Formation

Formation
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.  
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
