安丘-莱州地区低缓磁异常带铁矿找矿前景分析

Analysis on Ore Prospecting Perspective in Low Aeromagnetic Abnormal Iron Deposit in AnqiuLaizhou Area

摘要:

平度市胜合铁矿处于安丘莱州铁矿成矿带中段，为新发现的低品位铁矿床。矿床分布于低缓航磁异常区，产于古元古代粉子山群小宋组地层中，属沉积变质型成因。该区找矿的突破，是安丘莱州铁成矿带弱航磁异常中找矿的一个典型，对今后安丘莱州地区低缓磁异常的找矿起到一定启示作用。

Abstract:

Shenghe iron deposit locates in middle part of AnqiuLaizhou iron mineralization zone in Pingdu city. It is a new discovery lowgrade iron deposit. The deposit is distributed in low aeromagnetic abnormal area, and formed in Xiaosong formation of Fenzishan group in Palaeoproterozoic Era. It belongs to sedimentary metamorphic type deposit. The breakthrough of ore prospecting in this area is a typical one of ore prospecting in low aeromagnetic abnormal area of AnqiuLaizhou iron mineralization zone. It will provide a revelation in ore prospecting in low aeromagnetic abnormal area of AnqiuLaizhou Area in the future.
