  1. Normalized mechanical properties of resedimented Gulf of Mexico clay from Integrated Ocean Drilling Program Expedition Leg 308

    Mazzei, David P. C. (David Peter Clark)Massachusetts Institute of Technology2008

    During Integrated Ocean Drilling Program (IODP) Expedition Leg 308, many Whole Core Samples were recovered from the Ursa Basin in the Gulf of Mexico. Post-cruise geotechnical testing found these samples to be highly disturbed due to the sampling process. This research will determine mechanical …

  7. The Impact of Fe-Ti Oxide Concentration on the Structural Ridgity of the Lower Oceanic Crust, Atlantis Bank, Southwest Indian Ridge

    Winkler, Daniel2017

    <p>Fe-Ti oxides are important components of oceanic core complexes (OCC) formed at slow-spreading mid-ocean ridges since Fe-Ti oxides are more susceptible to crystal-plastic deformation than silicate minerals. This study investigated the predicted relationship between the presence and concentration …
