中国南天山西端的艾克提克群是卷入南天山造山带的一个重要的岩石地层单元,其与相邻地层单元均以断层接触.以往根据在其灰岩和砂质灰岩中发现的Pseudostaffella sp.,Profusulinella sp.和Fusulinella sp.将其归属于上石炭统.我们的放射虫化石发现于托什罕河上游的哈拉道克剖面,主要包括Albaillella undulata Deflandre,Al-baillella paradoxa Deflandre, Albaillella sp. aff. A. paradoxa Deflandre, Albaillella sp. cf. A. deflandrei Gourelon,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, En-tactinia variospina Won, Entactinia sp., Eostylodictya rota (Won), Latentifistula impella (Ormistone et Lane) (?), La-tentifistula turgida Omiston et Lane, Latentifistulidae gen. et. sp. indet. 和 Polyentac tinia cf. aranea Gourmelon. 其中,Albaillella excelsa Ishiga,Kito and Imoto(?)的时代为晚二叠世(存疑),其余可以划分出早石炭世早期和晚期两个放射虫化石组合:前者以Albaillella undulata Deflandre,Albaillella paradoxa Deflandre和Albaillella sp.cf. A.deflan-dre Gourmelon为代表,后者以Eostylodictya rota(Won)为代表.这是艾克提克群中首次发现放射虫化石,同时是在中国南天山首次发现晚二叠世放射虫化石,也是中国南天山最西部的放射虫化石点,具有重要的地质研究意义.
中國南天山西耑的艾剋提剋群是捲入南天山造山帶的一箇重要的巖石地層單元,其與相鄰地層單元均以斷層接觸.以往根據在其灰巖和砂質灰巖中髮現的Pseudostaffella sp.,Profusulinella sp.和Fusulinella sp.將其歸屬于上石炭統.我們的放射蟲化石髮現于託什罕河上遊的哈拉道剋剖麵,主要包括Albaillella undulata Deflandre,Al-baillella paradoxa Deflandre, Albaillella sp. aff.

A.deflan-dre Gourmelon為代錶,後者以Eostylodictya rota(Won)為代錶.這是艾剋提剋群中首次髮現放射蟲化石,同時是在中國南天山首次髮現晚二疊世放射蟲化石,也是中國南天山最西部的放射蟲化石點,具有重要的地質研究意義.
