Caption

Colored and black points mark seafloor with ages of 66 Ma that was created at spreading rates above and below 35 mm/yr, respectively. Colors indicate the maximum gravity anomaly within 2 degrees. This material relates to a paper that appeared in the 07 Feb. 2018, issue of Science Advances, published by AAAS. The paper, by J.S. Byrnes at University of Minnesota in Minneapolis, Minn., and colleagues was titled, "Anomalous K-Pg-aged seafloor attributed to impact-induced mid-ocean ridge magmatism."
