5 Formation

5.1 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.

Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
