铀系国际标准样的鉴定是开展铀系方法的一项基础工作。其主要内容是测定实验流程中所必需使用示踪剂的参数,测试地质样品中各项同位素比值和年龄,检验各国铀系实验室的全部实验程序。 1975年在美国地质协会彭罗斯(Penrose)全新世—更新世年代学会议上和第一届迈阿米(Miami)同位素气候学和古气候学会议上,曾倡议开展铀系各实验室之间的国际对比。1976年初由Harmon等举办了第1阶段铀系国际标准样对比计划(USIP—Ⅰ),有
The identification of uranium-based international standards is a basic undertaking for the uranium-based approach. Its main content is the determination of tracer parameters necessary for the experimental process, testing of geological samples isotope ratio and age, testing all uranium laboratory in all countries experimental procedures. In 1975, at the Holocene-Pleistocene-Geochronology Conference of the Geological Association of Penrose in the US Geological Association and the first conference on isotope climatology and paleoclimatology in Miami, International comparison. The first phase of the uranium series International Standard Sample Comparison Program (USIP-I) was held by Harmon et al. In early 1976. There are
