Definition
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.
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks

Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

All about Ganister and Phyllite Properties
Know all about Ganister and Phyllite properties here. All properties of rocks are important as they define the type of rock and its application. Ganister belongs to Sedimentary Rocks while Phyllite belongs to Metamorphic Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Phyllite is Phyllitic Sheen, Slaty. Ganister appears Rough and Phyllite appears Crinkled or Wavy. The luster of Ganister is dull while that of Phyllite is phyllitic. Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Phyllite is available in black to grey, light greenish grey colors. The commercial uses of Ganister are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones and that of Phyllite are cemetery markers, commemorative tablets, creating artwork, writing slates.
