What else can I help you with?
A classification scheme that grouped plutonic and metamorphic rocks together and sedimentary and volcanic rocks together would be based on what?
This classification scheme would likely be based on the genesis or origin of the rocks, as plutonic and metamorphic rocks are both associated with processes occurring beneath the Earth's surface (igneous intrusion and metamorphism), while sedimentary and volcanic rocks form at or near the Earth's surface through sedimentation and volcanic activity, respectively.
Is grandodiorite a plutonic or volcanic?
Granodiorite is a type of plutonic rock, meaning it forms from the slow cooling of magma beneath the Earth's surface. It is composed mainly of plagioclase feldspar and quartz, with smaller amounts of biotite, hornblende, and other minerals.
What clue tells geologists intrusion?
A clue that tells geologists about an intrusion is the relationship between the rock layers. An intrusion is younger than the surrounding rocks it cuts through, so if the intrusion appears to cut across existing layers, it is likely an intrusion. Additionally, the mineral composition and texture of the intrusion can differ from the surrounding rocks, providing further evidence of an intrusion.
What is the meaning of a plutonic earthquake?
A plutonic earthquake is a seismic event caused by the movement of magma deep within the Earth's crust. These earthquakes typically occur beneath volcanic regions or in areas where there is active magmatic activity. They are often associated with the formation of intrusive igneous rock formations.
What are the key differences between volcanic and plutonic rocks in terms of their formation and characteristics?
Volcanic rocks form from lava that cools quickly on the Earth's surface, while plutonic rocks form from magma that cools slowly beneath the surface. Volcanic rocks have fine-grained textures, while plutonic rocks have coarse-grained textures. Volcanic rocks are often found in volcanic regions, while plutonic rocks are typically found deeper underground.
What kind of rock is a small dome like plutonic intrusion that forms rounded hills on earth surface?
A laccolith.
Why is copper found in specific places?
Because geological processes have concentrated it in these places. (Usually those processes related to intrusion and cooling of plutonic magma bodies.)
What is a plutonic dome?
A plutonic dome is found in areas of flat-lying sedimentary rocks that sloped up to create a roughly circular shape. Its core is made up of plutonic or igneous rocks that arched up the overlying sedimentary layers.
If an area is covered in igneous rock what can you tell about that areas past?
The area would have had; a) a plutonic intrusion underneath the surface rock, and the surface rock had eroded away, or b) previous volcanic eruption(s).
Is andesite plutonic?
No. It is volcanic. The plutonic equivalent of andesite is diorite.
What is classifies into?
Cooled magma is turned into a plutonic igneous rock, eg. Granite (you can see the difference between plutonic and volcanic because plutonic have large crystal particles)
Do old rocks form new rocks?
Rocks that are weathered and eroded can have their particles transported to a place of deposition and become new sedimentary rock. Rocks can become molten, then solidify, becoming new igneous rocks. Rocks can be metamorphosed by: a) exposure to heat by close proximity to a heat source such as a plutonic intrusion; b) from deep burial pressures; c) direct pressure and heat from mountain building processes; d) chemical changes from exposure to heated fluids, the fluids heated by a plutonic intrusion. Metamorphism of rocks can result in a realignment of mineral constituents, recrystallization, or new chemical compositions.
What are the names of a plutonic solid?
Solid plutonic rocks are intrusive igneous rocks such as granite and gabbro.
What cooledmagma is classified into?
Cooled magma is turned into a plutonic igneous rock, eg. Granite (you can see the difference between plutonic and volcanic because plutonic have large crystal particles)
Why is there no antonym for abyss?
The word abyss is a noun, referring to a deep chasm. In geology a plutonic intrusion known as a "dike" could possibly serve as an antonym for abyss, though that would require subsequent erosion of surrounding material, which isn't necessarily part of the definition.
Is granite plutonic or volcanic?
Granite is a plutonic rock, meaning it forms from the slow cooling and crystallization of magma underground. It is composed mainly of quartz, feldspar, and mica minerals.
Is plutonic intrusive?
Yes it is
