Beryllium-10 Study on the Origin of Tektites

Beryllium-10 Study on the Origin of Tektites

While looking for something else I came across an
interesting tektite study. It is;

Serefiddin, F., G. F. Herzog, and C. Koeberl, 2007,
Beryllium-10 concentrations of tektites from the
Ivory Coast and from Central Europe: Evidence for
near-surface residence of precursor materials.
Geochimica et Cosmochimica Acta. vol. 71, no. 6,
pp. 1574-1582 (March 15, 2007) doi:10.1016/j.gca.2006.12.007

To get the abstract of this article enter the above
doi number in the box at

they concluded:

"Although not definitive, consideration of several possible
cosmic-ray exposure histories suggests that about half the
interior 10Be has a meteoric origin, which if corrected to the
time of formation yields a concentration compatible with
those measured in typical contemporary soils. The observations
are consistent with the formation of three of the four main
tektite groups from surface soils or sediments."
