Archaeological Significance
Formation
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.
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 Diamictite and Jasperoid Properties
Know all about Diamictite and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Diamictite and Jasperoid belong to Sedimentary Rocks.Texture of Diamictite is Clastic whereas that of Jasperoid is Earthy. Diamictite appears Banded and Jasperoid appears Glassy or Pearly. The luster of Diamictite is grainy, pearly and vitreous while that of Jasperoid is vitreous and pearly. Diamictite is available in brown, buff colors whereas Jasperoid is available in black, brown, green, grey, pink, white colors. The commercial uses of Diamictite are commemorative tablets, creating artwork, 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).
