摘要
土门金铁矿床位于秦岭造山带北秦岭构造亚带东段的秦岭群之中。本文通过分析该矿床的成矿地质背景、矿体特征及围岩蚀变等,发现区内铁矿床的成因为火山-沉积变质型铁矿,金矿则为热液型,并指出了区内的找矿标志,为进一步开展地质勘查工作提供依据。
Tumen Au-Fe Deposit is located in the east section of North Qinling tectotope of Qinling orogenic belt,which is among Qinling group.The genesis of Fe deposit in the area is volcanic meta-sedimentary type ore deposit and the gold deposit is hydrothermal type.Besides,the prospecting indicator in the area has been pointed out,after the analysis of metallogenic geological setting,ore bodies’ characteristics and wall rock alteration in the area.All mentioned above provide the proof for further geological surveying work.
