This is because of the increase of overburden pressure, which causes compaction, and the progressive cementation with age. 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). 1. obsidian A. intrusive igneous 2. granite B. chemical sedimentary 3. conglomerate C. extrusive igneous 4. evaporite D. clastic sedimentary 5. coal E. organic sedimentary 6. marble F. metamorphic 3. evaporite 4. sediment 5. stalactite 6. stalagmite.

The mineralogy of evaporite rocks is complex, with almost 100 varieties possible, but less than a dozen species are volumetrically important. A recurrent vertical pattern of six main facies (euxinic to gypsum fanglo‐merates) is interpreted as a bathymetric, regressive cycle controlled by both sedi‐mentological and tectonic‐eustatic factors. The Earth’s magnetic field aligns the grains, yielding a preferred direction of magnetization. A clast is a fragment of geological detritus, chunks and smaller grains of rock broken off other rocks by physical weathering. Based on these data, for the first time, a number of major faults have been recognized. Evaporite is common in desert areas, where evaporation is high, such as the Great Salt Lake in Utah.
