Mudcracks.

Syneresis cracks are a sedimentary structure developed by the shrinkage of sediment without desiccation – not to be confused with desiccation cracks. Syneresis is the expulsion of a liquid from a gel-like substance. Syneresis cracks are formed by the contraction of clay in response to changes in the salinity of a liquid surrounding a deposit. The cracks can occur, for example, in mudstones ...A (n) ____ is a body of sediment deposited when a river flows into standing water, like a lake or sea.

The back-barrier will include mudcracks, bioturbation, mud-sized sediments, sand from overwash deposits, and cross-stratification dipping towards the coast. The dune field will consist of sand sized particles with bioturbation, wind ripples, trough cross-bedding, and of course, dunes. The seaward beach of the barrier island will contain sand ...The researchers think the mud layer took shape more than 3 billion years ago, after Mars's once bountiful ancient lakes dried up. The cracks then became buried over time by layers of surface sediment, which hardened into stratified rock, before wind erosion once more revealed the fractured patterns we see today.Expert Answer. 100% (1 rating) Q -1 Yes it is True that Mudcracks are useful for 'right-side-up' determination as it indicates which way is Right-side-up.
