| 摘 要： | 柴达木盆地北缘是中新生代以来发育的块断带,中新生代盆地受逆冲推覆构造作用形成的构造岩席呈不同的展布形式.本文通过对不同构造部位构造样式的分析、中下侏罗统层间氧化带发育特征的阐述,认为在与盆地蚀源区相向的目的层,即对冲构造样式是古层间氧化带的发育部位,而相一致的单冲构造与斜坡带构造样式是现代层间氧化带发育的有利部位.

| Abstract: | The north margin of Qaidam basin is a fault block which developed from Cenozoic to Mesozoic Era, structrual sheets formed by overthrust and nappe structrue are of different styles in the Cenozoic- Mesozoic basin. After analyzing the structrual styles in different structrual location and the evolution characteristics of interlayer oxidation zones in Middle-Lower Jurassic strata, the authors recognized that paleo interlayer oxidation zone were developed in the dual-upthrust structures where the dip of target layer is againt the eroding plane of the source area and present interlayer oxidation are developed in the mono-upthrust and slope structures where the target layer and the eroding plane of the source area bear the same dip. |
