With colleagues at UChicago (i.e. most of my dissertation committee), we revisited an oft studied sedimentary basin with excellent isotopic and textural preservation on the northern margin of the Lhasa terrane to reconsider the question of the timing of peneplanation (when the plateau became a plateaued surface) of the Tibetan Plateau. Our tome is now out in the American Journal of Science! Expect more of the Lunpola and organic geochemistry in the near future!  

New MS student, Hanna Leapaldt, has arrived! Hanna is interested in the interface of paleoclimate, policy, and society. She'll be working on improving our understanding of the lacustrine carbonate record of ancient climate by ground trotting proxy data in Fayetteville Green Lake (NY, USA). Welcome, Hanna!

A long time coming (2 year time series, to be exact): our paper on the interplay of microbial metabolisms, aqueous chemistry, and the carbonate record is out in Geobiology!

A collaborative effort led by Shanying Li (China University of Petroleum, Qingdao) on the effects of shallow burial on carbonate textures and stable isotopic compositions is now out in Sedimentary Geology! Here's a temporary open access link: https://authors.elsevier.com/c/1Z5r38RVhr7IU.

I am VERY excited to say that my paper investigating the effects of burial alteration on marine limestone, cements, and biogenic carbonates in orogenic basins is available now in GCA! I use an array of microanalytical techniques to identify textural and chemical alteration, and water-rock exchange and solid-state reordering modeling find the limits of what we can explain based on current knowledge of isotopic exchange behavior. Here's the link! https://www.sciencedirect.com/science/article/pii/S0016703719300821

Miquela will be joining the faculty in the Department of Geosciences at Penn State in 2020! We're actively recruiting masters and PhD students for Fall 2020. Students interested in carbonate alteration, the interplay of biology and chemistry in the formation of microbialite carbonate, and the sedimentary archive of alkaline lakes, please email Miquela!
