Quartz | Common Minerals

Quartz veins are also important host rocks for gold and other precious metals, and were the target of many mining 'rushes'. From a historic perspective, however, the single most important use of quartz may have been to start fires. When chert is struck against iron, it produces a relatively long-lived spark. From prehistoric times on, this has been one of the most reliable
