The Badenia salinity crisis, known also as the Wielician crisis, was a crucial event in the middle Miocene history of the Central Paratethys. At that time the seas occupying the aSabkha. Sabkhas are hydrological settings where resurging groundwater form displactive and replacive evaporite minerals in the capillary fringe above a saline water table or in the brine-saturated muds immediately below (Warren, 2010), which are usually distributed in the uppermost interval of tidal flat environment (supratidal zone) in relatively arid climate."High-Energy" and "Low-Energy" Depositional Environments. Flowing water is the dominant natural force causing erosion and deposition on Earth. The faster the water moves, the higher the energy in a physical setting. As flowing water increases in speed, the more it may become turbulent, increasing its ability to lift and move particles.Jul 16, 2013 · Common chemical sediments include the precipitated minerals halite (rock salt), gypsum, calcite, and various forms of ultra-microscopic quartz grains (cryptocrystalline quartz, listed in the table above as "microquartz").
