| 中文摘要: |
| 河南崤山东部浅覆盖区内出现面积达109 km2的低磁异常区,与该区安山岩地层的磁性特征不吻合。区内中河、老里湾两矿区已估算Ag金属量约5500 t,Pb+Zn金属量约130万t。利用1∶5万高精度磁测资料,结合区域地质背景分析了该区高磁异常特征,运用地球物理(低磁异常)块体开展找矿预测,运用齐波夫律推算,低磁异常区块体内预测Ag金属量约18600 t,Pb+Zn金属量约480万t,表明低磁异常区找矿潜力巨大,为该区今后找矿提供了靶区。 |
| 英文摘要: |
| A low magnetic anomaly zone is located in Xiaoshan shallow cover area of 109 km2, not coincide with the magnetic characteristics of andesite strata in this area. It has been estimated that Ag metal content is about 5500t and Pb+Zn metal content is about 1.3 million t in Laoliwan, Zhonghe. According to 1:5 million high magnetic anomaly characteristics, the use of geophysical (low magnetic anomaly) block to carry out prospecting prediction. According to Zipov's law, Ag metal content and Pb+Zn metal content are estimated to be about 18600t and 4.8 million t respectively in the low magnetic anomaly block, which indicating that the low magnetic anomaly area for mine has huge potential and provide the target area for the prospecting. |
