Natural Salt Sequences and Physico-chemical Models,ill 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. ., 1957), will not be discussed here.

Geological Conclusions and Problems,of potassium and magnesium is scarcely ever attained and there is always a predominance of sodium and other carbonates or sulphates. The occurrence of borates and nitrates, on the evidence of the prevailing anions, is a clear indication of non-marine origin. The extent and salt content of terrestrial salt lakes is small (for details, see ., 1938).

The Stability Conditions of Salt Minerals,dering only the main components, and these in controlled concentrations which could be examined systematically, changing values of temperature, pressure and time. . fundamental observations are still valid, and since his time, apart from minor numerical corrections, there have been few basic advances.

Physico-chemical Models,parison of different models with natural salt series is the only direct way of approaching the actual composition of the solutions and the conditions under which they existed, as well as the processes of secondary alteration.

Other Components of Salt Deposits,nents must be considered here, within the limitations indicated above, because they give further information about conditions of formation. However, a review of the geochemistry of salt deposits is not contemplated here (cf. the review by ., 1958).

Introduction,m Table 1 (from . et al., 1949) if water itself is excluded there are actually only six main components in seawater, namely.the cations Na., Mg., Ca., K.,.and.the anions Cl., SO....These are also the components of the salt minerals which form the major part of salt deposits derived from oceanic wate
