The ring on gneiss and schist surrounding the roughly circular Llano Uplift located in the eastern region of the Edwards Plateau, west of the Texas Hill Country in Central Texas is one exposure of metamorphic rocks. The Marathon Mountains northeast of Big Bend National Park are another area of exposed, folded metamorphosed rocks.
If you can find an open piece of dirt, you can find rocks. All rocks fallinto those three categories. If you find a flat, smooth piece of rock, you might have found slate, a metamorphic rock. However, most metamorphic rocks are hard to find in the New York area, as there are few plate tectonics in these parts. Anyhow, look for rocks and use this rock key: http://www.rockhounds.com/rockshop/rockkey/index.html
Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks. The rocks are under tons and tons of pressure, which fosters heat build up, and this causes them to change as rocks.
Rocks are constantly changing types. The three types are metamorphic, sedimentary and igneous. Igneous rocks are created when magma or lava cools and solidifies. Metamorphic rocks are created when rocks are put under high pressure and high heat, which compacts the molecules in the rocks. Sedimentary rocks are created when small particles of rocks accumulate in an area and are cemented together via pressure or chemical change. Therefore, sedimentary and igneous rocks can become metamorphic rocks if they are buried deep in the earth's crust. Metamorphic and sedimentary rocks can become igneous rocks if they are melted then resolidify from the magma or lava. Metamorphic and igneous rocks can become sedimentary rocks if they are chipped into tiny pieces then accumulate together and become cemented.
It could indicate that the area now exposed was subjected to erosion and uplift over a long expanse of time, thus exposing the metamorphic rock.
Most rocks with basaltic composition are found in volcanic regions, such as volcanic islands and mid-oceanic ridges. They are also commonly found in continental flood basalt provinces, which are large expanses of basaltic lava flows that cover extensive areas of land. Basaltic rocks can sometimes be found in other settings as well, such as in certain types of metamorphic rocks.

Intrusions of granite plutons change the surrounding rock through heat in a process known as contact metamorphism. Crustal collisions which may precipitate the melting of crustal material and its rise to the surface (and the creation of granite), also give rise to pressures and heat which can metamorphose other igneous, sedimentary, and metamorphic rocks in the surrounding area which is called regional metamorphism.
Interesting question, generally they can, in "layman" terms. Metamorphic rocks are rocks that undergo intense heat and pressure through either REGIONAL or CONTACT metamorphism. Regional - high pressure low temperature - environments eg within a mountain range. Contact - as it implies "contact" , hot magma comes in contact with surrounding rocks and is in an area of high temperature and low pressure eg; below volcanoes or around plutons (magma pockets or buldges in rocks )
Lightcrystals are found at in the rocks at the tundra area. They are more common in the white rocks though.
