Induced thermoluminescence(TL)properties of Chinese 11H
6L and 3LL chondrites have been measured.TL peak temperature and peak width are 163-206℃
Av.and 83-137℃ for H chondrites
183-203℃
and 111-143℃
for L and LL
respectively. Recently fallen Chinese ordinary chondrites have TL peak width generally smaller than those of ordrinary chondrites from other regions.Based on our TL sensitivity data and published noble gases data
a 3He exposure age/21Ne exposure age-Induced TL sensitivity-4He gas retention/40Ar gas retention diagram is introduced. This type of diagram is a powerful tool for distinguishing different thermal histories of meteorites.
