摘要在德国拉姆斯贝克附近的巴斯滕贝格矿场，在一块板岩标本上涂上一层蓝绿色的鳞片状涂层，产生了类似于舒伦贝利石的X射线粉末图案。从化学上讲，它是舒伦贝利石的锌类似物。电子探针数据、X射线荧光光谱和电感耦合等离子体发射光谱分析显示了两种不同的富锌成分。热重分析和CHN结果表明，该相可能含有3-4个水分子。粉末数据在一个六角形晶胞上进行索引，晶胞体积为431.6(2)ä，c 7.247(4)ä，Z=1。
Abstract A blue-green scaly coating on a slaty specimen from the Bastenberg mine, near Ramsbeck, Germany, yielded an X-ray powder pattern akin to schulenbergite. Chemically it is the zinc analogue of schulenbergite. Electron-probe data, XRF and ICP/OES analyses are presented which demonstrate two distinct zinc-rich compositions. Thermogravimetric analysis, together with CHN results, suggest the phase may contain 3-4 water molecules. Powder data are indexed on a hexagonal cell with a 8.293(2) Å, c 7.247(4) Å and cell volume 431.6(2) Å3, with Z = 1.
