Overview

What is he best known for?

The fields of study he is best known for:

  • Sedimentary rock
  • Igneous rock
  • Basalt

Richard Armstrong mainly focuses on Geochemistry, Zircon, Craton, Archean and Geochronology. His work in Geochemistry tackles topics such as Petrology which are related to areas like Quartz latite. Richard Armstrong interconnects Metamorphic rock, Granulite, Proterozoic, Basement and Pluton in the investigation of issues within Zircon.

His work deals with themes such as Foreland basin, Orogeny, Felsic, Sensitive high-resolution ion microprobe and Limpopo Belt, which intersect with Craton. His study looks at the relationship between Archean and topics such as Andesite, which overlap with Microprobe and Stratigraphy. His research integrates issues of Dharwar Craton and Terrane in his study of Geochronology.

His most cited work include:

  • Formation of an Archaean continent (603 citations)
  • Zircon ion microprobe studies bearing on the age and evolution of the Witwatersrand triad (316 citations)
  • Zircon ion microprobe studies bearing on the age and evolution of the Witwatersrand triad (316 citations)

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

Richard Armstrong mainly investigates Geochemistry, Zircon, Geochronology, Craton and Metamorphism. His Geochemistry research includes elements of Petrology and Proterozoic. His Proterozoic research includes themes of Provenance and Crust.

Zircon is a subfield of Paleontology that Richard Armstrong explores. His Geochronology study incorporates themes from Shrimp, Magmatism and Volcanic rock. His Metamorphism research incorporates elements of Orogeny, Granulite, Metamorphic facies and Recrystallization.

He most often published in these fields:

  • Geochemistry (72.51%)
  • Zircon (53.40%)
  • Geochronology (25.65%)

What were the highlights of his more recent work (between 2015-2021)?

  • Geochemistry (72.51%)
  • Zircon (53.40%)
  • Geochronology (25.65%)

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

His primary areas of study are Geochemistry, Zircon, Geochronology, Craton and Paleontology. The Geochemistry study combines topics in areas such as Sedimentary depositional environment and Shear zone. His study in Zircon is interdisciplinary in nature, drawing from both Metamorphism, Basement, Basalt, Gneiss and Archean.

His Geochronology research is multidisciplinary, relying on both Orogeny, Tectonics, Magmatism, Large igneous province and Igneous rock. The Igneous rock study combines topics in areas such as Proterozoic and Volcanic rock. The concepts of his Craton study are interwoven with issues in Earth science, Continental margin, Gondwana and Terrane.

Between 2015 and 2021, his most popular works were:

  • Deformation-induced trace element redistribution in zircon revealed using atom probe tomography (97 citations)
  • Mapping of bioavailable strontium isotope ratios in France for archaeological provenance studies (63 citations)
  • Improvement of laser ablation in situ micro-analysis to identify diagenetic alteration and measure strontium isotope ratios in fossil human teeth (38 citations)

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

  • Sedimentary rock
  • Basalt
  • Igneous rock

The scientist’s investigation covers issues in Zircon, Paleontology, Geochemistry, Geochronology and Craton. Richard Armstrong has included themes like Glacial period, Tectonic uplift and Dislocation in his Zircon study. His research on Geochemistry often connects related areas such as Sedimentary depositional environment.

His work deals with themes such as Felsic and Magmatism, which intersect with Geochronology. His Craton research integrates issues from Subduction, Back-arc basin and Gondwana. His biological study spans a wide range of topics, including Batholith, Brasiliano orogeny and Pluton.
