Abstract

The Late Permian (Wuchiapingian) Alcotas Formation in the SE Iberian Ranges
consists of one red alluvial succession where abundant soil profiles developed.
Detailed petrographical and sedimentological studies in seven sections of
the Alcotas Formation allow six different types of palaeosols, with
distinctive characteristics and different palaeogeographical distribution, to be
distinguished throughout the South-eastern Iberian Basin. These characteristics
are, in turn, related to topographic, climatic and tectonic controls. The vertical
distribution of the palaeosols is used to differentiate the formation in three parts
from bottom to top showing both drastic and gradual vertical upwards
palaeoenvironmental changes in the sections. Reconstruction of
palaeoenvironmental conditions based on palaeosols provides evidence for
understanding the events that occurred during the Late Permian, some few
millions of years before the well-known Permian-Triassic global crisis.
