Minerals are not equivalent to rocks. A rock is either an aggregate of one or more minerals, or not composed of minerals at all. Rocks like limestone or quartzite are composed primarily of one mineralâ calcite or aragonite in the case of limestone, and quartz in the latter case.or example, quartz is defined by its formula, SiO 2, and a specific crystalline structure that distinguishes it from other minerals with the same chemical formula (termed polymorphs). When there exists a range of composition between two minerals species, a mineral series is defined.

Cyanobacteria are arguably the most successful group of microorganisms on earth.
Cyanobacteria (English pronunciation: /saÉªËÃ¦noÊbÃ¦kËtÉªÉriÉ/; also known as blue-green algae, blue-green bacteria, and Cyanophyta) is a phylum of bacteria that obtain their energy through photosynthesis. The name cyanobacteria comes from the color of the bacteria (Greek: ÎºÏÎ±Î½ÏÏ (kyanÃ³s) = blue).
