The Search for Meteorites with Complex Exposure Histories Among Ordinary Chondrites with Low He-3/Ne-21 RatiosWe present concentrations of cosmogenic radionuclides in 15 ordinary chondrites with low He-3/Ne-31 ratios. We identified only one or two meteorites with a complex exposure history, whereas the others are consistent with single-stage exposures. Additional information is contained in the original extended abstract.
