Overview

Michael J. Melchin is affiliated with St. Francis Xavier University in Canada and has contributed extensively to the field of Earth and Planetary Sciences. Their research spans various domains, including paleontology, atmospheric science, geophysics, geology, and ecology.

Their work often focuses on the paleontology and stratigraphy of fossils, geology and paleoclimatology research, geological and geochemical analysis, isotope analysis in ecology, geological formations and processes, geological and geophysical studies, and geochemistry and elemental analysis.

Melchin has several recent publications, including:

  • A long-term record of early to mid-Paleozoic marine redox change (2021) in Science Advances
  • The Sedimentary Geochemistry and Paleoenvironments Project (2021) in Geobiology
  • The Road River Group of northern Yukon, Canada: early Paleozoic deep-water sedimentation within the Great American Carbonate Bank (2020) in Canadian Journal of Earth Sciences
  • Decoupling δ13Ccarb and δ13Corg at the onset of the Ireviken Carbon Isotope Excursion: Δ13C and organic carbon burial (forg) during a Silurian oceanic anoxic event (2020) in Global and Planetary Change
  • A high-resolution record of the late Hirnantian to Aeronian marine redox change in South China and its relationship with the record of graptolite biodiversity (2023) in Palaeogeography Palaeoclimatology Palaeoecology

Frequent co-authors in their research include:

  • Justin V. Strauss
  • Erik A. Sperling
