How many types of granite are there? How many types of granite are there

What are the types of granite, let's find out together.

The types of granite are hornblende granite, biotite granite, talc granite, electrical granite, black granite, muscovite granite, etc. The details are as follows:

1. Amphibole granite

Amphibole granite is a rock specimen collected in Beishan, Shujigou, Hongtoushan Town, Qingyuan Manchu Autonomous County, Fushun City, Liaoning Province. Grayish-white, porphyritic structure, massive structure, mainly hornblende 15%, potassium feldspar 40%, plagioclase 20%, quartz 25%. Amphibole granite is a dark granite variety that is suitable for all kinds of weather, so it is suitable for any use, most commonly as a building material.

2. Biotite granite

Biotite granite belongs to non-metallic ores, grayish-white, granite structure, massive structure. The main mineral composition is quartz, feldspar, biotite, amphibole. Biotite granite is a light fleshy red mass.

The rock is composed of potassium feldspar, plagioclase, quartz, biotite. Auxiliary minerals include magnetite, zelite, zircon, apatite, etc. The rock mass intruded into the Nanyuan Formation and developed kaolinization, which was a product of the early Yanshan Mountains, and had a strong gneiss-like structure due to extrusion.

Biotite granite exists in a variety of colors and is one of the most widely used granites for construction. It is the hardest of all granite and is suitable for both indoor and outdoor use.

3. Talc granite

Talc granite is one of the lesser-known forms of granite because it does not resist natural forces (wind, rain) very well. This makes it less suitable for use as flooring, countertops, and outdoors, and is only used for decorative purposes.

4. Electrical granite

Electric granite is a rock specimen collected in Japan. Grayish-white, semi-automorphic granular structure, massive structure, the main minerals are: quartz, potassium feldspar, acid plagioclase.

It is a high-quality building stone. Electrical granite comes in a variety of colors, except for colorless and white, which is extremely rare. This granite type is ideal for places without a lot of traffic, as it is soft for all types.

5. Black granite

Black granite is a natural stone that is resistant to dirt, acid, wear, compression, and insulation. In general, pure black granite from the Warrangal region has good color purity and hardness, and it looks gorgeous after polishing and can be preserved for a long time. Other sources such as Tamar Puli and Maitur in Tamil Nadu, Chetu and Kanman in Andrrapout, and Kanak Pura near Bengaluru are generally mid-to-mid-to-high-end.

6. Muscovite granite

Muscovite granite, mainly distributed in the area of Da Mo Peak and Shitu Ridge. The rock is grayish-white, fine-grained and equigranular semi-automorphic granular mosaic structure, occasionally porphyry, and the main rock-forming minerals that make up the rock are alkaline feldspar, plagioclase, quartz, leukite, and biotite. Mineral crystallization characteristics of muscovite granite:

Alkaline feldspar is mostly in other shape crystals, a few are semi-automorphic crystals, alkaline feldspar is mostly microcline feldspar with lattice double crystals, and alkaline feldspar and striped feldspar without lattice double crystals are also seen.

The above is the sharing, I hope it can help everyone.

1. The most common classification scheme is the geochemical and genetic alphabet classification scheme, such as dividing granite into S-type, I-type, M-type, A-type and C-type (S-type is granite transformed from sedimentary rock; Type I is of magmatic origin; M-type is mantle**; Type A is anhydrous granite; c for perilla granite tung chain); Or it can be divided into calc-alkaline, alkaline, peralkaline, peraluminium and aluminous granite, etc.

2. Or according to the tectonic background, it can be divided into "orogenic granite barrages" (oceanic and continental volcanic arcs; continental collision zones), "post-orogenic granite" (uplift or subsidence areas after the orogenic period), and non-"orogenic granite" (continental rifts, hot spots, mid-ocean ridges, oceanic islands), etc.

Granite is an igneous rock that is mainly composed of minerals such as quartz, feldspar, and mica. Due to its different composition and structure, granite can be divided into many different types, and here are some of the common granite species:

1.Bluestone: A black or dark grey splined limestone with granular white spots, commonly used for building facades and ground paving.

2.Quartz sandstone: A type of granite composed of quartz and sand grains, usually gray or pink in color, commonly used in construction and decorative materials.

3.Pearlite: A granite composed of calcareous minerals with a white or light gray color and a hard texture, commonly used in building materials, carvings, and ornaments.

4.Yellow jadeite: A yellow to green granite with a dense texture and high hardness, it is often used for architectural decoration, carving, and tombstones.

5.Black mica schist: A granite composed of biotite minerals, black or gray in color and hard in texture, commonly used in construction and decorative materials.

6.Red Sandstone: A red or brownish-red granite with a soft texture that is commonly used in construction and decorative materials.

In addition to the above few common granite species, there are many other types such as granulite, andesite, diabase, and many more. Each type of granite has its own unique characteristics and uses.

Granite is an igneous rock composed of minerals such as feldspar, quartz, and mica, which can be divided into the following types according to their composition and structure:1Granular granite:

It is composed of coarse-grained minerals such as feldspar, quartz, and mica, and the particles are large and show a distinct grain structure. 2.Porphyry granite:

It is composed of minerals such as feldspar and biotite, of which biotite exhibits a speckled distribution, hence the name porphyry granite. 3.Schist granite:

It is composed of minerals such as feldspar, quartz, and mica, of which mica exhibits a sheet-like structure, hence the name of the rock granite. 4.Red granite:

Composed of minerals such as feldspar, quartz, and plagioclase, it has a red or pink color, hence the name red granite. 5.Black Granite:

It is composed of minerals such as feldspar, quartz, and biotite, and exhibits a black or dark color, hence the name black granite and sacred rock.
