A metabasic rock is an igneous rock formed at deeper than crustal conditions. They are often metastable and alter to more traditional crustal rocks as they are exhumed.
Metabasics are important because they contain the only record we have of Mantle chemistry, and some may be subducted ancient oceanic crust which worked it's way back to the surface.

What type of rock is meta-conglomerate?
Meta-conglomerate is a metamorphic rock that forms from the metamorphism of conglomerate, which is a sedimentary rock composed of rounded gravel and pebbles. The process of metamorphism changes the texture and mineral composition of the conglomerate, resulting in meta-conglomerate.
The five basic substances involved in the rock cycle?
The five basic substances involved in the rock cycle are magma, igneous rock, sedimentary rock, metamorphic rock, and mineral crystals. These substances undergo processes such as melting, cooling, weathering, and metamorphism to transition between different rock types in the cycle.
How is meta conglomerate different from conglomerate?
Conglomerate is a sedimentary rock that contains gravel-sized clasts. Metaconglomerate is conglomerate that has undergone metamorphism.
One of the eight basic rock forming minerals?
Quartz is one of the eight basic rock-forming minerals, also known as the "Rock-Forming Minerals of the Earth's Crust." It is abundant in igneous, sedimentary, and metamorphic rocks, contributing to the structure and composition of many rock types. Along with quartz, other common rock-forming minerals include feldspar, mica, amphibole, pyroxene, olivine, calcite, and garnet.
What is the name of the model that illustrates the origin of the three basic rock types?
The model that illustrates the origin of the three basic rock types is called the rock cycle. It shows how igneous, sedimentary, and metamorphic rocks are interrelated through processes like melting, cooling, weathering, and metamorphism.
What particles are an asteroid made of?
Meta, rock, and/or water
Why does aniline when subjected to nitration conditions followed by a basic work up form the meta nitroanline and not ortho or para?
It reacts with the acidic conditions (since the NH2 is basic) to form the meta-directing electron withdrawing group NH3. This forms the meta-nitroaniline.
What is the protolith of meta conglomerate?
The protolith of metaconglomerate is a sedimentary rock called conglomerate. Conglomerate is composed of rounded gravel-sized clasts that are cemented together. Through the process of metamorphism, this sedimentary rock undergoes changes in temperature and pressure to form metaconglomerate.
The word elements meta and morph are Latin for?
hidden and rock
Is metaconglomerate an igneous rock?
No, metaconglomerate is a metamorphic rock, hence the "meta-" addition in front of the usually sedimentary rock conglomerate.
Is a meta conglomerate a metamorphic igneous or a sedimentary?
It is a metamorphic rock formed from a progenitor sedimentary rock called a "conglomerate".
Which two rocks could be cut into building blocks to make walls of buildings?
Igneous rock and Meta-igneous rock.
Type of rockformed from sediments called?
A rock formed for sedimentary deposits is called a sedimentary rock. A sedimentary rock which has then undergone metamorphism is called a meta-sediment.
What process has to accure for a rock to become metamorphic rock?
Metamorphic rock "meta-morphs," or changes, from other rock forms, typically sedimentary, through a combination of heat, pressure, and of course time.
What grain structure does gneiss have?
Gneiss which is a non-foliated meta-igneous rock is coarse grained in texture.
One of the eight basic rock forming minerals?
Quartz is one of the eight basic rock-forming minerals, also known as the "Rock-Forming Minerals of the Earth's Crust." It is abundant in igneous, sedimentary, and metamorphic rocks, contributing to the structure and composition of many rock types. Along with quartz, other common rock-forming minerals include feldspar, mica, amphibole, pyroxene, olivine, calcite, and garnet.
What is ultra basic rock?
Ultra basic rock is a type of igneous rock that has a low silica content and high levels of magnesium and iron. It typically forms from the partial melting of the Earth's mantle, and examples include basalt and gabbro. Ultra basic rocks are characterized by their dark color and fine-grained texture.
