摘要
根据希兰格拉德铁矿地质特征和物性特征,采用高精度磁测和瞬变电磁测深方法,快速缩小了找矿靶区。通过对物探异常的分析、查证,获得数千万吨铁矿储量及数个找矿有望地段。
According to geological and physical properties of Sierra Grade iron ore deposit, the high precision magnetic survey and transient electromagnetic survey methods are adopted that reduce quickly the ore finding target range. Through confirming and analyzing the abnormalities obtained via geophysical prospecting, several ten--million ton of ore reserve and several zones possibly having ore reserve are detected.
