青海省那陵郭勒河西铁多金属矿地质特征及高精度磁法应用

Application of High-precision Magnetic Survey in the Exploration of the Iron-polymetallic Deposit in West Nalinggele River of Qinghai, and Its Geological Characteristics

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 condition.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 understanding 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.
