新疆冰达坂-阿拉沟成矿条件及有利区带

天山构造带是中亚成矿域天山兴蒙成矿省天山大型超大型成矿带的重要地段,而冰达坂-阿拉沟一带是最有利成矿地段之一。在1∶5万区调矿产研究基础上,以该带已知矿(床)点地球化学异常和实际调研新认识,对该区带金属矿产分布规律、地质、地球化学背景等成矿条件进行了较系统研究,对冰达坂-阿拉沟一带以金、铜为主的多金属矿产成矿规律进行了分析总结,划分出冰达坂夏热嘎韧性剪切带构造蚀变岩型Au、Cu成矿带、察汗诺尔阿拉沟构造蚀变岩型Au、Cu、Fe成矿带、萨尔托斯豹子沟黑色岩系Au、Cu 3个成矿带。在此基础上,综合优选出东部地区豹子沟、豹子沟北、豹子沟西、阿拉沟大桥、夏格泽和八一公社6个有利成矿远景区,并指出了今后找矿工作的重点靶区。

Metallogenetic Environment and Prospective Provinces of Bingdaban-Alagou Zone of Enrichment in Tianshan Mountains, Xingjiang

Tianshan tectonic belt is the most important metallogenetic region of Tianshan large to super-large metallogenetic belt in Tianshan-Xingmeng metallogenetic province in the Central Asia metallogenetic domain, and Bingdaban-Alagou zone is the most favorable one in this region. According to the geochemical anomaly in known mineral deposits and mineralized sites and the new geological recognization from 1 ; 50 000 investigation, some metallogenetic factors in Bingdaban-Alagou zone, such as mineral distribution, geological setting, geological structure, geochemical background etc, are analyzed the metallogenetic regularity about multimetal mineral deposits dominated by Au and Cu is summarized, the zone is divided into three metallogenetic belts. Based on the discussion of each metallogenetic belt, six metallogenetic prospective provinces of Au and Cu are optioned synthetically, that is, Baozigou, North Baozigou, West Baozigou, Alagou bridge, Xiageze and Bayi commune, and further exploratory target areas in this zone are proposed.
