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.
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Etymology
From gan′is-ter i.e a hard, close-grained siliceous stone, often forming the stratum which underlies a coal-seam
From oo- + -lite, after German Oolit. A rock consisting of fine grains of carbonate of lime

Archaeological Significance
Formation
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

All about Ganister and Oolite Properties
Know all about Ganister and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Ganister and Oolite belong to Sedimentary Rocks.Texture of Ganister is Clastic, Granular, Rough whereas that of Oolite is Clastic or Non-Clastic. Ganister appears Rough and Oolite appears Rounded and Rough. The luster of Ganister is dull while that of Oolite is pearly to shiny. Ganister is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow 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 Oolite are creating artwork, jewelry, used in aquariums.
