Overview

Julian S. Marsh is affiliated with Rhodes University in South Africa and has contributed extensively to the field of Earth and Planetary Sciences, with a focus on geophysics and geology. Their research spans various subfields including geophysics, geology, artificial intelligence, paleontology, and atmospheric science.

Their recent work includes several papers published in notable scientific venues. These include:

  • 40Ar/39Ar geochronology of the Drakensberg continental flood basalts: Understanding large argon isotopic variations in mafic groundmass and plagioclase size fractions (2022, Chemical Geology)
  • Petrogenesis of the Tuli Basin high-Ti picrites and basalts, Karoo CFB, southern Africa: Classification, stratigraphy, emplacement, and mantle source heterogeneity (2023, Lithos)
  • Co-existing low-Ti and high-Ti dolerites in two large dykes in the Gap Dyke swarm, southeastern Karoo Basin (South Africa) (2020, South African Journal of Geology)
  • Misrepresentation of early Karoo Volcanism: A critical discussion of aspects of "De Wit et al., 2020. Pillow talk: Volcanic rocks of the Karoo that formed many leagues under the Gondwanan Sea." (2020, South African Journal of Geology)
  • Unravelling the effects of crustal assimilation versus mantle source heterogeneity in Tuli basin picrites, Karoo LIP (2021, Goldschmidt2021 abstracts)

The scientist's publications concentrate largely on geological and geochemical analysis, geochemistry and geologic mapping, as well as geological and geophysical studies. Other relevant topics in their work include paleontology and stratigraphy of fossils, geological studies and exploration, high-pressure geophysics and materials, and earthquake and tectonic studies.

Frequent collaborators in their work include Geoffrey H. Howarth, Clémentine Antoine, Richard Spikings, Urs Schaltegger, and Chris Harris.

The main venues where their work is published cover a range of prominent journals and conferences such as:

  • Goldschmidt2021 abstracts
  • South African Journal of Geology
  • Chemical Geology
  • Lithos
  • The CASE Journal

The scientist's research contributes to understanding mantle source heterogeneity, volcanic rock formation, and geochronological techniques applied to geological formations originating in the Karoo Basin and Drakensberg flood basalts. Their body of work reflects interdisciplinary approaches combining geological fieldwork, geochemical analyses, and geochronological dating methods to address complex earth science questions.
