Syenite Basic Information

Syenite is a coarse-grained intrusive igneous rock of the same general composition as granite but with the quartz either absent or present in relatively small amounts.
Syenites are usually peralkaline and peraluminous, with high proportions of alkali elements and aluminium. The feldspar component of syenite is predominantly alkaline in character (usually orthoclase) . Plagioclase feldspars may be present in small quantities, less than 10%.
Syenites are formed from alkaline igneous activity, generally formed in thick continental crustal areas, or in Cordilleran subduction zones. To produce a syenite, it is necessary to melt a granitic or igneous protolith to a fairly low degree of partial melting. This is required because potassium is an incompatible element and tends to enter a melt first, whereas higher degrees of partial melting will liberate more calcium and sodium, which produce plagioclase, and hence a granite, adamellite or tonalite.

Syenite Application

The use of syenite under the sub-grain size: small grains may be polished or carved, as a decorative plate or works of art; medium-grained commonly used in the construction of piers, arch, dams, ports, Le foot, base, pavement etc.; grain thick rolled into rubble, is the fine aggregate concrete. As the syenite acid, also used as chemical, metallurgical production of acid lining and containers.
