Syenite and Latite
Definition
Definition
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals

Formation
Formation
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Syenite and Latite Properties
Know all about Syenite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Syenite and Latite belong to Igneous Rocks.Texture of Syenite is Earthy whereas that of Latite is Aphanitic to Porphyritic. Syenite appears Banded and Foilated and Latite appears Rough. The luster of Syenite and Latite is subvitreous to dull. Syenite is available in brown, buff, cream, green, grey, pink, white colors whereas Latite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Syenite are cemetery markers, creating artwork and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
