Nepheline Syenite and Ganister

1 Definition
1.1 Definition
Nepheline Syenite is a holocrystalline plutonic rock resembling syenite but containing nepheline and lacking quartz
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.

From origin of a Palaeozoic nepheline syenite from northern Shanxi Province, China
From gan′is-ter i.e a hard, close-grained siliceous stone, often forming the stratum which underlies a coal-seam

5 Formation
5.1 Formation
Nepheline Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
