东天山大天生圈沟铁异常特征及其成因探讨

Discussion on iron abnormal characteristics in Datianshengguan Ditch of east Tianshan and its causes

基性岩体中的磁铁矿辉长岩,由于矿体规模大、易开采、易选,国内已有多年的开采历史,东天山大天生圈—牛毛泉一带中基性岩体中局部铁异常明显,本文分析了成矿背景,总结了基性岩体中磁铁矿辉长岩、磁铁矿闪长岩的磁性异常特征,矿体、矿石类型特征,探讨了杂岩体、矿体的成因,对探索同类矿(化)体的勘探具有一定的意义。

For the large orebody, easy to exploit and easy to select, magnetite gabbro in basic rock is mined for many years in China. There is local iron abnormal of basic rock in the area from Datiansheng circle of east Datianshengguan Ditch to Niumao Spring. The pa- per analyzed the metallogenic background, summarized the magnetic anomaly characteristics and orebody type characteristics of the magnetite gabbro and magnetite diorite in basic rock and discussed the causes of complex rock body and orebody. The resuh has certain positive significance for the exploration of the similar orebody.
