Boron cosmochemistry. Part I: Boron in meteorites
Abstract Thirty‐six fragments of meteorite falls, never touched by water or other possible sources of B contamination, were analyzed for B by prompt gamma‐ray neutron activation analysis at McMaster University and at the U.S. National Institute of Standards and Technology. Boron concentrations are c...
