云南省惠民铁矿床地球物理找矿模型及资源量估算

摘要

通过对惠民铁矿床所在区域、地区、位置三个不同层次的重、磁场特征进行研究,建立了澜沧惠民铁矿床的地球物理找矿模型.结合已验证的钻孔资料及矿石参数,用磁异常拟合体积法求取了76线C1、C2磁异常的资源量,用类比法对矿区其他磁异常进行了资源量估算,与已探明的资源量相比,该矿区尚有一定的找矿潜力.%The geophysical ore-prospecting model of the Huimin iron deposit was established on the basis of studying the characteristics of gravity and magnetic field of the Huimin iron deposit at three different levels. Combined with the proven bore hole data and the parameters of the ores, the authors got the resource quantity of C1 and C2 magnetic anomalies along No. 76 exploration line by using magnetic anomaly to fit the volume of iron ore body. The resource quantity of other magnetic anomalies was also obtained by analogy. A comparison with the proven resource shows that there exists some potential in search for iron ore bodies in this area.
