3D Analysis of Fe-Ti Oxides and How They Affect Crystal-Plastic Deformation in Atlantis Bank, Southwest Indian Ridge
… 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 …

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

Geochemistry and petrogenesis of the Tsirub nephelinite-basanite intrusions, Aus, southern Namibia
… in southern Namibia are described for the first time. The petrography is very similar to each other wih texture ranging from porphyritic to microporphyritic where olivine is dominant, and sometimes the only, phenocryst/microphenochryst phase, and less commonly clinopyroxen; the groundmass …

New Experimental Data for a Re-Calibration of the Fe-Ti Oxide Thermo-Oxybarometers
Despite their modest modal abundances, Fe-Ti oxides are important accessory minerals in igneous rocks. They are major carriers of rock magnetism and petrologic indicators of temperature and redox conditions during the magmatic stage (Buddington & Lindsley, 1964). The titanomagnetite-ilmenitess …

Petrologic, geochemical and isotopic evolution of rhyolite lavas from the Okataina, Rotorua and Kapenga Volcanic Centres, Taupo Volcanic Zone, New Zealand
The Okataina Volcanic Centre (OVC) is a highly active modern silicic magmatic system at the northeastern end of the central Taupo Volcanic Zone, North Island, New Zealand. This study presents a set of petrographic, mineralogical, geochemical and isotopic data that focuses on the rhyolite lavas …

Petrogenesis of the Mesoproterozoic anorthosite, syenite and carbonatite suites of NW Namibia and their contribution to the metasomatic formation of the Swartbooisdrif sodalite deposits
… emplaced within the basement of NW Namibia. Magmatic activity started with the intrusion of the anorthositic rocks of the Kunene Intrusive Complex (KIC) at 1,385-1,347 Ma. At its south-eastern margin the KIC was invaded by syenite dykes (1,380-1,340 Ma) and younger carbonatites (1,140-1,120 Ma) …
