The application discloses a yellow-fruit Machilus cpSSR molecular marker, a primer group and application thereof, and belongs to the technical field of molecular markers. The cpSSR molecular marker comprises molecular markers CP09, CP32, CP33, CP35, CP54 and CP59, and is obtained by amplification of a primer group shown in SEQ ID NO. 1-12. The cpSSR molecular marker can be used for genetic diversity, genetic differentiation and population structure analysis of different species of the yellow-fruit Machilus, can make the genetic background clearer, can provide a theoretical basis for subsequent in-depth research on Machilus genetic relationship identification, population dynamics and phylogeography, and can provide technical support for efficient utilization and protection of the yellow-fruit Machilus germplasm resources.

This invention discloses a genetic discrimination method for sedimentary bauxite based on gallium / lithium elemental distribution, belonging to the field of genetic discrimination technology. This method establishes a multi-dimensional geochemical index system, including gallium-titanium ratio, gallium weathering ratio, and lithium content, and solidifies specific quantitative threshold standards for three types of deposits: allochthonous weathering, in-situ sedimentary, and sedimentary-leaching altered deposits. It boasts high discrimination accuracy and effectively solves the technical problems of ambiguity, multiple solutions, and high misjudgment rate caused by traditional methods relying on field macroscopic observation and subjective experience. Furthermore, based on cluster analysis and discriminant analysis algorithms, it solves for the optimal classification interface in the multi-dimensional parameter space, compiling a gallium-lithium dual-element collaborative discrimination chart and a regionally specific genetic type quantitative standard table, significantly improving the scientific rigor of bauxite mineralization regularity research and the efficiency of mineral exploration.
