Carbon Isotope Record from ~2.2 Ga Rocks in the Great Lakes Area
June 19, 2006 / Posted by: Shige Abe
Andrey Bekker of NAI’s Carnegie Institution of Washington Team and his colleagues have an article in press for Precambrian Research which details the carbon isotope record for the carbonate platform in the Great Lakes area. Observed carbon isotope values from the Lake Superior area may correspond to those from Griqualand West Basin, South Africa, supporting the notion of three global glaciations in the Paleoproterozoic Era.
