Alien Minerals Discovered at Ancient Meteorite Strike Site in Scotland by Katherine Hignett, Newsweek, Dec. 15, 2017 http://www.newsweek.com/skye-meteorites-alien-mineral-749103 60-Million-Year-Old Meteorite Impact Zone Discovered on Scotland’s Isle of Skye, Sci News, December 15, 2017 http://www.sci-news.com/geology/meteorite-impact-scotlands-isle-of-skye-05539.html “A team of geologists has found 60 million-year-old ejecta from a previously unknown meteorite impact on the Isle of Skye, northwest Scotland. This is the first recorded mid-Paleocene impact event in the region and is coincident with the onset of magmatism in the British Paleogene Igneous Province.” The open-access paper is: Drake, S.M., A.D. Beard, A.P. Jones, D.J. Brown, A.D. Fortes, I.L. Millar, A. Carter, J. Baca, and H.
