| 摘 要： | 辽西地区中生代陆相盆地及盆岭构造发育，可划分为早中印支期（T1，2）、晚印支期-早燕山期（T3-J1）、中燕山期（J2-J3）、晚燕山期（K1）、末燕山期（K2）5个盆地形成时期.一般地，盆地早期多为断陷阶段，晚期为拗陷阶段.盆地长轴方向为北东向或北北东向，受控于该时期的构造格架.山岭（古隆起）及其间宽广低拗的盆地组合形成盆岭构造.盆岭构造为辽西地区中生代构造的一大特色，可分为侏罗纪和白垩纪2个类型的盆岭构造，也反映了中生代地壳多次的裂陷和伸展作用.

| Abstract: | The Mesozoic continental basins and basin-range structures are well developed in Western Liaoning Province. The basins were formed in five stages, i.e. Early-Middle Indosinian (T1,2), Late Indosinian-Early Yanshanian(T3-J1), Middle Yanshanian ( J2-J3), Late Yanshanian ( K1) and the end of Yanshanian (K2). Generally, the basins express fault-depression in the early stages, while depression in late stages. The major axes of the basins trend NE or NNE, controlled by the tectonic frameworks then. The mountains ... |
