| 摘 要： | 活动构造研究、近现代火山研究、古地磁研究等要求K-Ar和Ar-Ar年代学方法不断向越来越小的年龄尺度和越来越精细的方向发展。文中以腾冲等火山地区的K-Ar和Ar-Ar年代学研究结果及实验方法研究结果为根据,对K-Ar和Ar-Ar方法的精细测年及其检验进行阐述。说明K-Ar和Ar-Ar年代测定结果是单个样品的单次测量结果,其影响因素包括样品因素和实验因素。为了提高测年结果的准确度和精确度,必须有严格而合理的野外采样和实验过程,并且在具体的地质样品年代测量之外,还应经常利用一系列可能的方法对实验结果进行检验

| Abstract: | The K-Ar and Ar-Ar dating methods are the developed methods and widely applied to various geosciences fields. Study on the active tectonics, latter-day volcanoes and paleo-geomagnetism requires that the K-Ar and Ar-Ar methods should be developed towards the accurate dating and small time-scale. In recent years, geologists have paid much attention to dating the Tongchang volcano, Changbaishan volcano and Wadalianchi volcano in China and acquired many achievements. So it is practically significant to study a. |
