摘　　要：西昆仑奇自拉夫组(D q)被公认是一套原特提斯演化最终阶段形成的磨拉石建造,在以往的地质工作中,地质工作者仅仅将其作为西昆仑造山带首轮威尔逊演化旋回结束的标志层,而很少有人将其作为找矿标志层进行矿产勘查工作。近来笔者在西昆仑进行矿产资源远景调查过程中,在阿克苏塔格一带的奇自拉夫组地层中发现了一条宽5 m、长度不详的铜(伴铅锌)矿化带,初步分析铜品位0.45%~0.89%,孔雀石发育。该铜矿化带的发现,为下一步在西昆仑广泛分布的奇自拉夫组地层中探寻该类铜矿床提供了线索和依据。Qizilafu Formation,located in the Western Kunlun,is recognized as a set of molasse formation in the final stage of the evolution of the Proto-Tethys.It used to be regarded only as the marker of the end of the first Wilson cycle in the Western Kunlun orogenic belt,yet rarely as a prospecting marker bed for mineral exploration.In the process of mineral resources prospecting in Western Kunlun,a copper(with lead-zinc)mineralization belt was found in Qizilafu Formation in Akesutage area.Preliminary analysis shows a copper grade of 0.45%-0.89%,with a width of 5 meters,length unknown.The copper mineralization belt,provide information and evidence for the next step to explore copper deposit in Qizilafu Formation which is widely distributed in Western Kunlun.
