Description

There were supercontinents before Pangea known as Rodinia and Nuna. Because Laurentia (ancient North America) was central to Rodinia and Nuna, understanding its position is crucial to our knowledge of previous supercontinents. However, currently there is a gap in the record on Laurentia’s location from ~1.3 to 1.1 billion years ago (Ga). Donald Elston of the U.S. Geological Survey studied Mesoproterozoic (1.6 Ga - 1 Ga) red beds to help fill the gap in Laurentia’s record. However, his research faces several issues, including inadequate demagnetization methods and unpublished data (1). The purpose of this research is to analyze new samples from the Grinnell Formation and the Hakatai Shale that will allow for a new evaluation and modernization of Elston’s data.
