摘要

Unconformably contact between the sandstone-siltstone of the Sangtamu Formation and limestone of the Lianglitag Formation in Ordovician, Kaitian, exists in the Tazhong High, central Tarim Platform.spacerun: yes">  It distinctively indicates a regional tectonic uplift event happened with duration of about 1 Ma.spacerun: yes">  A suite of coalesced, collapsed-paleocave sediment occurred from the 4 125.64 133.space prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />9 m drilling core of the well Zhonggu 31 is assigned to the Member 3 of the Lianglitag Formation.spacerun: yes">  The depth between the cave-ceiling and the top of the Lianglitag Formation is about 190 m.spacerun: yes">  The sediment-fill facies mainly consist of chaotic breccias sourced from the cave-wall, which the latter had been reefal rocks originally.
