I am a co-author on a paper led by Brian Kelley, titled Controls on carbonate platform architecture and reef recovery across the Paleozoic to Mesozoic transition: A high-resolution analysis of the Great Bank of Guizhou, published in Sedimentology. The figure above highlights the description of the first reef metazoans (sponges, Sp) in a microbial framework (Tubiphytes, Tb) after the end-Permian extinction. A link to the paper is here.

Today's special issue in Geochimica et Cosmochimica Acta has two publications to highlight. The first is a reactive transport model of uranium isotopes in marine reducing environments that was started as a Ph.D. project and completed as part of my postdoc: Uranium reduction and isotopic fractionation in reducing sediments: Insights from reactive transport modeling. The model allows us to explore the important depositional factors that ultimately control seawater uranium isotopes. Check out the figure below and download the PDF here. 

Feifei Zhang and colleagues also have published a review on the uranium isotope proxy in carbonates, titled Uranium isotopes in marine carbonates as a global ocean paleoredox proxy: A critical review. You can download the PDF here.

I am so pleased to welcome Kaitlin Taylor (M.S. student) and Fai (Watsawan) Chanchai (Ph.D. student) to the group. Kaitlin and Fai join Bri McMaster Smith, a B.S. candidate from the University of Wyoming who has been an undergraduate researcher in the lab for the past year. I am excited for all of the science to come!
