Overview

What is he best known for?

The fields of study he is best known for:

Basalt
Igneous rock
Geochemistry

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 most cited work include:

Re-Os Ages of Group IIA, IIIA, IVA, and IVB Iron Meteorites (1017 citations)
THE Re-Os ISOTOPE SYSTEM IN COSMOCHEMISTRY AND HIGH-TEMPERATURE GEOCHEMISTRY (760 citations)
Carius tube digestion for low-blank rhenium-osmium analysis (734 citations)

What are the main themes of his work throughout his whole career to date?

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.

He most often published in these fields:

Geochemistry (62.22%)
Mantle (35.23%)
Meteorite (20.74%)

What were the highlights of his more recent work (between 2014-2021)?
