摘要
锌水绿矾产于陕西省南部红土石黄铁矿矿床氧化带。集合体呈钟乳状或皮壳状，单晶为短柱状和不规则粒状，极易溶于水。颜色为黄绿色或翠绿色。主要化学成分：ZnO16．35％，FeO8．86％，SO328．30％，H2O44．33％。分子式为（Zn，Fe）SO4·7H2O。主要X射线粉晶谱线是：0．4880（100），0．2739（80），0．5439（30），0．3225（30）和0．2476（30）um。它的化学成分和粉晶数据均与水绿矾（FeSO47H2O）或人工合成的锌水绿矾相似。
Zinc-melaterite occurs in the oxidation zone of pyrite ore deposits in southern ShaanxiProvince. The crystal aggregates are stalactitic or crustose in form and single crystals are shortprismatic or irregularly granular in shape. The mineral is yellow-green or jade-green in color. It iseasily water-soluble.Zinc-melaterite is composed mainly of ZnO (16. 35 % ), FeO (8. 86 % ), SO3, (28. 30% ) and H2O(44. 33% ). The molecular formula is (Zn, Fe )SO4. 7H2O. The strongest lines in the X-ray powderpattern are 0. 4880 (100), 0. 2739 (80), 0. 5439 (30) and 0. 3225 (30) and 0. 2476 (30) nm. Accordingto the Commissiori on New Mineral Names of the Chinese Mineralogical Association, the zinc-melaterite is similar to melarite (FeSO4. 7H2O) and synthetic zinc-melaterite [ (Zn, Cu) SO4.7H2O] in crystal structure, but is slightly different in chemical composition. The new mineral isa variety of zinc-melaterite.
