Orange‑toned scalenohedral calcite later precipitated and encrusted the stibnite matrix. Fine‑grained fibrous selenite fully covered the calcite layer afterward. Exposed calcite crystals are manually chiselled out from the outer selenite layer. This three‑stage paragenetic sequence records gradual shifts in hydro‑thermal fluid chemistry and displays a rare zoned‑type over‑growth structure.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003e辉锑矿‑方解石‑透石膏叠生矿物标本\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003e产地：中国云南大理巍山。热液矿脉内最先结晶产出辉锑矿。之后橙黄色犬牙状方解石析出并包覆辉锑矿基底。纤维状透石膏完整覆盖在方解石表层。如今裸露的方解石晶体，是人工剔除外部石膏层后显露出来。三段式依次共生生长，完整记录了成矿热液组分的变化，形成了稀缺的圈层叠生矿物构造。\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003eDimension : 10×7×4.7CM.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003eFREE shipping worldwide, shipping time 15-25 days.
