Scientists from NAI’s UCLA and University of Colorado, Boulder Teams recently published their new geologic and geochemical analysis of the ancient rocks on Akilia Island in West Greenland which were the subject of a controversial Nature paper ten years ago. This new study includes a thorough geologic map of the area, and, using the ion-microprobe to analyze carbon inclusions in the rock, outlines a carbon isotopic ratio indicative of life’s signature. Their work appears in the current issue of the American Journal of Science.
