Recent research highlight:
Open-access paper by recent PhD graduate Nabil Shawwa on the hunt for primary evidence of terrestrial Fe oxidation in 2.3-billion-year-old red beds of the Huronian Supergroup: Shawwa et al. (2024). |
We are Earth historians armed with acids and mass spectrometers
Our research group uses most elements on the periodic table as geochemical "fingerprints" to understand natural processes in Earth's systems. We study the element abundances and isotope ratios of rocks, sediment, waters, and sometimes biological and synthetic materials. Currently, we focus on understanding Earth surface processes that transfer elements from land to sea in dissolved and particulate forms. We are interested in how these Earth surface processes evolved through geological time, mainly as a function of changing climate and atmospheric redox state, and how specific rock types controlled the supply of specific elements to the hydrosphere. We specialize in measuring elements at ultra-low abundances (sub-parts per million in rocks, sub-parts per billion in waters), such as W, Mo, Ta, Hf, Tl, Cs, and Li, with the aid of cutting-edge analytical workspaces.
