摘要(Abstract)：

基于不同构造单元地质记录的分析,结合板块重建及地球动力学背景,对缅甸含油气盆地群的形成演化及其地球动力学背景进行了探讨。研究表明:缅甸含油气盆地群的基底是晚基梅里期变质杂岩;晚白垩世至始新世,新特提斯洋壳向西缅地块之下NNE向斜向俯冲,在西缅地块西缘发育增生楔,而在西缅地块内形成了火山弧、弧前裂陷盆地和弧后裂陷盆地;渐新世以来,新特提斯关闭,随后印度地块与西缅地块北段陆陆碰撞,西缅地块北部的盆地演化为弧后前陆盆地;印度洋壳向西缅地块中段和南段之下NEE向俯冲,西缅地块西缘先期增生楔逐步隆升为印缅山脉,印缅山脉东侧的西缅地块中南部盆地均演化为弧后挤压盆地,印缅山脉西侧的若开盆地成为弧前盆地。

关键词(KeyWords)： 缅甸盆地群;弧前盆地;弧后盆地;盆地演化;新特提斯
