Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
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.
