摘要
德勒诺尔铁矿是近年新发现的大型磁铁矿床,位于祁连山造山带中祁连陆块。铁矿体赋存于蓟县系泥硅质板岩中,矿体呈层状产出,与围岩整合接触,矿石主要为变余结构、条带状构造,矿石矿物为磁铁矿,具有沉积变质特征。该矿床的发现对在中祁连地区寻找同类型矿床具有一定的指导意义,同时也填补了该区铁矿勘查找矿空白。
Delenuoer iron deposit is a large scale magnetite deposit,which is discovered recently in Qilian block of Qianlianshan Orogenic Belt.Within in silicious slate of Jixian System layered iron body conformably contact with wall rock.The ore show exhibit palimpsest texture and banded structure,and ore mineral is magnetite with the feature of sedimentary metamorphism.It is the first time to find out magnetite deposit in the middle Qilian Region,and the discovery of this deposit is of significance to search the sa...
