川东隔挡式和黔东北隔槽式褶皱是我国最典型的隔挡、隔槽式构造分布区,对其力学成因,历来有所分岐。笔者以为它们系在一些深,大断裂限制下盖层滑动的产物。从龙门山断裂带至雪峰隆起,如果作一 NW∽SE 向横切剖面(分别从天全—青山岑,华蓥山—雪峰山),便可见一十分有趣的现象,即以川中隆起为中心,其两侧不论在基底起伏、地层展布、褶皱形态、深大断裂的分布以及构造强度面,都有大致成带对称分布的特点,只不过西翼各带宽度很窄、变化迅速而巳。反映了其间具有密切的成因联系。
Chuan east blockage and northeast Guizhou province is the most typical septa-type folds, dividers trough structure distribution, its mechanical causes, has always been divided. I think they are in some deep and large fault rupture cover sliding product. From the Longmenshan fault zone to the Xuefeng uplift, if we make a NW∽SE transverse section (from Tianquan - Qingshansen and Huaying Mountain - Xuefeng Mountain respectively), we can find a very interesting phenomenon, that is, As the center, both sides have the characteristics of roughly symmetrical belt distribution, no matter in the basement undulation, stratigraphic distribution, folds, deep faults and tectonic intensity, except the widths of the west wing are very narrow and change rapidly And already. Reflects the close genetic relationship between them.
