Definition of igneous in English English dictionary
Resulting from, or produced by, the action of great heat; with rocks, it could also mean formed from lava/magma; as, granite and basalt are igneous rocks
Pertaining to, having the nature of fire; containing fire; resembling fire; as, an igneous appearance
produced under conditions involving intense heat; "igneous rock is rock formed by solidification from a molten state; especially from molten magma"; "igneous fusion is fusion by heat alone"; "pyrogenic strata"
1 From a magma; said of a rock or mineral that solidified from molten or partly molten material 2 A rock or mineral that solidified from molten or partly molten material
Any rock solidified from molten or partly molten material BWCA basalt, gabbro, and granite are of igneous origin
adj a word used to describe any type of rock that was once molten, whether as magma (inside the earth or intrusive) or lava (outside the earth or extrusive); one of three major rock types; see also sedimentary and metamorphic
Said of a rock or mineral that solidified from molten or partly molten material, i e from magma; also, applied to processes leading to, related to, or resulting from the formation of such rocks Igneous rocks constitute one of the tree main classes into which rocks are divided, the others being metamorphic and sedimentary
Resulting from, or produced by, the action of fire; as, lavas and basalt are igneous rocks
Pertaining to, having the nature of, fire; containing fire; resembling fire; as, an igneous appearance
Rock formed by cooled and hardened magma within the crust or lava on the surface
One of the three basic categories into which rocks can be classified, of which the other two are sedimentary and metamorphic Igneous rocks are formed by the cooling of molten rock, called magma
(1) A type of rock formed from a molten, or partially molten, material (2) An activity related to the formation and movement of molten rock either in the subsurface (plutonic) or on the surface (volcanic)
A rock which has formed by cooling from the molten Igneous rocks include lavas and other products of volcanoes (eg ash) as well as rocks which crystallise at great depth in the crust, such as granites or gabbros
rocks that crystallize below the Earth's surface are called intrusive - they have large crystals produced by slow cooling Granite is an example of an intrusive rock; basalt is an example of an extrusive rock
One of the three types of rocks Igneous rocks are made when magma cools off and can either be made above or under ground More info -
A type of rock that is formed when magma cools Igneous rocks can be either of volcanic or plutonic origin
In geology, igneous rocks are rocks that were once so hot that they were liquid. igneous rocks are formed from lava (=hot liquid rock) (igneus, from ignis; IGNITE)
A type of rock that is formed by the cooling of melted rock material either within or on the surface of the Earth
one of the major groups of rock that makes up the crust of the Earth; formed by the cooling of molten rock, either below the surface (intrusive) or on the surface (extrusive)
Any of various crystalline or glassy, noncrystalline rocks formed by the cooling and solidification of molten earth material (magma). Igneous rocks comprise one of the three principal classes of rocks, the others being metamorphic and sedimentary rocks. Though they vary widely in composition, most igneous rocks consist of quartz, feldspars, pyroxenes, amphiboles, micas, olivines, nepheline, leucite, and apatite. They may be classified as intrusive or extrusive rocks
