Abstract

It is disputed whether Terrae Rossae form mainly out of the bedrock residue, from allochthonous material like aerosols, or by isovolumetric replacement. Furthermore, whether they are mainly relic soils or are still forming is subject to debate. These questions were addressed by comparing the geochemistry of several limestone and basalt based Red Mediterranean Soils with Lithosols on sandstone and limestone in Jordan. It is highlighted that basalt and sandstone bedrocks, and local dust sources contribute to soil development. The Red Mediterranean Soils on limestone are mainly derived from Saharan dust. Growing aridity during the Holocene has apparently increased the share of silt while clay deposition and soil development has been reduced. In conclusion, formation of red soils during the Holocene seems very limited, and the Red Mediterranean Soils may represent remains of a paleolandscape
