山东莱芜地区谷家台铁矿航磁异常特征及找矿前景

Aeromagnetic anomaly characteristics and prospecting potential of Gujiatai Iron Deposit in Laiwu Area,Shandong Province

莱芜地区是我国矽卡岩型铁矿的重要产地,矿山岩体是该地区主要的成矿岩体,区内的谷家台铁矿是该区发现的大型铁矿床。近年来,鲁西潘店地区和张家洼地区找矿取得重大进展,表明山东省内寻找富铁矿仍具有很大潜力。谷家台铁矿自80年代以后未对其外围系统开展深部找矿工作。对谷家台铁矿地质成矿条件及磁异常特征综合分析,结合莱芜接触交代型铁找矿标志,探讨外围及深部找矿前景。

Laiwu Area is an important producing area of skarn iron deposits in China.The mine rock mass is the main ore-forming rock mass in this area.The Gujiatai Iron Deposit in this area is a large iron deposit found in this area.In recent years,great progress has been made in prospecting in Pandian and Zhangjiawa Areas of Luxi,indicating that there is still great potential for finding rich iron deposits in Shandong Province.Since the 1980 s,the deep prospecting work has not been carried out in the peripheral system of the iron mine.This paper makes a comprehensive analysis of the geological metallogenic conditions and magnetic anomaly characteristics of Gujiatai Iron Mine,and discusses the peripheral and deep prospecting prospects in combination with the prospecting criteria of Laiwu contact metasomatic iron.
