Abstract (in english)
   The low-grade phyllosilicates, such as chlorite, metamorphic vermiculite (or Na-biotite), randomly ordered chlorite/vermiculite mixed-layer, and 1 : 1 regular chlorite/vermiculite mixed layer occur as pseudomorphs after pyroxene and as matrix phases in most mafic dykes from the Maláguide Complex (southern Spain). Vermiculite has been recently considered as an alteration product either by weathering (in soils) or by hydrothermal action, but metamorphic vermiculite originated during a prograde metamorphic episode (from chlorite to 8594; biotite) is comparatively rare.
