ML316 Prase

Code: ML316 名稱   綠蛋白石Name   Chrysoprase化學公式   SiO2Chemical Formula   SiO2莫氏硬度   6.0–7.0Mohs scale of Hardness   6.0–7.0描述 是玉髓(一種隱晶形式的二氧化矽)的寶石品種,其中含有少量的鎳。它的顏色通常為蘋果綠,但會變為深綠色。綠水晶蛋白酶的較暗的品種也稱為綠蛋白酶。 (但是,術語prase也用於描述包含亞氯酸鹽的石英,在一定程度上是顏色的描述,而不是嚴格定義的礦物品種。)Description is a gemstone variety of chalcedony (a cryptocrystalline form of silica) that contains small quantities of nickel. Its color is normally apple-green, but varies to deep green. The darker varieties of chrysoprase are also referred to as prase. (However, the term prase is also used to describe chlorite-included quartz, and to a certain extent is a color-descriptor, rather than a rigorously defined mineral variety.)小挑戰…

ML315 Scholzite

名稱  Name磷鈣鋅石Scholzite化學公式  Chemical FormulaCaZn2(PO4)2•2H2OCaZn2(PO4)2•2H2O  莫氏硬度  Mohs scale of Hardness  描述Description  Scholzite 是一種罕見的磷酸鋅礦物,來自德國巴伐利亞州哈根多夫的經典磷酸鹽礦物產地。 Hagendorf 地區包含一個富含磷酸鹽的偉晶岩侵入體,該侵入體經歷了一定程度的改變。稀有礦物如鋰長石是來自這個著名礦場的慷慨饋贈。 Scholzite 形成漂亮的亮白色板狀晶體,並與其他稀有磷酸鹽有關。當與其他稀有礦物結合時,標本會特別好。  Scholzite is a rare zinc phosphate mineral and comes from the classic phosphate mineral locality at Hagendorf, Bavaria, Germany. The Hagendorf locality contains a phosphate rich pegmatitic intrusive body that has undergone a certain amount of alteration. Rare minerals such as scholzite are a generous gift from this famous mineral site. Scholzite forms nice bright white tabular crystals and is associated with other rare phosphates. Specimens can be especially nice…
