Shock-thermal history of Kapoeta howardite matter on data of thermoluminescence analysis of individual mineral grains

摘要

The artificially induced thermoluminescence (TL) was measured in OPx grains from Kapoeta howardite. The TL glow curves for individual OPx grains are significantly distinguished from each other both by their shape and TL sensitivity; five groups of OPx grains were characterized. The observed variety of glow curves of OPx grains could be caused by their distinct shock-thermal events at the regolith stage of meteorite parent body formation.
