Aplite

Classification：Igneous Rock

Acid deep pluton, fine grained structure, usually light colored, mainly composed of quartz and feldspar. It is crystallized from remnant lava magma.

Aplite is an acid light color rock. It is a typical fine crystal structure. It contains almost no dark mineral. It is mainly composed of feldspar and quartz, so it is also known as feldspar, and its appearance is mostly sand sugar.

Fine grained granitic rocks. It is mainly composed of simple components such as quartz, plagioclase and sodium plagioclase, sometimes containing a small amount of muscovite, occasionally containing black mica, hornblende and trace tourmaline, garnet, fluorite and Huang Jing, which are characterized by poor volatile components and mineralizer. Uniform fine-grained, micro - granitic structure. Quartz and microcline sometimes like shape to report. Usually, they are small scale (several centimeters to tens of centimeters thick) dykes and dykes, which are intruded into granite bodies and are often associated with pegmatite. Some Aplite are shallow with the edge and top facies of granitic rock.

Classification:
Aplite is an acid light color rock. It is a typical fine crystal structure. It contains almost no dark minerals. As long as it is feldspar and quartz, it is also known as the feldspar, and its appearance is mostly sand sugar. It is probably crystallized from the remnant lava magma, according to it.

Mineral composition can be divided into:
Aplite diorite, grayish green, mainly composed of feldspar and amphibole;
Aplite long and light gray, mainly composed of feldspar and pyroxene.
Sodium Aplite long, gray white, gray red, almost all composed of albite.
Long Aplite, gray white, mainly composed of acidic plagioclase and quartz;
Granitic Aplite, pale white and shallow flesh red, mainly composed of acid plagioclase, quartz and albite.
