Natural Salt Sequences and Physico-chemical Models
The calculation of the different models was carried out with due regard to natural occurrences. It is not to be expected, however, that these models will be closely approximated in Nature. Nevertheless, despite their manifold differences, natural salt deposits can be reduced to a few types. The classification given here is based upon purely petrographic and quantative chemical data. Other classifications, based upon geological criteria (cf. Lotze, 1957), will not be discussed here.

- 39.The geologically interesting occurrence of Recent anhydrite has been reported from the Trucial Coast, Persian Gulf. This anhydrite is an early diagenetic mineral, developed in supratidal areas of marine lagoonal carbonate sediments, by displacement (Kinsman, 1966 ).Google Scholar

- 40.Weber, 1931 incorporated Lück’s data and added further doubtful indications such as the occurrence of thenardite and in the potash layer the occurrence of carnallite relicts in vanthoffite (p. 70), and of loeweite in sylvite (p. 69). Further, being unaware of the idioblastic sequence (p. 153, 154), he assumed incorrect age relations between the minerals.Google Scholar
