Abstract: Abstract Neoproterozoic kimberlite, ultramafic lamprophyre, and carbonatite magmatic activity was widespread across the Canadian-Greenland Shield. Models to explain the preponderance of this deeply-derived CO 2 -rich magmatism between 680–540 Ma range from impingement of multiple mantle… read more here.
