Description
A coarse-grain granite that is composed of feldspar and quartz with some muscovite or biotite. Sometimes pegmatites may contains gem crystals (topaz, tourmaline, beryl, fluorite, apatite, garnet, lepidolite) and rare elements (uranium, tungsten, tantalum, boron, beryllium and lithium). Some pottery books formerly used the term 'pegmatite' as a synonym for Cornish granite and china stone.
