摘要
在捷克共和国扎杰洛夫附近的废弃采石场Milina，在巴兰地地区奥陶系沉积物中发现了一种非常罕见的磷酸盐allanpringite。褐斑岩形成黄色粉末和土质聚集体。在更详细的研究中，使用SEM显微镜，allanpruite形成棒状和板状晶体。其成因与萤光石的蚀变有关。allanpriite的经验公式为(Fe2.70Al0.24)Σ2.94(PO4)2.00(OH)2.83·5H2O，精炼后的单位胞参数为a 9.774(5)， b 7.361(3)， c 17.826(8) Å， β 92.2(6)°和V 1281.5(9) Å3。斑铜矿与黄钾铁矾、张纹石和部分蚀变的萤光石伴生。
Vzácný allanpringit - produkt alterace fluorwavellitu z lomu Milina u Zaječova (Česká republika)
A very rare phosphate allanpringite was found in the abandoned quarry Milina near Zaječov, Czech Republic in Ordovician sediments of the Barrandian area. Allanpringite forms yellow powder and earthy aggregates. In a more detailed study using SEM microscope, allanpringite forms rod-shaped and tabular crystals. Its origin is associated with alteration of fluorwavellite. Empirical formula of the allanprigite is (Fe2.70Al0.24)Σ2.94(PO4)2.00(OH)2.83·5H2O and refined unit-cell parameters are a 9.774(5), b 7.361(3), c 17.826(8) Å, β 92.2(6)° and V 1281.5(9) Å3. Allanpringite was found in association with jarosite, variscite and partly altered fluorwavellite.
