%X In the present work, some rocks of igneous facies associated to Keuper materials, are studied. These rocks, previously referred to as ophites, consist in fact of plutonic rocks, compositionally ranging from syenites to monzogabbros. Field, petrographic and geochemical data appear to indicate that these igneous rocks facies were a consequence of metasomatic transformation processes that took place between allocthonous silica-alkaline elements and suitable wall-rocks, constituted, in this case, of evaporitic marls of Keuper facies. Se describen algunos caracteres geol¨®gicos, petrogr¨¢ficos y geoqu¨ªmicos de unas rocas ¨ªgneas, que en peque os afloramientos aparecen asociadas a materiales del Keuper. Estas rocas, que estaban citadas como ofitas, corresponden principalmente a facies granudas entre sienitas y monzogabros. El ambiente de los afloramientos, relaciones de contacto, caracteres petrogr¨¢ficos y qu¨ªmicos, parecen indicar que las rocas ¨ªgneas fueron el resultado de procesos de metasomatismo originados por fluidos s¨ªlico-alcalinos que transformaron los materiales encajantes margoevapor¨ªticos del Keuper.
