Evaporation of seawater: calculated mineral sequences
Abstract:
Van't Hoff's predictions of the mineral sequences to be expected on the evaporation of seawater are based on an oversimplified system. New computer calculation that include calcium-bearing phases are in better agreement with natural occurrences, removing discrepancies that have plagued evaporite geologists for nearly a century. A new hydrologic model that combines equilibrium batch evaporation with fractionation between successive batches is proposed to account for the mineral sequences observed in such classic deposits as the German Zechstein.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or more types of...
