The development of these highs is further supported by the presence of pedogenetic
profiles (laterites: Marini, 1984) in areas where the Genna Selole Fm is almost absent, while the first Middle Jurassic deposits are impure carbonates of the Ussassai-Perdasdefogu lithofacies; these are interpreted as the areas where the continental conditions persisted for a longer timespan.
2001 Chronology of Holocene pedogenetic
events in the Pampean area of Argentina.
With the progress in the pine coalescence at the end of the second decade, the ground vegetation tends to disappear from the sown stands, and its importance decreases with pedogenetic
Although the horizon is only 2-3 cm thick, it is clearly pedogenetic
and can be qualified as cambic.
Elevated portion of clay fraction in the Bt and Bth horizons indicates the process of pedogenetic
on steep slopes, the pedogenetic
process remains incomplete and lithosoils (lithic Xerorthents) are formed.
It means that terrestrial processes during different stages of the Baltic Sea have great geological, pedogenetic
, and archaeological importance.
Degree of weathering and pedogenetic
implications Since both sites have closely similar climate and natural vegetation, the chemical characteristic of the parent material and relief appear to be the dominant factors that influenced the characteristics and formation of the two soils.
G and H), where the basal part, which rests paraconformably on the Verrucano Lombardo continental red beds locally through a surface bearing dolomitic nodules of probably pedogenetic
origin, may be interpreted as deposited in fluvial and coastal environments, bordered by mud-dominated areas.
Striping appears to be sedimentary in origin, but earlier pedogenetic
phenomena cannot be excluded either, as it has been described from France (Fichter et al.
At the 'big picture' level, there are two important published frameworks that have provided, for more than fifty years, the 'soil 101' conceptual frameworks for soil diversity and soil dynamics: the 'Clorpt' equation of Jenny (1941) and the pedogenetic
theory of Simonson (1959).
Soil horizons have been indicated a soil with a pedogenetic
