Orthoclase is potassium-rich, aiding in granite formation, while plagioclase contains calcium or sodium, key in basalt.
Basalt is a dark-colored, fine-grained,igneous rockcomposed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It has a composition similar to...

toward the surface and erupts through cracks or vents. The molten rock released during an eruption is referred to as lava, which rapidly cools and crystallizes to form igneous rocks. Lava rocks are a type of igneous rock known as basalt, which is composed of various mineral and chemical ...
The lithosphere is composed of the upper mantle and the crust and it is the outermost shell of a terrestrial planet or natural satellite. The study of the solid features on the Earth, the composition of rocks and the processes which can cause change are studied in geology. Rocks and unlithi...
Sand, too, is mostly grains of silicates weathered out of rock: from the endless sand of the Sahara to the garnet sands of upstate New York's Ausable River to the jet-black beaches of Iceland, where the sand is finely polished grains of basalt and volcanic glass. Your average fleck of ...
basaltSUMAThe composition of the upper mantle bounded by the Canaries, Eastern Anatolia, Libya and Poland is indirectly investigated by means of the chemical composition of igneous rocks with 'anorogenic' geochemical characteristics emplaced during the Cenozoic. The relatively homogeneous composition of ...
In creative arts, the form is the medium and technique used by the artist, while the structure is the underlying framework or composition of the artwork. In music, form can refer to the genre or style of a piece, whereas structure pertains to the arrangement of musical elements like rhythm...
