Granite is a type of igneous rock formed by the condensation of magma beneath the earth's surface. Its main components are feldspar and quartz. It is composed of potassium feldspar, quartz, plagioclase composed of acidic intrusive rocks, semi-self-shaped granular structure or like spot-like structure, block structure, often was rock, rock production. Related minerals are rare metals, radioactive mineral deposits. Applied granite materials science and technology (a subject), natural materials (two subjects), minerals (two subjects). The source of granite is the Latin granum, meaning grains or grains. Because granite is a deep pluton, often able to form a well-developed, macroscopical mineral particles, hence the name. Granite is not easy to weathering, beautiful colors, the appearance of color can be maintained for more than a century, due to its high hardness, wear resistance, in addition to high-level architectural decoration works, outside the hall, or open-air sculpture of choice.
The main component of granite
Granite is a deep acid-rich igneous rock formed by the condensation of magma in the deep underground. Part of granite is a gneiss or mixed rock that has been metamorphosed by magmatic and sedimentary rocks. The main mineral composition of granite feldspar, quartz, mica, etc., quartz content is 10% to 50%. Feldspar content of about 2/3 of the total, is divided into orthoclase, plagioclase (soda lime) and slightly plagioclase (potash). Different varieties of mineral composition vary, but also may contain pyroxene and hornblend.
Granite hard texture, hard to be acid-base or weathering erosion, often used in building materials. The source of Granite is Latin granum, while the Chinese name granite is translated from Japanese. The early Meiji Dictionary and Geology books translated Granite as granite or guaiazite. Flowers describe the rocks as beautiful, while Gang or Kong indicates that the rocks are hard, meaning hard-rock with flower-like markings. Chinese scholars follow this translation.
