What kind of igneous rock is mafic and formed deep in the ground?
Gabbro is mafic and forms underground.
A metamorphic rock formed from coal?
Anthracite, a variety of coal, is formed from the metamorphosis of bituminous coal through natural processes of heat and pressure deep underground.
What type of volcano is yosemite granite domes?
They are not volcanoes. The Yosemite granite domes are plutons, formed from molten rock that cooled deep underground.
What type of rock can only form deeply underground?
Only an intrusive igneous rock forms underground, but you can argue that all metamorphism occurs underground. The issue here is that when the metamorphism is thermal, often the ground it is under has only just been formed (i.e. a lava flow). To avoid confusion, only regional metamorphism can take place underground. The rocks formed by regional metamorphism and intrusive magma cooling are rocks with crystalline texture.
Is Pumice formed deep underground?
No. Pumice forms from gas-rich lava that is ejected into the air.
What is formed when rock melts deep underground?
Magma
What rock is formed when rocks melt deep underground?
Magma
Are diamonds made deep underground in a rock?
A diamond is a metamorphic rock formed from carbon. Diamond formation requires intense heat and extreme pressure, which naturally occurs deep underground.
What type of rock can only form deep underground?
Metamorphic
What kind of igneous rock is mafic and formed deep in the ground?
Gabbro is mafic and forms underground.
Has Rio de Janeiro have any volcanos?
No. It does have igneous rock (granite) which was formed deep underground from magma, but this was never volcanic rock.
How does metamorphic rock formation compare to igneous rock formation?
Igneous rocks are formed in and around volcanos, metamorphic rocks are formed by the partial melting of rocks deep underground.
A metamorphic rock formed from coal?
Anthracite, a variety of coal, is formed from the metamorphosis of bituminous coal through natural processes of heat and pressure deep underground.
Is granite a sedimentary rocks formed underground?
No. Granite is an igenous rock that is formed underground.
How do silicate minerals form?
Most silicate minerals are formed when molten rock cools at either the earths surface, or deep underground.
What type of volcano is yosemite granite domes?
They are not volcanoes. The Yosemite granite domes are plutons, formed from molten rock that cooled deep underground.
What are the parent rocks of gabbro?
Gabbro is an igneous rock, and therefore does not have a parent rock as would a metamorphic rock. Gabbro is an intrusive igneous rock formed from the slow cooling and solidification of mafic magmas deep underground.
