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)?

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

In recent papers he was focusing on the following fields of study:

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.

Between 2014 and 2021, his most popular works were:

  • Destruction of the North China Craton in the Mesozoic (125 citations)
  • Preservation of Earth-forming events in the tungsten isotopic composition of modern flood basalts. (103 citations)
  • Tungsten-182 heterogeneity in modern ocean island basalts (101 citations)

In his most recent research, the most cited papers focused on:

  • Basalt
  • Igneous rock
  • Geochemistry

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.
