Abstract

Be, a cosmogenic isotope produced by cosmic rays interacting with the Earth ’s atmosphere and surface, has chemical and physical properties that make it useful as a tracer for some terrestrial processes and a geological clock for a few substances. The rarity of the stable isotope,

Be, allows
10
Be to be detected in natural materials at extremely low levels with backgrounds for rocks, sediments etc. below 105 atom g

now attainable, a value to be com pared with an average annual global deposition rate of 1.3 x 10

The affinity of Be for the components of soil and sediment is sufficiently high that its contact with them effectively immobilizes it, thereby allowing
10
Be to function as a tracer of sediment transport. The half-life of 1.5 Ma is convenient for some geological studies. Application has been found in cosmic-ray history, formation of manganese nodules, pelagic sedimentation, island-arc volcanism, soil evolution, soil erosion and rock weathering.
