摘要
对尼勒克县松湖铁矿进行的地面磁法测量工作,获取了直接的磁异常数据。通过化极处理和不同高度的延拓分析,圈定了4个磁异常体,并通过用二度半重、磁异常人机联作实时二维剖面反演,拟合出矿体的形态特征,分析了其对应异常体的相对深度,为矿床勘探提供了较为明确的地球物理依据。
The magnetic anomalies were delineated and the direct magnetic data were obtained by the ground magnetic survey in the Songhu iron deposit. On the basis of an analysis of reduction-to-pole of magnetic data and upward continuation, four high magnetic a- nomaly areas were delineated. Through the utilization of the 2.5° gravity and magnetic anomalies for iron deposit characteristics by fitting a curve of 2-dimensional interactive inversion, the relative depth of the high anomaly area was analyzed. The result has provided geophysical foundation for mineral prospecting.
