遵义牛蹄塘组黑色岩系发现的多水硫磷铝石主要产出在Ni-Mo多金属层的微裂隙中，偶尔在多金属层下部的黑色粉砂岩中以脉体形式产出。该矿物结构不稳定，结构中一部分水分子很容易失去，在X射线衍射鉴定时其特征谱线变化较大；在自然条件下存放一定时间后，样品具有稳定的X射线衍射特征。此外，对这些样品进行了红外光谱、热重和差热分析、TEM观测、化学分析和晶胞参数计算，与纤磷铝石进行了对比和讨论。 |

Sasaite from Niutitang black shales at Zunyi occurs mainly as micro-fissures in Ni-Mo multi-metal mineralization strata, and also as small sasaite veins in black shales beneath the Ni-Mo multi-metal mineralization strata. Part of structure water in sasaite is easy to lose, leading to a variety of XRD spectra, and steady XKD spectra can be kept after the samples have been preserved for long under natural conditions. IR spectra, DG-TGA, TEM and chemical composition of the sasaite have been determined, and relative crystal cell parameters have been calculated from the XRD data; the difference between sasaite and vashegyite has been discussed. |
