Cooling Rates and the Depth of Detachment Faulting At Oceanic Core Complexes: Evidence from Zircon Pb/U and (U-Th)/He Ages
Author(s):Grimes, C. B.; Cheadle, Michael; John, Barbara; Reiners, P. W.; Wooden, J. L.; Grimes, C. B.; Cheadle, Michael; John, Barbara; Reiners, P. W.; Wooden, J. L.
Oceanic detachment faulting represents a distinct mode of seafloor spreading at slow spreading mid-ocean ridges, but many questions persist about the thermal evolution and depth of faulting. We present new Pb/U and (U-Th)/He ...
Strain Localization Along the Atlantis Bank Oceanic Detachment Fault System, Southwest Indian Ridge
Author(s):Miranda, E. A.; John, Barbara; Miranda, E. A.; John, Barbara
Microstructural observations and mineral thermometry from in situ samples collected from the Atlantis Bank oceanic core complex (SW Indian Ridge) indicate that detachment faulting was initiated under hypersolidus conditions ...
