Feldspar
Feldspars (KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8) are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight.

Gneiss
Gneiss is a common distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks.

Metamorphic rock
Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form".

Mineral and Lapidary Museum
The Mineral and Lapidary Museum of Henderson County is a non-profit, volunteer-run museum in Hendersonville, North Carolina founded in 1997 at 400 North Main Street in the middle of the city's Historic District.

Porphyroblast
A porphyroblast is a large mineral crystal in a metamorphic rock which has grown within the finer grained groundmass.

Porphyroclast
autochthonous Western Gneiss Region and rocks of the allochthonous Blåhø nappe on Otrøy, Caledonides, Central Norway. A porphyroclast is a clast or mineral fragment in a metamorphic rock, surrounded by a groundmass of finer grained crystals.

Quartz
Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2.

Rock microstructure
Rock microstructure includes the texture of a rock and the small scale rock structures.

Schist
Schist (pronounced) is a medium-grade metamorphic rock with medium to large, flat, sheet-like grains in a preferred orientation (nearby grains are roughly parallel).

Shear (geology)
sinistral shear sense''', Starlight Pit, Fortnum Gold Mine, Western Australia Shear is the response of a rock to deformation usually by compressive stress and forms particular textures.

Western North Carolina
Western North Carolina (often abbreviated as WNC) is the region of North Carolina which includes the Appalachian Mountains, thus it is often known geographically as the state's Mountain Region.
