摘　　要：切列克其铁矿是西昆仑地区典型的海相沉积(改造)型菱铁矿床,是前震旦纪基底经长期风化剥蚀的含铁质碎屑物,迁移至阿克赛钦早古生代(早志留世)陆缘沉积盆地沉淀和成岩,经历二叠纪末至中三叠世末古特提斯洋闭合产生的区域变质作用和侵入的花岗岩热液叠加作用改造形成.Qieliekeqi siderite deposit is a sea-facies sedimentary-type（depositing-reworking）one and a ferrian material which had been winded and eroded from the shelf shell of Pre-Sinian basement uprising for a long time,moved to Akesai shelf-edge sedimentary basin（Early Silurian）of Early Paleozoic to deposit and make diagenesis and experienced regional metamorphism and thermal superposition by granite intruding when Tethys ocean closed from the end of Permian to the middle Tertiery.
