Formation
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental 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 Granodiorite and Jasperoid Properties
Know all about Granodiorite and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Granodiorite belongs to Igneous Rocks while Jasperoid belongs to Sedimentary Rocks.Texture of Granodiorite is Granular, Phaneritic whereas that of Jasperoid is Earthy. Granodiorite appears Veined or Pebbled and Jasperoid appears Glassy or Pearly. The luster of Granodiorite is grainy, pearly and vitreous while that of Jasperoid is vitreous and pearly. Granodiorite is available in black, grey, orange, pink, white colors whereas Jasperoid is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Granodiorite 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).
