Accurate determination of large ion lithophile elements, high field strength elements and rare earth elements in granite pegmatite can be used to judge the source of ore-forming fluid materials and the diagenetic tectonic environment. There are some problems in the sample determination process, such as incomplete decomposition of insoluble minerals and low recovery of elements like Zr, Hf, Th, U and rare earth elements. This article compared the decomposition effects of three methods. The results indicate that the two open digestion methods can lead to lower test results for elements such as Zr, Hf, and W, etc. In the closed digestion method,
