摘要
龙头坑铁矿床大地构造位置处于钦杭成矿带南部,通过浅部地表工程和深部钻探工程,查明主矿体1层.矿体呈层状、似层状产出,矿体与围岩产状基本一致,层控作用明显.矿体赋存于南华系杨家桥群下坊组硅铁岩段,其形态受地层和构造双重因素的影响.综合考虑区域地质背景、矿床地质特征以及矿石矿物特征,判断该矿床属于沉积变质型.
Abstract
The Longtoukeng iron deposit is located in the southern part of the Qinhang metallogenic belt,and through shallow surface engineering and deep drilling engineering,the main ore body layer 1 has been identified.The ore body is produced in a layered or quasi layered manner,and the attitude of the ore body and surrounding rock is basically consistent,with obvious lay-er control effect.The ore body is located in the Xiafang Formation of the Yangjiaqiao Group in the South China system,and its morphology is influenced by both geological and structural factors.Taking into account the regional geological background,geo-logical characteristics of the deposit,and mineral characteristics of the ore,it is determined that the deposit belongs to the sedi-mentary metamorphic type.
