Abstract

A multi-disciplinary approach was performed to investigate 2 compound geosols included between wind-blown deposits at the top, and interglacial (MIS 5) beach sediments at the bottom, located along the Alghero coast (North-western Sardinia, Italy). A sedimentological and morphological study was carried out on the profile in the field, and samples collected on the main pedomembers were subjected to several laboratory analyses. Dating was performed by means of Optically Stimulated Luminescence (OSL). The studied geosols show the evidence of a complex pedosedimentary evolution. The results indicate that the coastal area of the central Mediterranean kept the relatively warm conditions typical of the interglacial climate for most of the Early Würm and reached cold conditions only at about 70 ka, possibly in relation to the rapid cooling of the Heinrich event H7. The pedogenic features observed in the upper geosol indicate that in the study area the Middle Würm interstadial events were intense enough to influence soil pedogenesis
