Formation

Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
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.
