Archaeological Significance
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.
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
