世界上几乎所有主要的地向斜-造山带中,都发育有所谓的“复理层”(flyseh)或“复理式互层”(Flysch-type alternation)地层。它最显著的特征是发育有浊流沉积物及其有关的地层,厚度可达数百米,有时数千米。但在地向斜-造山带沉积物中,仅分布于一定层序的范围内,反映地向斜发生分化后,造山运动开始时期,或其进一步发展时,沉积盆地比较急速的沉降。 Almost all major synclinal-orogenic belts in the world develop so-called “flyseh” or “Flysch-type alternation” formations. Its most prominent feature is the development of turbidity flow sediments and related strata, the thickness of up to hundreds of meters, and sometimes kilometers. However, in the synclinal-orogenic belt sediments, they are only distributed within a certain sequence range, reflecting the relatively rapid settlement of sedimentary basins after the syncline syncopation occurred, the beginning of orogenic movement, or its further development.
