Stibnite‑Calcite‑Selenite Epigenetic‑Growth Specimen D sales Some yellow minerals penetrate intoStibniteCalciteSelenite EpigeneticGrowth Specimen from Weishan YiHui Autonomous County, Dali, Yunnan Province, China Primary stibnite crystals crystallized first within the hydrothermal vein. Orangetoned scalenohedral calcite later precipitated and encrusted the stibnite matrix. Finegrained fibrous selenite fully covered the calcite layer afterward. Exposed calcite crystals are manually chiselled out from the outer selenite layer. This threestage
