Formation

Formation
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.   
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 Syenite and Jasperoid Properties

Know all about Syenite and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Syenite belongs to Igneous Rocks while Jasperoid belongs to Sedimentary Rocks.Texture of Syenite is Earthy whereas that of Jasperoid is Earthy. Syenite appears Banded and Foilated and Jasperoid appears Glassy or Pearly. The luster of Syenite is subvitreous to dull while that of Jasperoid is vitreous and pearly. Syenite is available in brown, buff, cream, green, grey, pink, white colors whereas Jasperoid is available in black, brown, green, grey, pink, white colors. The commercial uses of Syenite are cemetery markers, creating artwork 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).
