Figure 2. (color online) Stratigraphic sequence and analytical data for the Fuentiduena section (40°05’14.76”N, 03°12’18.03”W; 560 m asl), 
showing OSL dating results, sediment units (SU), sampling points, palaeo surfaces (PS), grain-size parameters (soil texture %, coarse silt con- 
ient % sand content %), organic content, carbonate content (total and coarse silt sized fractions), ratio between pedogenic and total iron as a 
weathering index, and results of rock magnetic measurements (magnetic susceptibility, frequency-dependent susceptibility, s-ratio). See key 
for detailed sedimentological features, pedogenic features, and kind of samples taken.

Figure 3. Fuentiduefa section photographs and schematic stratigraphic sketch of cross-section. Insets with red lines in the stratigraphic sketch 
refer to photographs. Shovel (60 cm) for scale in photos. (A) Lower part of the section is comprised of layered loamy soil sediments (SU-3) 
above fluvial gravels of mid- to late Pleistocene age (SU-2). (B) Photograph shows transition from the brownish sediments of SU-3 to loess 
deposits above. PS-1 marks the dark reddish paleosol that was formed in SU-4 and the lighter loess of SU-5. (C) Middle and upper part of the 
section. Above the intense PS-1, palaeo surface PS-3 appears much weaker. A whitish horizon with secondary carbonate enrichment is appar- 
ent at the base of SU-7. The strong boundary between SU-8 and SU-9 marks the limit of moisture penetration from the surface. (For interpre- 
tation of references to color in this figure caption, the reader is referred to the web version of this article.)
