英文摘要	The Aiketik Group, distributed at the western end of the South Tianshan Mountains, China, is an important lithostratigraphic unit involved in the South Tianshan orogen. It is separated from the adjacent rocks by faults. Generally, the geologists ascribed it to the Upper Carboniferous according to Pseudostaffella sp., Profusulinella sp. and Fusulinella sp. found from the limestone and sandy limestone of Aiketik. Our radiolarian fossils were obtained from the chert samples collected from the Haladaok section located at the upper Tuoshihan River. The fossils mainly include Albaillella undulata Deflandre, Albaillella paradoxa Deflandre, Albaillella sp. aff. A. paradoxa Deflandre, Albaillella sp. cf. A. deflandrei Gourmelon, Albaillella sp., Albaillella excelsa Ishiga, Kito and Imoto (?), Belowea variabilis (Ormiston et Lane), Callella cf. C. parvispinosa Won, Entactinia cf. E. tortispina Ormiston et Lane, Entactinia aff. E. tortispina Ormiston et Lane, Entactinia variospina Won, Entactinia sp., Eostylodictya rota (Won), Latentifistula impella (Ormistone et Lane) (?), Latentifistula turgida Omiston et Lane, Latentifistulidae gen. et. sp. indet. and Polyentactinia cf. aranea Gourmelon. Among them, Albaillella excelsa Ishiga, Kito and Imoto (?) is a Late Permian species with some elements uncertain as there is only one poorly-preserved fossil of this species found so far. And two radiolarian assemblages can be identified from the other fossils. One is the early Early Carboniferous assemblage represented by Albaillella undulata Deflandre, Albaillella paradoxa and Albaillella sp. cf. A. deflandrei Gourmelon. And the other is the late Early Carboniferous assemblage represented by Eostylodictya rota (Won). This is the first discovery of radiolarian fossils in the Aiketik Group, also the first discovery of Late Permian radiolarian fossils in the South Tianshan Mountains. Meanwhile, this is the current westernmost sampling site of radiolarian fossils in the South Tianshan Mountains.
