青河县加马特一带铜钴金成矿地质条件

Analysis of Cop-Co-Au polymetallic metallogenic geological conditions in Gamat area of Qinghe County

研究区位于萨吾尔一二台Cu-Ni-Au-Mo-Co-Fe成矿带内,区内成矿地质条件良好,华里西逆断层为晚石炭世-早二叠世侵入岩提供了良好的上升通道,侵位于泥盆系、石炭系地层中。其中,科克萨依小型金矿床、喀苏翁金铜钴矿点、阿拉塔斯金矿点、阿拉塔斯南金矿点、阿拉塔斯东金矿点均位于中泥盆北塔山组和统蕴都喀拉组地层中。根据成矿条件和矿床分布特征,将研究区划分为加马特铜钴金成矿区、墩古鲁特金铜成矿区、喀苏翁金铜成矿区,各成矿区成矿类型相似,找矿远景较好。

The study area is located in the Saur-Ertai Cu-Ni-Au-Mo-Co-Fe metallogenic belt with favorable metallogenic geological conditions.The Hualixi thrust fault provides a good uplift channel for the Late Carboniferan-Early Permian intrusive rocks,and it is located in the Devonian and Carboniferous strata.Among them,Keksayi small gold deposit,Kasuweng au-copper-Co deposit,Alatas gold deposit,Alatas South gold deposit and East Alatas gold deposit are all located in the Middle Devonian Beitashan Formation and Yundukla Formation.According to the metallogenic conditions and deposit distribution characteristics,the research areas are divided into Gamat copper-cobalt metallogenic area,Dungulut gold-copper metallogenic area and Kasuweng gold-copper metallogenic area.All the metallogenic types are similar and the prospecting prospects are good.
