Electron microprobe data for monazite and xenotime used in consideration of gold deposit formation models
Electron microprobe geochemical data that is used to showcase differences in phosphates when derived from magmatic-hydrothermal systems compared to metamorphic-hydrothermal systems to improve understanding of the mechanisms by which some mineral deposits were formed. Data are provide in CSV format. |
