[ES] Se han estudiado las cloritas de materiales pertenecientes a Depresiones postorogénicas de las Cordilleras Béticas, habiéndose medido dos parámetros: grado de sustitución tetraédrica Si por A1 (a partir del espaciado basal) y contenido y distribución de átomos pesados en las capas octaédricas (a partir de relaciones de intensidades basales). No se observan tendencias de variaciones significativas en el A1IV, presentando un valor medio muy constante. En la Depresión de Granada el contenido en hierro está en relación al grado de alteración físico-química sufrida por el material estudiado. Así disminuye con la distancia al área fuente de las series estudiadas. Igualmente, es menor para cloritas de la matriz y paleosuelos que para las de cantos de rocas. En los suelos está claramente en relación al grado de evolución sufrido. En la Depresión de Guadix-Baza, el contenido en hierro se relaciona claramente con el tipo de litología y, por tanto, con el medio de depósito. Así, para series fundamentalmente detríticas es menor que para las de tipo químico depositadas en un medio de alta concentración iónica con escasa o nula removilización de soluciones.
[EN] Chlorites from postorogenic basins of Betic Cordilleres are studied through the behaviour of two parameters measured by X-Ray diffractometry: Tetrahedral A1 after measures of the basal spacing and heavy atoms content and distribution (by basal reflexion intensities relations). It is not observed significant variation trends in the A1IV, being the average tenure constant and near to 1,26. In the Granada basin the Fe content is related to the degree of weathering of the studied material. It decreases when the distance to the source area of the materials increases. In the same way it is lesser for chlorites of cement and soils than for those of the pebbles. For the pedogenic chlorites, a evident relation to the evolution degree of the soils has been shown. In the Guadix-Baza basin the Fe content is clearly related to the lithology and therefore to the sedimentation environment. In the fundamentally detrital series is lower than in those what have been deposited in a chemical environment with high ionic concentration and scanty or null replacement of solutions.
