Chemical trends, characterized by the general decrease on Si and Al contents, and the simultaneous increase on Fe+Mg content and Fe/(Fe+Mg) ratio. This can be interpreted in terms of boths, increasing temperatures, and differences in initial bulk chemistry. It is concluded that: (a) Most of the phyllosilicate reactions during the alpine event took place in a close system, with scarce exchanges between coarse- and fine-grained beds, (b) The general trends lead to a transition from di,trioctahedral species toward trioctahedral ones, as a function of increasing depthsspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Alpine metamorphismBetic CordillerasCompositional trendPhyllosilicatesVery low-grade metamorphismjournal articleopen access
