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.

The five basic substances involved in the rock cycle?
the five basic substances in the rock cycle are sediments magma igneous rock metamorphism
What type of rock is meta-conglomerate?
the meta conglomerate is a metamorphic rock it's mineral composition is from quartz & it has a non- foliated texture, it's formed via temprature (the agent of metamorphism) & the type of metamorphism is said to be "thermal" & the pre-metamorphic rock is conglomerate.
How is meta conglomerate different from conglomerate?
Conglomerate is a sedimentary rock that contains gravel-sized clasts. Metaconglomerate is conglomerate that has undergone metamorphism.
What is the name of the model that illustrates the origin of the three basic rock types?
The rock cycle.
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?
A conglomerate (sedimentary rock) is the protolith, or parent rock, of a metamorphic rock called a 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.
What is ultra basic rock?
A rock you can find in your garden.
