Comparative of Different Segmentations and Zones During Cretaceous and Paleogene in North Tarim Basin

Key words: 
• Kuche Depression

Abstract: There are many sedimentary facies, which are alluvial fans, terminal fans, fandelta, braideddelta, meanderingdelta, lacustrine facies,lagoon and beach facies，in Cretaceous and Paleogene, Kuche DepressionTabei area, northern Tarim Basin. The lithology assemblages and sedimentary facies are different in north and south zone, also in the east, middle and west segmentation. The north zones are made up of coarse clastics, which are mainly fandelta. The south zones are composed of middle and fine clastics,which are mainly braideddelta. The differences are controlled by palaeostructure, palaeotopographical gradient, palaeoclimate and the distance to provenance.
