摘　　要：东爪哇盆地是印尼最重要的含油气盆地之一,其新生代的构造演化可以概括为：两期裂谷和两期挤压。始新世裂谷是印度—澳大利亚板块近南北向俯冲形成的弧后裂谷性盆地。渐新世期间,印度—澳大利亚板块俯冲方向发生变化,在东爪哇地区形成了第二期东西向裂谷。15Ma以来,东爪哇南面的Roo Rise洋底高原与巽他大陆发生碰撞,导致盆地内部早期的正断层形成反转构造,是研究区重要的圈闭类型。3.5~2Ma开始,澳大利亚大陆坡与Banda岛弧发生碰撞,并远程影响到东爪哇盆地,引起盆地内的第二期挤压变形。The East Java Basin is one of the most important oil and gas bearing basins in Indonesia.Its Cenozoic tectonic evolution can be summarized as two rifting phases and two compressional events.The Eocene back-arc rifting basin resulted from the northward subduction of the Indo-Australian plate under Sundaland.The subduction changed its direction to NE-SW in the Oligocene,which induced the second phase of E-W extension and rifting.The Roo Rise ocean plateau,south of East Java,collided with Sundaland at about 15 Ma,which resulted in the formation of major type of oil traps and positive inversion structures in the basin.Part of the Australian proximal continental slope collided with the Banda Volcanic Arc at about 3.5-2 Ma and caused the second phase of compressional deformation in the East Java Basin.
