Archaeological Significance
Formation
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
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 Whiteschist and Jasperoid Properties
Know all about Whiteschist and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Whiteschist belongs to Metamorphic Rocks while Jasperoid belongs to Sedimentary Rocks.Texture of Whiteschist is Foliated whereas that of Jasperoid is Earthy. Whiteschist appears Banded and Foilated and Jasperoid appears Glassy or Pearly. The luster of Whiteschist is subvitreous to dull while that of Jasperoid is vitreous and pearly. Whiteschist is available in green, grey, white colors whereas Jasperoid is available in black, brown, green, grey, pink, white colors. The commercial uses of Whiteschist are creating artwork, gemstone, jewelry, production of lime 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).
