Exempel på hur man kan använda IGNEOUS i en mening

• It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms.
• The national park’s distinctive hard black boulders (often termed granite) and range are composed of the igneous felsic intrusive Trevethan Granodiorite which is predominantly a white to grey, medium-grained, porphyritic biotite monzogranite to granodiorite.
• It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks.
• Most geologists accept the theory that the older rocks at the center of the uplift are a result of this deep-seated igneous activity.
• Porphyry (geology), an igneous rock with large crystals in a fine-grained matrix, often purple, and prestigious Roman sculpture material.
• Two vertical diabase dikes, made up of highly impermeable igneous basalt parent rock, cut through the limestone bedrock in the area and form a subterranean "V", with Boiling Springs located at the interior tip of the V.
• Syenite is a coarse-grained intrusive igneous rock with a general composition similar to that of granite, but deficient in quartz, which, if present at all, occurs in relatively small concentrations (< 5%).
• Glaciation has left the area with only a thin layer of soil, through which exposures of igneous bedrock resulting from its long volcanic history are frequently visible.
• Apatite is very common as an accessory mineral in igneous and metamorphic rocks, where it is the most common phosphate mineral.
• Covering most of the island, the coastal sedimentary plateau is a succession of highly eroded sedimentary peaks which are part of the Franklinian Shield with an extension of the Canadian Shield (Precambrian igneous and metamorphic rocks) in the island's southeastern corner.
• Orthoclase is a common constituent of most granites and other felsic igneous rocks and often forms huge crystals and masses in pegmatite.
• It occurs as a common accessory mineral in igneous rocks (as primary crystallization products), in metamorphic rocks and as detrital grains in sedimentary rocks.
• In geology, felsic is a modifier describing igneous rocks that are relatively rich in elements that form feldspar and quartz.
• Cryptocrystalline tool stones include flint and chert, which are fine-grained sedimentary materials; rhyolite and felsite, which are igneous flowstones; and obsidian, a form of natural glass created by igneous processes.
• Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock.
• The boulders range in size from three pounds to an estimated 25 tons and are igneous plutonic or intrusion rocks, which are formed by molten magma that solidifies underground before it reaches the surface of the earth.
• A pleochroic halo, or radiohalo, is a microscopic, spherical shell of discolouration (pleochroism) within minerals such as biotite that occurs in granite and other igneous rocks.
• The bedrock of Harris is largely Lewisian gneisses, which were laid down in the Precambrian period, interspersed with igneous intrusions.
• The islands constitute one of the two exposed parts of the Kerguelen Plateau (the other being Heard Island and the McDonald islands), a large igneous province mostly submerged in the southern Indian Ocean.
• The pyroxenes (commonly abbreviated Px) are a group of important rock-forming inosilicate minerals found in many igneous and metamorphic rocks.
