TECTONIC EVOLUTION AND OIL AND GAS OF TARIM BASIN

According to the new results achieved in the past ten years and more, using mobilism and the theory of polycycle by Huang Jiqing (1977, 1984 ), the formation of the basement of the Tarim basin and its characteri stics are summarized. The prototype basins formed since Sinian times a re classified into rift basin, continental marginal basin, cratonic ba sin, foreland basin and others. The Tarim basin is regarded as a huge oil- and gas-bearing basin superposed by prototype basins of different ages. The tectonic characteristics of these basins including tectonic movements, tectonic migrations, faults and trap types are summarized. In addition, structural control over oil and gas and oil-forming feat ures are analysed. Copyright (C) 1996 Published by Elsevier Science Lt d
