The Monoclinic System. The previously discussed crystal systems all have axes/sides that meet at 90 º. In the monoclinic system, two of the axes, A and C, meet at 90 º, but axis B does not. All axes in the monoclinic system are different lengths.
To be called a "pegmatite," a rock should be composed almost entirely of crystals that are at least one centimeter in diameter. The name "pegmatite" has nothing to do with the mineral composition of the rock. Most pegmatites have a composition that is similar to granite with abundant quartz, feldspar, and mica. These are sometimes called "granite pegmatites" to indicate their mineralogical composition.

Mineral Photos. Silicates—including quartz, mica, olivine, and precious minerals such as emeralds—are the most common class of minerals, as well as the major components of most rocks. Oxides, sulfides, sulfates, carbonates, and halides are other major mineral classes.
The mica group represents 37 phyllosilicate minerals that have a layered or platy texture. The commercially important micas are muscovite and phlogopite. Layering in the univalent (potassium, sodium), or true, micas imparts perfect basal cleavage, allowing crystals to be split into very thin sheets that are tough and flexible. Layering in the divalent, or brittle, micas also results in perfect basal .
