The distal aluvial fan and the palustrine deposits of the Paracuellos de Jarama area display a variety of specific pedogenic and diagenetic features. The processes affecting these sediments were controlled by: the sedimentary environment, the lithology and initia1 texture of the sediments and by the pedogenic-diagenetic environment in which the transformations occurred. Thus, in the distal alluvial areas (PEL profile) the first processes were the formation of thin carbonate laminae and sepiolite, further, these deposits were silicified and later, a spheroidal dolomite is formed on the opaline chert. In lacustnne environments (UPC profile), drying and root activity led to the formation of palustrine carbonates that were silicified, and the i...
