چکیده انگلیسی
The study zone is geologically very complex and corresponds to the western limits of the Betic Cordilleras (SW Spain); materials from the Triassic to Holocene are found here. This study demonstrates that most of the surface textures seen on quartz are present on the seven selected heavy minerals. SEM analysis of heavy-mineral grains reveals that certain morphologies are, in part, associated with particular surface textures. This textural analysis enables the source areas to be differentiated more clearly. Equally, it contributes to a deeper knowledge of the various stages of the grains provenance. A good example is the study of the heavy minerals of the Guadalete River terraces.
