Exempel på hur du använder PLUTON i en mening

• They all are a result of the folding of the earth layers through the Mesozoic, causing also magma sheet-like intrusion (or concordant pluton) that has been injected between layers of sedimentary rock.
• The rock spires in the City of Rocks and adjacent Castle Rocks State Park are largely composed of granitic rock of the Oligocene Almo pluton and Archean Green Creek Complex.
• These rocks intruded from Triassic to Cretaceous time in southern Maine, New Hampshire, and Vermont with the relatively young Ascutney pluton intruding at ~122 MA (K/Ar date on biotite).
• An igneous intrusion that has intruded and obscured the contact of a terrane with adjacent rock is called a stitching pluton.
• The Cheviot was formed when melting in the crust over 390 million years ago gave rise to volcanic activity, producing a stratovolcano and pluton, and it has subsequently sustained intense erosion.
• Monzonite is found in association with gabbro and granodiorite in the Khankandi pluton in the Alborz Mountains of Iran.
• The Chief is part of a medium-sized pluton of a granitic rock (granodiorite) that was initially formed in the early Cretaceous (approximately 100 million years ago) by the slow cooling and solidification of molten magma deep below the surface of the Earth.
• At Hatcher Pass a pervasively altered zoned 74 Ma (million years old) quartz diorite to tonalite pluton underlies the headwaters of Willow Creek and Fishhook Creek; most of the gold deposits occur in these rocks.
• A phacolith is a pluton of igneous rock parallel to the bedding plane or foliation of folded country rock.
• This pluton emplaced at 304 ± 1 Ma (U-Pb dating on zircons), along a thrust surface separating a pile of allochthonous tectonic units from the Foreland.
• Around the eastern, southern and western edges of this pluton is a complex association of Pennsylvanian-era argillite, greywacke, chert and diabase.
• It also occurs in blocks of pegmatite as rock-forming grains in a moraine of the Dara Pioz glacier in northern Tajikistan; in the Del Salto pluton in Aysén Province, Chile; as euhedral crystals at Virikkollen, Haneholmveien, Sandefjord, Norway; Ampasibitika, Ampasindava Peninsula, Madagascar; and as gemmy crystals up to 3 cm from Mt.
• Ore bodies are in metamorphosed steeply dipping Precambrian pelitic and calcareous rocks of a roof pendant adjacent to a Cretaceous porphyritic quartz monzonite pluton.
• The Talkeetna Mountains batholith in this area consists of a pervasively altered zoned 74 Ma (million years old) tonalite body underlying Hatcher Pass and the headwaters of Willow Creek, and a 67 Ma quartz monzonite pluton farther west.
