Volcanoes, Meteorites

6 May 2017

At https://phys.org/print413024026.html ... ancient meteorite impact sparked long lived volcanic eruptions on Earth is the claim. Not only can meteorites create craters but they can spark volcanic activity as well, according to a team of geochemists from Trinity College in Dublin. They dated rocks at the impact site, Sudbury in Ontario, some 1.85 billion years ago (way back in the uniformitarian past), when a massive bolide excavated a deep basin which was subsequently filled with melted rocks. On top of the impact evidence, they encountered a jumble of rocks with volcanic fragments. It was published in the Journal of Geophysical Research: Planets (2017) and the abstract can be read at http://onlinelibrary.wiley.com/doi/10.1002/2016JE005085/abstract
