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.

Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.
