What minerals are found as inclusions in quartz?
Tourmalinated quartz are crystals of quartz that have inclusions of tourmaline in the quartz. When the quartz crystals grow, there are often inclusions of other minerals and the solutions from which the crystals grew ( fluid inclusions can be used to tell the conditions under which the crystal grew). Common minerals which occur with quartz include rutile, hematite, micas, actinolite, and riebeckite. A number of varieties are named for specific inclusions such as rutilated quartz ( rutile), Venus hair stone ( rutile), Thetis hair stone ( actinolite), and Cupid’s darts ( tourmaline). Inclusions can also show a younger stage of growth inside a crystal as a phantom within the crystal. See also article on varieties of quartz.
