Pegmatites may be composed of a variety of minerals. Terms such as granite pegmatite, gabbro pegmatite, syenite pegmatite, or names with any other plutonic rock type as prefix are used. Compositions in the range from granodiorite to granite are common.ome pegmatite bodies are small irregular patches less than 1 cm. (0.4 in) across in larger masses of plutonic or metamorphic rocks. Others may be thousands of meters in length and hundreds of meters thick. Some appear as dikes, veins, or sills. Many have irregular outlines.
The word igneous comes from the Latin for fire, and what igneous rocks have in common is that they formed by the cooling and crystallization of a melt. This material may have been lava erupted at the Earth's surface, or magma (unerupted lava) at depths of up to a few kilometers, or magma in deeper bodies (plutons).ranite is the light, coarse-grained rock formed at depth and exposed after deep erosion. It is rich in feldspar and quartz (silica) and hence is called a felsic rock. So granite is felsic and plutonic. Basalt and granite account for the great majority of igneous rocks.
