5 Formation

5.1 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.

All about Boninite and Jasperoid Properties

Know all about Boninite and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Jasperoid belongs to Sedimentary Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Jasperoid is Earthy. Boninite appears Dull and Soft and Jasperoid appears Glassy or Pearly. The luster of Boninite is vitreous while that of Jasperoid is vitreous and pearly.
