His primary scientific interests are in Geochemistry, Basalt, Mantle, Mineralogy and Anorthosite. John Longhi performs integrative study on Basalt and Liquidus in his works. His research in the fields of Mid-ocean ridge overlaps with other disciplines such as Partition coefficient and Solidus.
His Mid-ocean ridge study incorporates themes from Petrology and Archean. His Mineralogy research focuses on Pyroxene in particular. His work in Anorthosite addresses issues such as Massif, which are connected to fields such as Mafic, Transition zone, Crust, Magma and Continental crust.
His primary areas of investigation include Geochemistry, Mineralogy, Basalt, Petrology and Olivine. His Geochemistry research includes elements of Anorthosite and Proterozoic. His work investigates the relationship between Mineralogy and topics such as Thermodynamics that intersect with problems in Diopside.
His Basalt study combines topics in areas such as Martian and Magma chamber. His Petrology research integrates issues from Petrography, Igneous rock, Pluton and Crust. His Olivine research is multidisciplinary, incorporating perspectives in KREEP, Augite, Partial melting and Analytical chemistry.
The scientist’s investigation covers issues in Geochemistry, Proterozoic, Magma, Petrology and Pyroxene. His study ties his expertise on Anorthosite together with the subject of Geochemistry. His Anorthosite research is multidisciplinary, incorporating elements of Fractional crystallization, Basalt, Labradorite, Pluton and Andesine.
His research integrates issues of Metamorphism, Felsic, Mafic and Partial melting in his study of Archean. His KREEP research incorporates elements of Lunar magma ocean, Olivine, Norite and Peridotite.
