What type of ultramafic rock sometimes contains diamond?
Kimberlites are the rock type that diamonds are usually found in. They are formed when a magma from deep in the mantle drills its way to the surface in a fast gaseous explosive event. Diamonds typically occur as xenocrysts within the Kimberlite matrix. the volcanic deposits are called Lamproite igneous volcanic pipes. Please see the related links.
A certain igneous rock contains about 25 percent dark silicate minerals The remainder of the rock is mostly plagioclase feldspar What type of composition does tthis igneous rock have?
ultramafic
Which type of ultrabasic rock sometimes contains diamonds?
Kimberlite is a type of ultrabasic rock that sometimes contains diamonds. These rocks are formed deep within the Earth's mantle and are brought to the surface through volcanic activity, carrying diamonds with them.
What igneous rock contains mostly pyroxene and olivine?
Ultramafic igneous rocks are comprised mostly of olivine and pyroxene. Examples include peridotite (pegmatic and porphyritic) and komatite.
What type of rock contains lava or magma?
The type of rock that contains lava or magma is an igneous rock.
What type of rock is formed not by plate tectonics?
diamonds
Which igneous rock out of granite basalt andesite and peridotite has the lowest silica SiO2 content?
Peridotite, a type of ultramafic rock composed largely of the mineral olivine, has the least silica.
Is dunite an intrusive or extrusive igneous rock?
Dunite is an intrusive igneous rock, specifically a type of ultramafic rock composed mostly of olivine. It forms deep within the Earth's crust through the crystallization of magma.
What types of rock is in the mantle?
the mantle is made up of solid hot rock.
What type of rock is peridotite?
Peridotite is a type of ultramafic rock that is primarily composed of the minerals olivine and pyroxene. It is typically found in the mantle of the Earth and is associated with igneous processes such as the formation of oceanic crust at mid-ocean ridges.
What type of rock is the only rock that contains fossils?
sedimentary
What is Earth's mantle made from?
It is made from a rock type known as Peridotite.Peridotite is an ultramafic dense, coarse-grained igneous rock consisting mostly of the minerals olivine and pyroxene containing less than 45% silica.
