Granite minerals |

On Vancouver beaches, granite (an igneous rock made up of different minerals) is often in the form granodiorite (black granite), which is speckled black, white, and grey/pink. Other common Vancouver beach rocks: smooth black rocks are likely to be basalt (igneous rock, cooled lava), and flat rough light brown rocks are likely to be sandstone (sedimentary rock made up of different minerals).

The minerals that are found in granite are primarily quartz, plagioclase feldspars, potassium or Kfeldspars, hornblende and micas. Quartz is usually the last mineral to crystallize and fills in the extra space between the other minerals. Quartz's hardness, lack of chemical reactivity and near lack of cleavage give granite a significant amount of its desirable durable properties.
