| Abstract: | The Devonian strata in the Aggikkol lake region of the East K.unhin Mts.was first put on record by Zhao Ziyun et al-(1982).A series of carbonate rocks about 4000m thick hearing Tabulata fossils Fatosites and Squ-amcofavosites exposed to the south of the Aqqikkol lake was considered to be Middle Devonian series and was named the Bulakebashi Group in their report of the regional geolo-logical survey.In this paper the Bulakebashi Group is divided into three parts; Middle-Upper Devonian (unnamed).Lower Middle Devonian (unnamed) and Kalachuka Formation of Lower Devonian (new name).The Kalachuka formation, 185 m in thickness, is composed of grey-black bioli-thite, siliceous limestone, marlite intercalated with grey shale, sandstone and siltstone and may be fur^ ther subdivided into three members. |
