This melted rock is called magma when it is inside the earth. Quartz and feldspar minerals can be found in all three types of rock, although they are most abundant in igneous rocks since this is where the minerals first form. Because this cooling process is slow, visible (or, phaneritic) mineral grains have time to form and are usually visible with the naked eye. Grains consist of several interlocking crystals (or sub-crystals), each having straight or undulating (strained) extinction. Muscovite mica Muscovite in economic quantities is confined to coarse-grained granite pegmatite dykes consisting largely of quartz, feldspar and mica. Quartz (SiO2) is present in almost all rocks. Pegmatite is an igneous rock that form end of the stage a magma's crystallization. It is a type of phyllosilicate, exhibiting a two-dimensional sheet or layer structure. Pegmatites contain exceptionally large crystals and they contain rarely minerals than other types of rocks. The resultant type of igneous rock texture is called:, When lava erupts and cools, if may form a ground mass of small crystals occurring together with larger phenocrysts that grew in the magma while it was still inside the Earth.

Cooling rate that is fine Grained (Lava cools more quickly because it on the surface) Slow Cooling. It was once customary to express the chemical composition of a mineral as an oxide formula (mostly because the structural relationships between the elements involved were not precisely known), and it is still useful if one reflects the silica content. It forms from the slow crystallization of magma below Earth's surface. Mica noun. quartz, and biotite mica.~ Common mineral types include quartz, feldspar and biotite and are often found in a glassy matrix. Quartz is a constituent of many rocks, eg. Quartz is found in igneous, sedimentary and metamorphic rocks. The higher percentage of K in these granites results in the mica being muscovite as well as, or instead of, biotite. Rocks and minerals must be examined in person from all perspectives for accurate identification; they are extremely difficult to identify through photographs. Dark fine-grained sedimentary rock composed of layers of compressed clay mud or silt.
