This new reinterpretation of the Quaternary evolution of the Pecora River area has several implications, in particular on the nature of the arsenic anomaly known in this area and mainly confined to the fluvial terrigenous deposits. Specifically
, the erosion and dispersal of As-bearing mineralization emplaced between the late Pliocene and the Quaternary in fractures and faults affecting the bedrock of the Arsenti Mount area, was possibly driven by the sedimentary development of the Pecora River
and identifying the potential sources of damaging earthquakes. The AA. pointed out active anticlines based on the correspondence among drainage anomalies, historical seismicity and buried ramps. They also analyzed the evolution of the Plio-Quaternary deformation
in the Mediterranean area, favoured the closing of the sea-ways, connecting the Atlantic with Perimediterranean basins. Consequently the salinity crisis developed, with a relative diachrony. During the Middle Pliocene-Quaternary, the intense thinning of the Tyrrhenian

The main aims of this paper are : to document the late Quaternary palaeoenvironmental evolution of the Vatos polje; to assess the anthropogenic impact on landscape changes; and to set up a geochronological frame for the evolution of the polje. Four
of diagnostic ceramic fragments and, for the first time, IRSL dating techniques were used to establish a local geochronological frame for the polje evolution. The results are discussed against the background of similar studies on late Quaternary polje evolution

In this paper the terminology used in long-term geomorphology is evaluated. Long-term geomorphology is the study of landforms that are mostly pre-Quaternary, Cenozoic, Mesozoic or even Palaeozoic age. Many terms have been introduced to name the long
in the respect that pre-Quaternary landforms were repeatedly covered by Quaternary ice sheets but often survived with different degrees of glacial modification.
