Poikilitic textures, heteradcumulates and zoned orthopyroxenes in the Ntaka Ultramafic Complex, Tanzania: Implications for crystallization mechanisms of oikocrysts

The late Proterozoic Ntaka Ultramafic Complex is a body of dominantly pyroxenitic cumulate rocks containing cyclic alternations of olivine-orthopyroxene cumulates. Chemical zoning in the pyroxenes has been imaged at 25-40 µm resolution using desktop microbeam X-ray fluorescence mapping followed up w...
