Bornhardts can form in any type of plutonic rock but are typically composed of granite and granitic gneiss. Granite domes are domical hills composed of granite with bare rock exposed over most of the surface. Once the granite deposit is exposed open cast mining is the usual way to exploit the reserves. Gneiss is a metamorphic rock formed by changing schist, granite, or volcanic rocks through intense heat and pressure. Step 2 The granite blocks are transported to facilities where they will be cut down into slabs. How is quartz formed? As the magma rises to Gneiss is foliated, which means that it has layers of lighter and darker minerals. They are crystallized by felsic melts that are less dense than mafia rocks and therefore tend to ascend to the surface.
