@article{oai:nipr.repo.nii.ac.jp:00001959, author = {Sutton, S.R.}, journal = {Memoirs of National Institute of Polar Research. Special issue}, month = {Jul}, note = {P(論文), The thermoluminescence characteristics of lunar meteorites Yamato-791197 and ALHA81005 are remarkably similar although not identical. Natural TL glow curves peak at a much higher temperature than the artificial glow curves, 350℃ vs. 150℃. The absence of low temperature natural TL is interpreted as resulting from shock heating during lunar ejection. The corresponding shock temperature is estimated to be 470±70℃ (1ms shock time) and the subsequent Earth transit times must have been less than 19000 and 2500 years for Y-791197 and ALHA81005,respectively. The principal difference between the two lunar meteorites is that the pre-ejection TL level of Y-791197 is a factor of 7 greater than that of ALHA81005 indicating that Y-791197 resided at a shallower, more heavily irradiated depth. Irradiation of both objects in the uppermost meters of lunar regolith with a vertical separation of meters would explain the results.}, pages = {133--139}, title = {Thermoluminescence of lunar meteorites Yamato-791197 and ALHA-81005}, volume = {41}, year = {1986} }
