The dolerite sills outcropping in the Valacloche-Camarena area (SE Iberian Chain), are the expression of an alkaline magmatism, emplaced in Keuper facies sedimentary rocks. Their pre-Hettangian age is deduced from the development of fluidality structures at the top of the sills together with the very low grade contact metamorphism of the host rocks. A differentiation trend, represented by two rock-types, with variable Ti-augite content, is confirmed by geochemical data (REE). The alkaline composition of this magmatism is close to that of the OIB type. Crust-derived enclaves (metapelites and granitoids) are common in these sills, suggesting that magma ascent took place through a fracture system, related to a distensive tectonic regime, that affected different levels of the crust. This magmatism was one of the expressions of the triassic rifting events that are well represented in the SE border of the Iberian Chain.  Un magmatismo alcalino, emplazado en sedimentos tri&#225;sicos en facies Keuper, est&#225; bien representado en los sills doler&#237;ticos del &#225;rea de Valacloche-Camarena (SE de la Cordillera Ib&#233;rica). La edad pre-Hettangiense ha sido deducida a partir de la presencia de estructuras de fluidalidad y de un metamorfismo de contacto de grado muy d&#233;bil. Petrol&#243;gicamente se identifica una fraccionaci&#243;n seg&#250;n dos litotipos (con contenido variable en Ti-augita) que est&#225; corroborada por los datos de composici&#243;n geoqu&#237;mica (en tierras raras); la composici&#243;n alcalina de este magmatismo es pr&#243;xima a la del tipo OIB. La presencia, frecuente, de enclaves de corteza (metapelitas y granitoides) indica una fracturaci&#243;n que, en condiciones distensivas, afect&#243; a distintos niveles de dicha corteza. Este magmatismo est&#225; ligado al rifting tri&#225;sico que est&#225; bien expresado en el borde SE de la Cordillera Ib&#233;rica
