摘要
印支期以来,中国大陆在三面受挤的缩合构造环境下,经历了4期构造变格作用(T3—J2,J3—K1,K2—E,E3/N—Q),秦岭—大别两侧发育了相应的陆相盆地原型,并形成了复杂的原型并列叠加关系。在第一构造变格期,以发育压性陆内前陆盆地原型为主;在第二构造变格期,以发育压性陆内前陆盆地和走滑盆地原型为主;在第三构造变格期,以发育伸展断陷盆地原型为主;在第四构造变格期,以发育坳陷盆地原型为主。
Since the Indosinian epoch, under a condensing tectonic environment compressed from 3 sides, the Chinese continent has experienced 4 stages of tectonic evolution： T3-J2, J3-K1, K2-E, and E3/N-Q, resulting in corresponding basin prototypes along both sides of the Qinling-Dabie orogenic belt. The 1st stage is characterised by compressional intracontinental foreland basin prototype, the 2nd by compressional intracontinental foreland and strike-slip basin prototype, the 3rd by extentional rift-subsidence basin proto-type, and the 4th by down-warped basin prototype.
