Physical Characteristics Of Granite Rocks

Granite is the most common intrusive rock in earth s continental crust it is familiar as a mottled pink white gray and black ornamental stone it is coarse to medium grained.

Physical characteristics of granite rocks.

Granite is coarse grained has a uniformly dispersed crystalline structure has a specific gravity of 2 6 2 7 is composed of varying amounts of various feldspars quartz micas and other. Granite is one of the most beautiful natural stone materials you can find. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral. After granite blocks are cut down into granite slabs the slabs are shipped off to fabricators.

However the petrographies are similar enough to make reasonable comparisons between them. Rocks are rated on the on the moh s hardness scale which rates the rocks on the scale from 1 to 10. In classifying igneous rocks significant 5 quartz is the defining characteristic. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar.

Learn more about the properties and uses of granite in this article. Its three main minerals are feldspar quartz and mica which occur as silvery muscovite or dark biotite or both. These characteristics of granite are established by its belonging to the group of igneous origin rocks formed by the crystallization of different materials coming from terrestrial magma which got cold deep inside and very slowly creating its granular texture. It forms from the slow crystallization of magma below earth s surface.

The physical properties of granite depend on its formation. Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock. Alaslcite granite of degelen dobretsov and mikhaylov 1985 as shown in figure 2. When they arrive at the fabrication facility they are shaped and finished according to the needs of your countertop.

Accounting for differences in porosity between our borehole samples and degelen rocks our measurements of physical properties. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Physical properties of rocks play an important role in determining its applications in various fields. Granite countertop characteristics.

Hardness and strength of granite. If it s not igneous it s not granite it contains quartz. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth.
