Name:
Daniel Moreau Barringer (May 25, 1860, Raleigh, North Carolina, USA – November 30, 1929, Philadelphia, Pennsylvania, USA), early proponent of the meteor impact origin of Meteor Crater, Canyon Diablo, Arizona, USA.
"The Ollague meteorite, as a whole, was artificially annealed at a temperature above 1000°C and that heating gave rise to secondary high-temperature alteration of chemical and phase compositions of this meteorite, including the formation of barringerite." (from Britvin et al 2017).
