On the basis of previous research achievements of measuring the solid state nuclear track in apatite by thermal analysis method, the author further proposes the research program to measure the energy deposited by the solid state nuclear track contained in zircon, sphene, epidote, apatite and other samples, in order to study the geological age and geothermal history. Compared with the measurement of nuclear track density by etching method, this one does not need to conduct so many processing programs for samples, but can improve the measurement accuracy.
A new measurement method of thermal analysis for solid state nuclear tracks is proposed.The annealing heat emitted by the unit mass of solid state nuclear tracks in heavy particles of the sample is determined via micro-thermal analysis method.Hence,the number of solid state nuclear tracks in the unit mass of sample is determined.In particular,this paper introduces the method and its significance to measure the number of α-particles nuclear tracks in apatite by measuring the annealing heat of α-particles nuclear tracks.In addition,the mechanism of the measurement and potential applications are discussed.
