Modeling of Magmatic and Allied Processespresentsmethods and models for the quantification of geological processes. Conceptual models for magmatic differentiation involving crystallization and mixing are presented and applied to field and textural data. Model equations for the degree of partial melting in presence perturbations of lithospheric geotherms and partitioning of trace/radioactive elements in thematrix and melts, and the formationof continents with melt additions are described. Diverse magmatic products are shown to result from differentiation processes rather than...
