岩石矿物中钾的测定,目前大多数实验室都采用火焰光度法。该法虽然简单快速,但是准确度较差。部颁岩石矿物分析钾测定允许偶然误差范围较大,就充分说明了这个问题。采用这种方法所获得的结果,能满足地质科研,生产的一般要求,但难于满足某些方面的特殊要求。随着地质年代学的 Determination of potassium in rock minerals, most laboratories are using flame photometry. Although the law is simple and fast, but the accuracy is poor. The ministerial analysis of potassium in rock minerals allows a large range of accidental errors to fully explain this issue. The results obtained by this method can meet the general requirements of geological research and production, but it is difficult to meet some special requirements. With the geochronology
