Аннотация:Condensed sections (CS) are abnormally thin but nominally complete sections embracing large stratigraphic intervals. They are subdivided with regard to sedimentation rate into CS (at sedimentation rate of 0.5–1 cm/ka) and ultracondensed sections (with a sedimentation rate <0.5 cm/ka), which can be both deep-water and shallow-water types. The mechanisms of CS accumulation include mechanical, chemical, biotic condensation, and nondeposition. Their combinations allow one to suggest some models of CS accumulation: (1) fast and (2) slow sea level rise and/or its low amplitude fluctuations; (3) sea level drop; (4) global warming and (5) global cooling.
