| Popis: | International audience; The Owen Fracture Zone (OFZ) is the present-day, 800-km-long dextral India Arabia plate boundary, with conspicuous pull-apart basins at stepover areas and at its terminations. We summarize geological evidence documenting the age of formation of the OFZ, based on detailed analysis of geophysical and drilling data in the vicinity of the main pull-apart basins. Although India-Arabia motion started in the Late Cretaceous, we show that the present-day OFZ is a young structure formed at 2.4 Ma. This last structural reorganization of the India-Arabia plate boundary is unrelated to any well-documented kinematic change, leaving questions over its driver. |
