摘要：

寒武纪以来,该区板块构造演化史可分为;被动大陆边缘阶段(Pz1)、被动大陆边缘向大陆一地块间碰撞边缘转变阶段(D1—C1)、碰撞前陆盆地阶段(C2—P1)、陆内沉陷盆地阶段(P2—Q)。它们控制了不同类型沉积盆地的发育和叠合,还控制了盆地的结构、构造、沉积和热演化史,以及区内油气的生成、运移和富集带的展布。

Abstract:

The Junggar Basin is a large superimposed basin bated on a Pre-Cambrian massif. Since the Cambrian, the plate tectonic evolution of the northeastern Junggar Basin can be divided into 4 periods as follows: 1. The passive continental margin phase (Pz1); 2. The transform phase from passive continental margin to continental collision (D1-C1); 3. The collision foreland basin phase (C2-P1); 4. The down warping inland phase (P2-Q). The evolution of plate tectonics controlled the development of the sedimentary basin. Corresponding to the plate tectonic history, the northeastern Junggar Basin consisted of a miogeolinai prism (C-C1), a collision foreland basin(C2-C1),and a down warping basin (P2-Q) ect,. They gave abnudant organicmaterial for the formation of petroleum. The evolution of plate tectonics also controlled the geometric shape, the structure, the sedimentation and the thermal evolution of the basin, and so thus controlled the generation, migration aad accumulation of oil and gas.
