Significado paleogeográfico de las texturas y acumulaciones de carbonatos en perfiles edáficos de la Unidad Intermedia del Mioceno de la Cuenca de Madrid (prov. de Guadalajara)
The presence as well as types of pedogenic carbonate deposits within miocene formations of the NE Madrid Basin are mainly linked to two major differentitated environments: a) proximal alluvial fan environments and b) distal alluvial fan and flood-plain environments. The pedogenic profiles developed...

| Sumario: | The presence as well as types of pedogenic carbonate deposits within miocene formations of the NE Madrid Basin are mainly linked to two major differentitated environments: a) proximal alluvial fan environments and b) distal alluvial fan and flood-plain environments. The pedogenic profiles developed in palustrine areas show sorne features also found in b) deposits. In a broad sense, both mesoscale and textural features (Fe-Mn oxides remobilization and carbonate accumulation) of the pedogenic profiles display some variety resulting from different sedimentation rates, substrate nature and water hosting, all the parameters being controlled by paleogeography |
