Igneous rock (igneous from Latin igneus 'fiery'), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic.Igneous rocks are formed through the cooling and solidification of magma or lava.
Magmatism is the emplacement of magma within and at the surface of the outer layers of a terrestrial planet, which solidifies as igneous rocks.It does so through magmatic activity or igneous activity, the production, intrusion and extrusion of magma or lava.
El Opeño is a Mesoamerican archaeological site located in the municipality of Jacona in the state of Michoacán, Mexico.It is home to a prehispanic site, mainly known from the ceramic material found in the funerary complexes of the site, which have been dated to the Late Preclassic period.
Geology is the study of Earth and its components, including the study of rock formations. Petrology is the study of the character and origin of rocks.
Peridotite, a type of ultramafic rock. Ultramafic rocks (also referred to as ultrabasic rocks, although the terms are not wholly equivalent) are igneous and meta-igneous rocks with a very low silica content (less than 45%), generally >18% MgO, high FeO, low potassium, and are usually composed of greater than 90% mafic minerals (dark colored, high magnesium and iron content).
Basalt. A mafic mineral or rock is a silicate mineral or igneous rock rich in magnesium and iron.Most mafic minerals are dark in color, and common rock-forming mafic minerals include olivine, pyroxene, amphibole, and biotite.
Metamorphic rocks form one of the three great divisions of rock types. They are distinguished from igneous rocks, which form from molten magma, and sedimentary rocks, which form from sediments eroded from existing rock or precipitated chemically from bodies of water.
Ignimbrite, a volcanic rock deposited by pyroclastic flows. Volcanic rocks (often shortened to volcanics in scientific contexts) are rocks formed from lava erupted from a volcano.
