  • and with axes striking between EW and NWSE. These folds are not related to thrust tectonics. Two different fault systems oriented NS and EW were evidenced ; the first one is constituted prevalently by normal faults, whereas, the faults of the second system shows

  • Field studies coupled with interpretation of topographic maps resulted in the identification and delineation of a large number of trending active faults which post-date the NW-SE oriented thrust system and shear zones. Recent movement
  • on the northerly-trending faults has caused not only pronounced deflection of rivers and streams but also damage to recently constructed river bridges and subsidence of roads. Movements along faults and thrusts are also responsible for the abrupt rise of mountain

  • Radiolarians of Middle Jurassic age provide the first direct age determination from oceanic sediments associated with the Chenaillet-Montgenèvre ophiolite (Piemonte zone). This datum obtained from radiolarites of the Lago Nero-Replatte thrust sheet
  • pelagic sedimentation, or more likely that the Lago Nero-Replatte and the Chenaillet s.s. thrust sheets are distinct and distant pieces of lithosphere. These results strengthen the Bathonian correlation of widespread seafloor spreading in both western

  • Formation) accumulated in piggy-back basins. In this context the clay mineralogy was used as a tool to study the emplacement of thrust sheets using a detailed powder X-ray diffraction studies of illite-smectite mixed layers clay minerals. - (NF)

  • indicating climatic changes during late Quaternary time. This study suggests that formation of the paleosols in NW Himalayas was mainly controlled by warmer intervals during the last glaciation and the movement along the adjacent thrusts.

  • The Central Apennine foreland basin system in the Marche and Abruzzi regions of Italy preserves the eastern leading edge of the Apennine orogenic wedge, formed from late Miocene to Pleistocene. Four thrust stacks make up this external portion
