Issues of stratigraphy of the USSR

Abstract

Geosynclinal and platform sedimentary complexes (formations)Geosynclinal sediments are intensely folded, metamorphosed and ruptured by synorogenic intrusions. They usually have a greater thickness - thousands of meters for a system and even for divisions of the system. Only in geosynclinal sediments are found flysch and molasse complexes, graywacke and aspid shale strata, and thick reef limestones.
