T63. Stratigraphic and morphological markers of extreme events during the Quaternary

-

Congressi SGI-SIMP

The Quaternary is marked by deep variations in geological dynamics at different temporal and areal scales. Endogenic processes (tectonics and geodynamics) and exogenic ones (e.g.: climate variations, sea level changes, glacier dynamics and, lastly, human activity), often together, activated dynamics that have dramatically modified the landscape in a short time span, sometime instantaneously.
Both continental and marine environments, as well as transitional ones, have undergone changes due to the impact of tectonic and volcanic events, climate variations and the related changes in glacier extent, sea level and precipitation distribution. These changes led to dramatic variations in the relief energy. Some environments, in particular continental sedimentary basins (e.g.: alluvial plains and lake areas) and marine and transitional ones (e.g.: ocean floors, continental shelf and lagoon areas), recorded accumulation of sediments, which testify the occurrence of extreme events. On the other hand, coastal areas and river catchments, periglacial and glacial areas could have been strongly shaped by their occurrence, exacerbated by the increase in the relief energy.
The focus of this session is:
  • Highlighting stratigraphic and morphological markers of the impact of extreme events at different time scales during the Quaternary.
  • Propose a correlation at local, regional and where possible global scale of their evidence.
