Abstract

The variation in the chemical compositions of biotites, cordierites, garnets and Fe-Ti oxides in peraluminous granites of the Spanish Central System are shown to be functions of the degree of fractionation or evolution of the magma, irrespective of its peraluminosity. The high increase in Mn content in all these phases in the silica-rich granites (SiO (sub 2) approximately 74 %) can be interpreted as a consequence of the incompatible behaviour of this element in highly evolved granites that are sufficiently poor in Ti, Mg and Fe to prevent or diminish crystallization of ore minerals, such as ilmenite.
