Zusammenfassung
The presence as well as types of pedogenic carbonate deposits within miocene formations of the NE Madrid Basin are mainly linked to two majar 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 a/so found in b) deposits. In a broad sense, both mesoscale and textura/ features (Fe-Mn oxides remobilization and carbonate accumulation) of the pedogenic profiles display sorne variety resulting from different sedimentation rates, substrate nature and water hosting, al/ the parameters being controlled by pa/eogeography.
