摘要：
The apatite has the lowest available He closure temperature (about 70℃); the 4He concentration profile is a very rich source of information on an apatite's low temperature (30~90℃) cooling history. According to classical diffusion theory, the 4He/3He thermochronometry technique in which the natural spatial distribution of 4He is constrained using a mathematical technique in a sample containing synthetic, proton-induced 3He. The approach is useful for constraining the low temperature cooling histories of individual samples. The review gives the fundamental theory, simulation method, the example application of this thermochronometry technique and the potential applications. Although this technique is in the exploration, but the sensitivity of the low-temperature cooling history makes this method have broad prospects. ©, 2014, State Seismology Administration.
