A new technique for dating an antarctic meteorite by measuring the thermoluminescence (TL) growth on the meteorite surface is reported. The meteorite, an ordinary chondrite of the H-6 group, was determined to be 70,000 + or - 30,000 yr by Cl-36 dating and over 30,000 yr by C-14 dating. The depth variation of the TL intensity was observed and the surface temperature elevation and trap depth were estimated. The decay of the low-temperature glow was then estimated, and it was found that the low-temperature TL observed at the surface was due to radioactive irradiation received on the earth. The absorbed dose was determined, and the length of time to acquire that dose was calculated. If the meteorite was deeply buried in the ice sheet for most of its terrestrial history, the terrestrial age would be 41,000 + or - 7000 yr, in agreement with the radioactive age determinations.
