Water-rock interaction stages and evolution of metasomatic zoning in the weathering crust

摘要：

Using physico-chemicai modeling, the sequence of formation of mineral zones in weathering crust can be calculated and interpreted in a new way. Two main stages of rock alteration in zones of hypergenesis are distinguished: relic bearing and transformation. On the first stage mineral composition of zones of weathering crust is defined by the interaction of water and parent rock, while on second stage the composition of the weathering products depends on paragenesis of newly-formed minerals.
