Minerals

The term rock is less specific, referring to any solid mass of mineral or mineral-like material. Common rocks are often made up of crystals of several kinds of minerals. There are some substances, like opal, which have the appearance of a mineral but lack any definite internal structure, are sometimes called mineraloids.

Hydrous Mineral

In addition to their dehydration behavior, the importance of these minerals will depend on their water content and modal abundance in the altered basalt. For example, lawsonite carries 11.3 wt.% water and is typically 7–15% of the altered crust while amphibole constitutes a larger fraction of the assemblage (20–60%) but contains only ∼2 wt.% water.

During contact metamorphism rocks are changed primarily by this?

Expert Answers: Metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting. The most abundant rocks in the crust are igneous, which are formed by the cooling of magma. Earth's crust is rich in igneous rocks such as granite and basalt.
