NEW MATERIALS OF STRATIGRAPHIC CLASSIFICATION AND CORRELATION OF THE CARBONIFEROUS IN AWULALE AREA,WESTERN TIANSHAN

The confirming and blocking of Carboniferous stratigraphic units is disputed for more. The 1:50000 Regional Geologic and Mineral surveying discovers a suit of shallow marine carbonate rock—clastic rock building,it abundanted early Carboniferous wrists(Gangamophyllum vetiforme、corals(Gigantopra ductus)et al. fossils in the clastic rock which the age is early Carboniferous later DaTang late-DeWu time. The two suit volcanic rock which intervaled by the Akehsake Formation,which distributing are comparatively tranquilization,the characteristic of rock association are evidence,easily identified and distinguished,easily contrasted in the lage area,which just belong to early Carboniferous and late Carboniferous. The contact connection of three formations are angular unconformity,so the Carboniferous more disintegration three Formations rock-stratigraphic unit,thire are Dahalajunshan Formation、Akeshake Formation and Yishijilike Formation form old to new.
