Neoproterozoic to Cambrian Strata of Central Transantarctic Mountains
Work done with John Goodge (U. of Minnesota, Duluth) in 1999 and 2000 resulted in a number of publications that covered aspects of sedimentology, stratigraphy, structural geology, thermochronology, and detrital zircon geochronology. Our detrital zircon data suggested that there was an extension of the Laurentian 1.4 Ga anorogenic belt of granitic intrusive bodies that exists under the ice in Antarctica. Goodge et al. (2008) provided strong evidence for this idea in the form of a granitic boulder of similar age and chemistry from modern till, cementing the hypothesis of a Laurentian–Antarctic connection within the supercontinent Rodinia.
I returned to Antarctica in 2012, working with Lars Holmer (Sweden) and colleagues (Glen Brock, Lars Stemmerik, and Christian Skovsted). This work is a more detailed paleontological study of Lower Cambrian strata.
