2009 - Fellow of American Geophysical Union (AGU)
Richard J. Walker mainly investigates Geochemistry, Mantle, Chondrite, Meteorite and Basalt. His work on Enstatite expands to the thematically related Geochemistry. The Mantle study combines topics in areas such as Isotopic composition, Outer core and Mineralogy.
His Chondrite research is multidisciplinary, incorporating perspectives in Cosmochemistry, Rhenium and Breccia. His Meteorite study is associated with Astrobiology. His Xenolith course of study focuses on Lithosphere and Craton, Metasomatism, Proterozoic and Archean.
His main research concerns Geochemistry, Mantle, Meteorite, Chondrite and Basalt. His Archean, Crust, Radiogenic nuclide, Ultramafic rock and Peridotite study are his primary interests in Geochemistry. His work carried out in the field of Mantle brings together such families of science as Mantle plume, Ophiolite, Trace element and Olivine.
His Meteorite research integrates issues from Isochron and Analytical chemistry. His Chondrite research is multidisciplinary, relying on both Rhenium and Isochron dating. His Basalt research includes themes of Volcano and Igneous rock.
His primary areas of study are Geochemistry, Mantle, Meteorite, Astrobiology and Basalt. His research ties Ophiolite and Geochemistry together. His Mantle study combines topics in areas such as Flood basalt, Trace element and Mineralogy.
His Astrobiology research includes elements of Earth science and Core formation. His research in Basalt intersects with topics in Volcano, Mantle plume and Terrane. Richard J. Walker combines subjects such as Olivine, Regolith and Analytical chemistry with his study of Chondrite.
The scientist’s investigation covers issues in Geochemistry, Mantle, Basalt, Meteorite and Archean. His Geochemistry study combines topics from a wide range of disciplines, such as Lithosphere and Proterozoic. Richard J. Walker has researched Mantle in several fields, including Astrobiology, Solar System and Metal.
Richard J. Walker usually deals with Basalt and limits it to topics linked to Terrane and Hotspot and Paleoarchean. He has included themes like Glacial period, Isochron, Continental crust and Diamictite in his Archean study. His Chondrite research includes elements of Regolith and Analytical chemistry.
