Definition
Granophyre is a type of granitic rock which consists of intergrown feldspar and quartz crystals in a medium to fine grained groundmass
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

Archaeological Significance
Formation
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.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

All about Granophyre and Dolomite Properties
Know all about Granophyre and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Granophyre belongs to Igneous Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Granophyre is Granophyric whereas that of Dolomite is Earthy. Granophyre appears Veined or Pebbled and Dolomite appears Glassy or Pearly. The luster of Granophyre is dull to grainy with sporadic parts pearly and vitreous while that of Dolomite is vitreous and pearly. Granophyre is available in black, grey, orange, pink, white colors whereas Dolomite is available in black, brown, green, grey, pink, white colors. The commercial uses of Granophyre are curling, gemstone, laboratory bench tops, tombstones and that of Dolomite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
