Scolecite

斯科利特

This large sample of scolecite is displayed in the Smithsonian Museum of Natural History. It is about 50 cm across and is from Nasik, Maharashtra, India. Each elongated needle is a crystal whose shape reflects the chainlike arrangement of its atoms. The cluster grew from a water solution that filled a gas bubble in cooled volcanic rock. Workers discovered it while quarrying. Scolecite is a silicate mineral with the composition CaAl₂Si₃O₁₀.3H₂O

这种大型的 scolecite 晶体陈列在史密森尼自然历史博物馆中。它宽约 50 厘米，来自印度马哈拉施特拉邦的纳西克。每个细长的针状物都是一个晶体，其形状反映了其原子的链状排列。这一簇是在冷却的火山岩中充满气体气泡的水溶液中生长而成的。工人在采石时发现了它。scolecite 是一种含硅酸盐的矿物，化学式为 CaAl₂Si₃O₁₀·3H₂O。
