WebSyneresis cracks (also known as subaqueous shrinkage cracks) are a sedimentary structure developed by the shrinkage of sediment without desiccation – not to be confused with desiccation cracks. [2] Syneresis is the expulsion of a liquid from a gel-like substance. WebTherefore, it can be inferred that the desiccation cracks developed in two stages: the stage of rapid growth and stage of the steady state, in parallel with the increasing number of wetting–drying cycles. In the rapid growth stage, cracks developed quickly after the …
