Whole-rock geochemical data of the sedimentary rocks of the lower Cambrian Qiongzhusi Formation, the Yinmachi section, central Yunnan

Specifically, it includes tables for major element content (Table 1), trace element content (Table 2), rare earth element content (Table 3), as well as detailed calculation steps for relevant parameters. The testing work of whole rock geochemical elements was entrusted to Guangzhou Ausilicon Mineral Laboratory.

Before testing, the rock samples were systematically pre processed. The specific process is as follows: first, the original rock samples are put into a small crusher for preliminary crushing, and then the crushed rock particles are further crushed in a tungsten carbide mortar and a vibrating crusher until the sample particle size reaches below 200 mesh to meet the experimental requirements of subsequent element content testing.
