Syenite Basics

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 (<5%).

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.
