猴儿头铁矿成矿模式分析

Analysis of Metallogenic Model of Houertou Iron Deposit

猴儿头铁矿床处于华北板块阿拉善地块祁吕贺兰山字形构造前弧西翼褶皱带的北部。其属于龙首山镍、铜、钴、铂族、铅、锌、铁、锰、磷、铀成矿带,临泽窑泉-东小口子铁锰成矿区。近年来,通过进一步勘查,工作区内共圈定铁锰矿体4条。经综合研究,该矿床是以沉积作用为主导,经后期区域变质和热液改造的复生矿床。

The Houertou iron deposit is located in the north of the fold belt of the west wing of the Qilianshan-Lvliangshan-Helanshan epsilon-type structural front arc in the Alxa block of the North China plate.It belongs to the Longshoushan nickel,copper,cobalt,platinum group,lead,zinc,iron,manganese,phosphorus,uranium metallogenic belt,and the Linze Yaoquan-Dongxiaokouzi iron-manganese metallogenic zone.In recent years,through further exploration,a total of 4 iron-manganese ore bodies have been delineated in the working area.After comprehensive research,the deposit is a regenerated deposit dominated by sedimentation and transformed by regional metamorphism and hydrothermal fluid.
