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

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.
