普通铅法是铅同位素地质年代学的一个重要部分。与其他计时方法相比,普通铅法在样品采集、分选、化学处理和质谱测定等方面都显得较为简便,它不仅可以用于测定地质体和天体的年龄,而且是探索其物质来源和成因信息的重要工具,因此,虽然这种方法 The common lead method is an important part of the geochronology of lead isotopes. Compared with other timing methods, the common lead method is simple and convenient in sample collection, sorting, chemical processing and mass spectrometry. It can not only be used to determine the age of geologic bodies and celestial bodies, but also to explore the sources and causes of the materials Information is an important tool, therefore, although this approach
