| 摘 要： | 那陵郭勒河西地区处东昆仑祁漫塔格成矿带,成矿地质条件优越。但该地区为荒漠戈壁景观,地表无岩石、矿化出露,覆盖较厚,一般为150～300m。通过高精度磁法测量并对磁异常钻孔验证,在深部发现较好的铁多金属矿体,初步了解了地质特征。铁多金属矿为矽卡岩型矿床,磁法工作在该地区取得了较好的效果。

| Abstract: | The iron-polymetallic deposit in West Nalinggele River of Qinghai belongs to the Qimantage metallogenic belt in the western section of east Kunlun Mountain, and with favorable ore-forming condi- tion. Due to the Gobi desert landscape and thick cover, usually 150-280 m in this region, there is no rocks and mineralization exposed. Through the high-precision measurement of magnetic and magnetic anomaly drilling authentication, the good iron-polymetallic ore bodies are found in the deep. The preliminary un- derstanding of the geological features indicate that the iron-polymetallic deposit belongs to the skarn-type deposits, and this also means that the magnetic work in the region has achieved good results. |
