In this contribution, Δ47/U-Pb thermochronometry of calcite veins from the SPFT are combined with fracture analysis, fluid-inclusion microthermometry and thermal modelling to define the temperature and timing of vein formation, and to unravel the origin of calcite-precipitating fluid within the tectonic frame of the area.
Home – Cherokee Ruby Mine
About the Cherokee Ruby Mine. The Cherokee Ruby and Sapphire Mine is a "placer" gem mine. The term "placer" refers to mineral bearing deposits of ancient sand, dirt, and gravel which were left behind by ancient glaciers, rivers, or other flowing waters, also known as "alluvial deposits".
Ore Generation
An example of this would be finding Small Ruby or Small Cinnabar Ore vs. Small Redstone Ore in the overworld. Ruby and Cinnabar never generate as a global ore but Redstone does, thus a Small Redstone Ore on its own doesn't necessarily mean there's a Redstone Vein nearby, while seeing a Small Ruby or Small Cinnabar does indicate a …
