内蒙古阿拉善左旗克布勒铁铜矿地质特征及找矿标志

摘要

阿拉善左旗克布勒铁铜矿位于石炭纪石英闪长岩与渣尔泰山群曾隆昌组二段的外接触带,矿体总体产状与接触带产状一致,赋存在接触带上的夕卡岩体外侧及其附近围岩中,属于夕卡岩型矿床.石炭纪石英闪长岩为矿体的形成提供了热源和物源,北东向的断裂构造则为石英闪长岩的侵入和成矿热液提供了通道.在分析矿床成矿地质特征的基础上,总结了综合找矿标志.%The Kebule Fe-Cu deposit in Alxa Zuoqi,Inner Mongolia,occurs in the external contact zone of the Carboniferous quartz diorite and the second member of Zenglongchang Formation,Zhartaishan Group.The deposit belongs to skarn type,with orebodies hosted in the skarn and surrounding rocks outside the contact zone.The occurrence of the orebodies is consistent with that of the contact zone.The Carboniferous quartz diorite provides the formation of the orebody with heat and materials.In addition,the northeast-trending fractures serve as the pathway for the quartz diorite intrusion and ore-forming fluid.Based on the analysis of the metallogenic geological characteristics,the authors summarize the comprehensive prospecting indicators.
