Volcanoes, Meteorites

5 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
