rhombohedrons

rhombohedrons

1. Their crystal structure sets them apart: calcite forms hexagons and aragonite forms rhombohedrons.

它们的结晶构造使它们分离：方解石型六角形和文石的菱面体。

5. 79. Quartz is commonly found as a six-sided, prism-shaped crystal topped by pyramid-like form, while calcite usually shows a crystal form of rhombohedron.

石英通常呈六方柱，顶上带有双锥的晶形，而方解石却常以菱形六面体形式出现。
