Oman contains stunning and well-preserved carbonate rocks recording the ocean conditions during the Ediacaran period. The Fara Formation of Oman has presented me with the opportunity to understand basinal ocean conditions during the late Ediacaran period through stable isotope analysis, sedimentology, and petrography. I'm also interested in better apportioning time through the Ediacaran succession exposed in Oman using a variety of geochronological techniques. 



The siliciclastic succession above and below the strata of the Gaskiers glaciation exposed in Newfoundland offer an opportunity to understand climate and ocean conditions prior to the emergence of the first animals. 


California (Death Valley area)

My work near Death Valley has focused on unusual carbonate precipitates, and the detrital zircons contained in them, within the Johnnie Formation, an Ediacaran mixed siliciclastic-carbonate unit thought to record the Shuram Excursion. 


This island chain in the Arctic Circle preserves some amazing sedimentary rocks from the Cryogenian and Ediacaran periods. Fieldwork here requires careful attention not only to the rocks but also the wildlife, which includes polar bears.
