Geoscience Data Journal, Volume 11, Issue 4, Page 538-549, October 2024.In this study, we use pXRF to analyze major and trace elements in Qiaomaishan copper‐sulphur ore cores. The finding shows that the abundance changes of Fe, Cu, S, and W are closely related to the distribution of ore bodies in the borehole bar chart. Abstract Drilled cores provide first‐hand data for deposit research.
