The rhyolite is composed of potassium feldspar and quartz, and the crystal shape is square plate, with glass luster, but cleavage. Is a gray, pink or brick red rock with a plaque structure and a stripe structure.
Basalt is the main component of sodium aluminosilicate or calcium aluminosilicate, silica content of 45% to 52%, also contains high iron oxide and magnesium oxide, is a dense dense black rock.
Basalts and rhyolites are igneous rocks that are ejected from volcanoes or spilled from the surface fissures.
