True Polar Wander and the Origin of the 800 Ma Bitter Springs Carbon Isotope Stage

First, field-based stratigraphic studies in Svalbard, Greenland, Victoria Island, and the Mackenzie Mountains (Canada) in collaboration with Galen Halverson, Matthew Hurtgen, David Jones (Harvard), and Robert Rainbird have revealed a pair of greater than 60 degree true polar wander events coupled to d13C and d34S excursions at about 800 Ma. The presence of TPW provides powerful additional constraints on paleogeography, and this realization has led to a new hypothesis for some of the observed d13C variablity during the Precambrian.
