回顾了U Th/He测年方法的发展过程 ,简要介绍了该方法测年的原理、分析流程和长α -粒子停止距离校正。然后介绍了近年来在磷灰石He扩散性研究及数值模拟方面取得的一些成果和磷灰石U Th/He热年代计在研究古地貌、岩体构造抬升、盆地热历史演化方面的应用。最后分析了U Th/He测年方法的优、缺点 ,说明这一方法既存在广阔的应用前景 ,又有待于进一步完善、提高。
The development of U Th / He dating method is reviewed. The principle of this method is briefly introduced, and the flow and long α - particle stop distance correction are briefly introduced. Then some achievements made in the research and numerical simulation of He diffusion of apatite in recent years and the application of apatite U Th / He thermochronometer in the study of paleogeomorphology, uplift of rock mass and the evolution of basin thermal history are introduced. Finally, the advantages and disadvantages of U Th / He dating method are analyzed, which shows that this method has broad application prospects and yet to be further improved and improved.
