Mineralogy and petrology of alkaline rocks and carbonatites: Celebrating the life and work of Gregory Yu. Ivanyuk (1966–2019)

“…Burbankite is considered a primary magmatic constituent of calcite carbonatites, which was replaced at late hydrothermal stages by a complex assemblage of Ba-Sr-REE minerals. Le Bras et al (2021) applied micro-focus X-ray computed tomography to investigate sulfide-rich phoscorites and carbonatites from the Phalaborwa complex, South Africa. Their data show that three-dimensional textural analysis is effective for the characterisation of magma flow and understanding of the processes that control sulfide mineralisation (bornite, chalcopyrite, cubanite and valleriite) in phoscorites and carbonatites.…”
