  • This study uses relicts of Pleistocene sediments and paleosols scattered throughout the Southern Negev Desert to reconstruct the Early to Middle Pleistocene tectonic deformation. The structural and morphological positions of these relicts
  • is examined in relation to the main structural elements in the area and to the present drainage network. The transition from Early to Late Pleistocene drainage patterns is then reconstructed in light of the tectonic activity along the main fault systems

  • Appennino ; Earth surface processes ; Italy ; Mass movement ; Miocene ; Plate tectonics ; Regional geology ; Subduction
  • The early to middle Miocene erosive plate boundary preserved in the Northern Apennines NW of the Sillaro Line is formed by two distinct units – the Sestola-Vidiciatico Tectonic Unit and the Subligurian Units. These two units occupy, respectively
  • , the SE and the NW portions of the studied area. Upon closer examination, the features that distinguish these mapped units do not reflect differing plate boundary processes, but rather the incorporation or non-incorporation of forearctoe mass-wasting
  • deposits into the active subduction channel. In other respects, these two units document similar subduction channel processes, including the contemporaneous activity of multiple sub-parallel slip surfaces. This mode of subduction channel deformation leads
