 4300 m, deep terrain cuts, steep mountains, deep valleys, bare bedrocks, and sparse vegetation. It has good remote sensing geological prospecting conditions. Landsat 7 (ETM +) multispectral data was selected, and basic remote sensing images were obtained through preprocessing of remote sensing data, and the lithology, intrusive rock masses, and line and ring structures were interpreted from them to establish interpretation marks. Based on the geological background of mineralization in the area, and based on the characteristics of remote sensing anomalies, a remote sensing geological prospecting study was carried out. Eight remote sensing anomaly areas were delineated, and three remote sensing anomaly areas were selected as the prospecting target areas for priority verification. The area's geological prospecting work provides favorable guidance. |
