Volcanics and volcanisedimentary rocks

      The volcanics (extrusive or effusive magmatic rocks) resulted from volcanic action on or near the Earth´s surface, either as lava flows or as volcanic explosion (volcanic ash, lapilli, bombs). The products can be retransported to considerable distance. Volcanisedimentary rocks consist of a mixture of volcanic products and sediments. These two compouds can be mixed or deposited in alternating layers. Tuffite is a good example.
