扬子板块北缘中段多期褶皱构造的变形特征及叠加关系
|
摘要
扬子板块北缘在中生代期间经历多期构造变形,早期形成的构造样式多被后期的构造变形改造破坏,仅在大巴山弧形断裂和大洪山弧形带之间的南漳一带较好地保存了早期的构造变形样式。笔者通过对当阳复向斜北段发育的褶皱构造的构造要素测量统计和褶皱叠加关系的解析,在扬子板块北缘中段南漳一带识别出三期走向不同的褶皱叠加构造,按发育早晚顺序分别为NW-SE走向褶皱、NE-SW走向褶皱和近EW走向褶皱,分别对应扬子板块向北俯冲以及后期转入陆内变形、江南–雪峰褶皱逆冲带向NW逆冲推覆和晚侏罗世到早白垩世期间大巴山向SW推进等构造变形过程。
The northern Yangtze Block went through many periods of deformation, within which the early-period structural styles were destroyed and replaced by later ones. Fortunately, records of the early-period deformation styles are reserved in the Nanzhang area, which is tectonically located between the two arc-shaped fault-belts in the northern Yangtze Block: Daba Shan and Dahong Shan. Three phases of folding were recognized in the Dayang synclinorium area, namely the first stage NW-SE trending folds, second stage NE-SW trending folds, and the third stage E-W trending folds. The three phases of folding correspond to the tectonic deformations such as the northward subduction of the Yangtze Block with later intra-continental deformation, the northwest-ward thrusts of the Jiangnan-Xuefeng fold blets and the southwest-ward propagation of Daba Shan fault belts during the late Jurassic to early Cretaceous, respectively.
