| Abstract: |
| The intrabasinal Upper and Lower Sinian sedimentary systems in Tarim Basin are figured out according to the available data of drilled wells and seismic interpretation as well as outcrops of the basin. Awat-Manjar uplift separates Sinian deposits into the east and west deposcenters in the eastern and western parts of the basin. The thickest deposits are at the Kuruktag foreland zone in the northeastern part of the basin, in which Lower Sinian is up to 3400m and Upper Sinian is over 2000m thick. The thinnest deposits are at Awat-Manjar uplift in the middle part of the basin. The development of the east and west Tarim subsiding depressions during Early Simian consti-tuted four areas of sedimentary systems: the East Tarim marine glacier-neritic system, the West Tarim littoral system, the Awat-Manjar coast system and the Southwest Tarim neritic-subabyssal system. |
