Archaeological Significance
Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
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.
