Abstract：The Lower Cretaceous Kizilsu Group in Jianggejieer area,southwestern Tarim Basin,is divided into five lithologic units,which are mainly composed of argillaceous siltstone,lithic sandstone,pebbly sandstone,and conglomerate,and were mainly deposited in braided river delta settings. The Upper Cretaceous Kukbai Formation,overlying the Kezilesu Group,is composed of shell limestone and gypsum mudstone,and was deposited in shallow marine and littoral-lake settings. The Upper Jurassic Kuzigunsu Formation underlying the Kizilsu Group is mainly composed of conglomerate,sandy conglomerate and quartzose sandstone of alluvial fan facies. According to the sedimentary characteristic of the Lower Cretaceous Kizilsu Group in this area,terrigenous clastic deposition was dominated during the Early Cretaceous,whereas marine deposition during the Late Cretaceous. In contrast to the stratigraphic sequence of the pull-apart fault basin(the Sarekbayi Basin) in the north of intracontinental orogenic belt,the stratigraphic sequence of the Lower Cretaceous Kizilsu Formation in the Sarekbayi Basin only contain the lower three units,missing the upper lithologic units,and an uplift occurred in the southwest Tianshan Mountains in the north of the Tarim Basin during the late Early Cretaceous. The Lower Cretaceous Kizilsu Group is the ore-bearing layer of copper,lead,zinc and uranium deposits,and also an important reservoir for oil and natural gas in the Tarim Basin. Asphalt and other organic matter are often found in copper,lead,zinc and other ores. The organic matter was mainly originated from the coal-bearing source rocks of the underlying Jurassic strata,which was involved in the mineralization of metal minerals through ore-forming fluids. Therefore,the phenomenon of multi-mineral “coexisting in the same basin” will be more meaningful to study as a whole metallogenic system in sedimentary basin.
