is evaporite clastic

The conventional Usiglio model of salt fractionation does not apply to this evaporitic sequence for the following reasons: carbonate which underlies gypsum is not evaporitic but algal in origin; most gypsum did not precipitate from surface brines but at and below a sediment‐water interface occupied by algal mats; a significant portion (10–80%) of gypsum beds is composed of redeposited selenite which was removed from the margins and transported toward the centre of the basin by slope‐controlled currents and gravity flows (debris flows). "Terrigenous Clastic and Evaporite Sedimentation in A Recent Continental-Sabkha Playa Basin, Bristol Dry Lake, California", Depositional and Diagenetic Spectra of Evaporites - A Core Workshop, C. Robertson Handford, Robert G. Loucks, Graham R. Davies Evaporite is common in desert areas, where evaporation is high, such as the Great Salt Lake in Utah. In places such as this, the high temperatures cause evaporation at the edges of lakes and shallow seas. Several different clastic-evaporite units have been identified on the basis of field observations, mineralogy and geochemistry as well as landsat TM data. Based on these data, for the first time, a number of major faults have been recognized. Course. This is because of the increase of overburden pressure, which causes compaction, and the progressive cementation with age.

The recognition of large clastic sulfate deposits in the Mioce ne Messinian onshore of the Mediterranean Basin appears to be in contrast with the hypothesis of a complete desiccation as a consequence of the salinity crisis.

The inferred environmental setting is a residual turbidite trough (Marnoso‐arenacea) evolving abruptly toward lagoonal conditions and filled up to sea level by evaporitic and mechanical (mostly fluvial) processes. Minerals in evaporite rocks include carbonates (especially calcite, dolomite, magnesite, and aragonite), sulfates (anhydrite and gypsum), and chlorides (particularly halite, sylvite, and carnallite), as well as various borates, silicates, nitrates, and sulfocarbonates. 9 times.
