This project focuses on the importance of the relationship between Fe-Ti oxide abundance and interconnectivity, and crystal-plastic deformation in Atlantis Bank, Southwest Indian Ridge by utilizing Micro-CT scanning. This was done through comparing the Micro-CT scans of 15 samples from three different Ocean Drilling Program and International Ocean Discovery Program drill holes using the Nikon NIS Advanced Research 3-D visualization program and producing plots and statistics from MATLAB. Results indicate a wide range of textures across a range of crystal-plastic fabric intensity and Fe-Ti oxide abundance. Ultimately, there was a generally positive relationship between depth, CPF intensity, and Fe-Ti oxide percent. The CPF intensity and Fe-Ti oxide abundance was greater at shallower depths in all holes. The Fe-Ti oxide abundance and CPF intensity had a positive correlation through a CPF intensity of 3, but then seemed to have a negative correlation with CPF intensities of 4; a pattern also seen in 2D studies of similar samples. These relationships support a weaker crust, which would be easier for movement to occur, accounting for the deformation and motion of the OCC Atlantis Bank.
