Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
Granophyre is a type of granitic rock which consists of intergrown feldspar and quartz crystals in a medium to fine grained groundmass

Archaeological Significance
Formation
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.
Granophyre 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 Oolite and Granophyre Properties
Know all about Oolite and Granophyre properties here. All properties of rocks are important as they define the type of rock and its application. Oolite belongs to Sedimentary Rocks while Granophyre belongs to Igneous Rocks.Texture of Oolite is Clastic or Non-Clastic whereas that of Granophyre is Granophyric. Oolite appears Rounded and Rough and Granophyre appears Veined or Pebbled. The luster of Oolite is pearly to shiny while that of Granophyre is dull to grainy with sporadic parts pearly and vitreous. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas Granophyre is available in black, grey, orange, pink, white colors. The commercial uses of Oolite are creating artwork, jewelry, used in aquariums and that of Granophyre are curling, gemstone, laboratory bench tops, tombstones.
