4.4: Sedimentary Rocks
Rock gypsum is an evaporite rock that is composed of a single mineral, gypsum (CaSO 4 · 2H 2 O). Therefore, this rock has a predictable chemical formula and atomic structure. Rock gypsum is usually white or colorless with rhomb-shaped crystals or sometimes prismatic crystals. Rock gypsum is also very soft, and a fingernail can scratch its surface.

Environmental Efficiency Aspects of Basalt Fibers …
crushed basalt rock is supplied by a loader. Basalt melting takes place at a temperature about of 1500 C; however, unlike glass, dark basalt absorbs a substantially higher amount of infrared energy, which results in non-uniform distribution of temperature in the molten mixture [25]. In this regard, the melting period needs to be extended to ...
