Abstract

14C in high-altitude rocks and in Antarctic meteorites of long terrestrial age has been found at levels consistent with in-situ production by cosmic rays. Levels of 0.2-0.59 dpm/kg (or 1.0-2.6 × 106 14C/g) are found in high-altitude samples ranging from 3300 to 5460 m. Similar values are observed in Antarctic meteorites that have been dated by 81Kr by Freundel, Schultz & Reedy (1986) as over 100 kyr old. -Authors
