Late Cambrian-Early Ordovician Stratigraphic Paleobio
Exploring the sedimentologic and stratigraphic context of abrupt biotic turnover in the Late Cambrian-Early Ordovician part of the Sauk Sequence. Emphasis is on present-day western margin of Laurentia. Project led by Jonathan Adrain at the University of Iowa and in collaboration with Steve Westrop, Carl Brett, and Ben Datillo.
Eocene of Egypt
Sequence stratigraphy and stratigraphic paleobiology in the Bartonian-Priabonian of Wadi al-Hitan, in collaboration with Philip Gingerich, Univ. of Michigan. Some of this work is described in Peters et al. (2009) Palaios, in Peters et al. (2010) Geology, and in Gingerich et al (2012) Geology.
Cambrian of Montana
Carbonate sedimentology, chemostratigraphy, and sequence stratigraphy of the Sauk Sequence (mostly Drumian) in the Bob Marshall Wilderness of NW Montana. Aspects of this work are described in Tim Foltz's Masters thesis and in this GSA Abstract.
Carbonate cement geochemistry
Ben Barnes, former M.S. student, characterized the composition and stable isotope geochemistry of carbonate disseminated in the Bakken Formation. The goal was to develop a formation-scale estimate of the mass and composition of this potentially volumetrically significant and isotopically distinct carbonate sink. Sampling was done at the USGS core lab. This work has now been published in Sedimentology.
