航磁异常与地磁异常特征浅析
|
摘要
祁漫塔格地区是青海省重要的铁多金属矿产地,在平面上对1:5万航磁异常和1:5万地磁异常特征进行了分析对比,并例举了典型铁矿床上磁异常的显示特征,阐述了两者之间的共同点和异同点,从而依据磁异常特征达到识别异常性质的目的。
Qimantage is the major production origin of iron polymetallic deposit in Qinghai Province. In this study, we comparative analyzed the anomalies characteristics of aeromagnetism and geomagnetism on measuring scale of 1:50,000 at a grade intersection. The magnetic anomaly features of some representative iron deposits were illustrated at the same time.The similarities and differences of both were recognized, then the nature of magnetic anomaly was recoginzed based on the anomaly characteristics.
