Genesis and climatic interpretation of paleosols and calcretes in a plio-pleistocene alluvial fan of the costa blanca (SE Spain)

Occurrence and origin of soils with andic properties in Calabria (southern Italy)

“…Indeed, the abrupt decrease of andic properties in the case of DEL is associated with 1) a significant reduction of the Fe o /Fe d ratio, attaining values similar to those found for paleosols (Costantini et al, 2006;Magliulo et al, 2006;Wagner et al, 2012), and this indicates an older, more weathered, soil environment and ii) a stronger anisotropy of soil matrix due to an iso-orientation of clay minerals which is unusual in the studied Calabrian Andosols. In TAU, the very frequent occurrence of pedorelicts is consistent with soils which develop from "reworked" alluvial fan deposits in the bedrock.…”

Reconstructing Early Pleistocene (1.3Ma) terrestrial environmental change in western Anatolia: Did it drive fluvial terrace formation?

“…One group of authors consider them to originate from a former rooting zone (Wright et al, 1988(Wright et al, , 1995Candy et al, 2003Candy et al, , 2004Eren et al, 2008) while other workers report them to be formed as surface crusts partly due to cyano-bacteria (Rabenhorst et al, 1991;Verrecchia et al, 1995;Wagner et al, 2012). The interpretation of laminar calcretes as former rooting zones considers them to be pedogenic calcretes (Wright and Tucker, 1991), secondary carbonates that form in soil profiles within semi-arid/sub-humid but seasonally dry climates (Goudie, …”

“…The unique situation in Kula is that the local deposits are in turn capped by dated lava flows. Recently, similar Mediterranean palaeosol and calcrete records have been used as multi-proxy evidence of Pleistocene environmental conditions (Candy et al, 2012;Mclaren et al, 2012;Wagner et al, 2012;Küçükuysal et al, 2013;Alçiçek and Alçiçek, 2014). These studies indicate that the most distinctive and effective way to understand the genesis of such pedogenic features is with micro-morphology and stable isotopic composition of carbonates.…”

Climate as a Stratigraphic Tool for Basin Margin Deposition in Intracontinental Basins

“…Pedogenesis often occurs on the surface of stabilised alluvial fan lobes or on the floodplain during periods of reduced fluvial avulsion (Wagner et al, 2012). The formation of palaeosols requires some humidity, therefore they commonly initiate during maximum humidity or the wetting upwards stages of the ACC.…”
