Geological characteristics of m739 mine and analysis of prospecting prospect

矿床受海西期北西向大断裂构造控制,矿体赋存于大理岩或花岗岩与闪长岩接触带附近,接触处见蛇纹石、磁铁矿、阳起石—透闪石化。矿区内共圈定17个矿体,主矿体为Fe6、Fe1、Fe2、Fe3,矿体在剖面上呈反“S”型构造形迹控制,反“S”型构造具较好找矿前景。

The deposit is controlled by the Hercynian NW trending fault structure.The ore body is located near the contact zone between marble or granite and diorite.Serpentine,magnetite and actinolite tremolite are found at the contact zone.There are 17 ore bodies in the mining area.The main ore bodies are fe6,Fe1,Fe2 and Fe3.The ore bodies are controlled by the anti-s structure trace on the section.The anti-s structure has a good prospect Jing.
