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.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

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