Pectolite
佩克利特
NaCa2(HSi3O9)
NaCa₂(HSi₃O₉)
These samples of pectolite are displayed in the Smithsonian Museum of Natural History. Pectolite is an silicate mineral of calcium and sodium. It has the composition NaCa2(HSi3O9). The rounded specimen has a diameter of about 11 cm wide and is from Prospect Park, New Jersey.
这些佩克利特标本陈列在史密森尼自然历史博物馆中。佩克利特是一种含钙和钠的硅酸盐矿物，其化学式为NaCa₂(HSi₃O₉)。该圆润的标本直径约为11厘米，来自新泽西州的Prospect Park。
From the museum's description: "The rounded shape of pectolite comes from many crystals crowding together like seeds on a dandelion. You can see some in the broken area of the specimen. The other rounded, or botryoidal, specimens formed in much the same way."

从博物馆的描述来看：‘佩克利特的球形结构源于许多晶体相互拥挤在一起，就像蒲公英种子一样。你可以在标本的破碎区域中看到一些这样的结构。其他球形或葡萄状的标本也是以类似的方式形成的。
