Quartz is silicon dioxide, SiO2. Quartz is abundant in the Earth's crust, being the chemically simplest form of the silicates. Microcrystalline quartz rocks are collectively called chert, but varieties of chert are given other specific names. One of the distinctive varieties of quartz is called jasper. The sample at right is about 12x15 cm and is from Erzgebirge, Sachsen, Germany. All the samples here are displayed in the Smithsonian Museum of Natural History. 石英是二氧化硅，SiO₂。石英在地壳中很丰富，是硅酸盐中化学最简单的形式。微晶石英岩石统称为石英岩，但石英岩的种类有其他特定名称。石英的一种显著种类称为 Jasper。右侧的样品约为12x15厘米，来自德国萨克森的埃尔茨贝格。所有这些样品均陈列在史密森尼自然历史博物馆中。
