Exempel på hur man kan använda METAMORPHIC i en mening

• It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks.
• Kyanite is a typically blue aluminosilicate mineral, found in aluminium-rich metamorphic pegmatites and sedimentary rock.
• Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock.
• Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock.
• Most of the islands have a bedrock formed from ancient metamorphic rocks, and the climate is mild and oceanic.
• Slate is a fine-grained, foliated, homogeneous, metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade, regional metamorphism.
• Soapstone (also known as steatite or soaprock) is a talc-schist, which is a type of metamorphic rock.
• It occurs as a common accessory mineral in igneous rocks (as primary crystallization products), in metamorphic rocks and as detrital grains in sedimentary rocks.
• 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.
• The pyroxenes (commonly abbreviated Px) are a group of important rock-forming inosilicate minerals found in many igneous and metamorphic rocks.
• Apatite is very common as an accessory mineral in igneous and metamorphic rocks, where it is the most common phosphate mineral.
• Layered textures or foliation in this metamorphic rock is typically around 30° to the east or northeast.
• North and west of this line are the older, generally harder rocks including igneous and metamorphic rocks and the Palaeozoic and Precambrian sandstones and limestones which usually stand out as upland areas.
• In other memoirs, among which may be mentioned those on the Cretaceous rocks of the Ardennes and of the Basin of Oviedo, Spain; on the (Devonian) Calcaire d’Erbray; on the Palaeozoic rocks of Brittany and of northern Spain; and on the granitic and metamorphic rocks of Brittany, Dr Barrois proved himself an accomplished petrologist as well as palaeontologist and field-geologist.
• Actinolite is commonly found in metamorphic rocks, such as contact aureoles surrounding cooled intrusive igneous rocks.
• The coticule is a metamorphic microcristalin schist, very fine grained, 35 to 40% of it small crystals of spessartine, of about 5 to 20 μm in diameter.
• It also occurs in metamorphic rocks of granulite facies, in metamorphosed carbonate rocks, and corundum deposits.
• They are mostly composed of high-grade metamorphic rocks, amphibolite to granulite gneiss, that are intruded by anorthosite, mangerite, charnockite, and granite plutonic rocks.
• Mount Dana is composed of prebatholithic rock that is mostly reddish metamorphic rock, which was composed by metavolcanics of surfacing magma from the Mesozoic Era.
• chatoyant gemstone that is usually a metamorphic rock with a golden to red-brown colour and a silky lustre.
