摘要
沂水县杨庄南仉林钛、铁矿位于沂沭断裂带汞丹山凸起的东南部,矿体为含磁铁矿钛铁矿角闪石岩,围岩为新太古代晚期第三阶段弱片麻状中粗粒二长花岗岩。矿区圈定钛、铁矿体1个,呈脉状产出,较规则,总长度约1200m,宽25～67m,平均40.3m,延深大于200m。矿体平均品位TFe20.13%,Ti028.86%。属晚期岩浆分异型钛、铁矿床。
Nanzhanglin titanomagnetite deposit in Yangzhuang village of Yishui county locates in southeast of Gongdanshan uplift in Yishu fault belt. Its orebodies are titanomagnetite - bearing hornblende rock, while its country rocks are weak gneissic coarse - medium grain granite in the third phase of late period of Neoarchean. One titanomagnetite orebody has been circled in this mine area, which occurred in vein type regularly. The total length of this orebody is about 1200m, the width is 25 - 67m, the average width is 40.3m, and its extension depth is over 200m. Among the average grade of orebody, the TFe is 20.13% and TiO2 is 8.86%. It belongs to late period of magmatic differentiation type titanomaguetite deposit.
