In the Phanerozoic, there are three major geological boundaries : Precambrian / Cambrian, Permian / Triassic and Cretaceous / Tertiary. 显生宇中最重要的三个地层界线是前寒武系寒武系界线、二叠系三叠系界线和白垩系第三系界线。
Three known petroleum systems were identified in the south margin of Junggar basin after our research, which are Permian petroleum system, Jurassic petroleum system and Tertiary petroleum system. 研究认为准噶尔盆地南缘存在三个已知的含油气系统,即二叠系含油气系统、侏罗系含油气系统和第三系含油气系统。
Sedimentary sequences there include the Carboniferous, the Permian, the Jurassic, the Cretaceous and the Tertiary. 发育地层为石炭一二叠系、保罗系、白垩系和第三系。
Vertically, overpressure mainly appears in Permian, Triassic and Jurassic stratum with Carboniferous and Tertiary stratum existing some measured value. 在层位上,超压出现的主要地层层位为二叠系、三叠系和侏罗系,石炭系和第三系也有部分超压实测值。
