Lower crustal variability and the crust/mantle transition at the Atlantis Massif oceanic core complex

Structure of oceanic core complexes: Constraints from seafloor gravity measurements made at the Atlantis Massif

[1] Using the DSV Alvin, the relative seafloor gravimeter ROVDOG was deployed at 18 sites on the Atlantis Massif (located at the ridge-transform intersection of the MidAtlantic Ridge and the Atlantis Transform Fault near 30 N, 42 W). These data along with previously collected shipboard gravity and bathymetry provide constraints on the density structure of this oceanic core complex. A series of ...

Iodp Expedition 305: Ocean Core Complex Formation, Atlantis Massif Site U1309 Summary

SCIENCE SUMMARY Site U1309 (Prospectus Site AMFW-01A) is located on the central dome of Atlantis Massif, 15 km west of the median valley axis of the Mid-Atlantic Ridge, where the seafloor coincides with a corrugated detachment fault surface. Site U1309 comprises eight holes drilled within 2 km of one another and along a spreading-parallel corridor (see Expedition 304 Site U1309 Site Summary). H...
