Metamorphic Rocks: Types, Characteristics, and Examples

The metamorphic rocks are of two types: foliated and non-foliated metamorphic rocks. Most of the metamorphic rocks are made of layers that can easily be split apart. Marble is the only metamorphic rock, which contains veins & is durable, and can be easily dissolved by lemon juice or other acids.

Reading: Characteristics of Metamorphic Rocks | Geology

The type of rock that a metamorphic rock used to be, prior to metamorphism, is called the protolith. During metamorphism the mineral content and texture of the protolith are changed due to changes in the physical and chemical environment of the rock. Metamorphism can be caused by burial, tectonic stress, heating by magma, or alteration by fluids.

Common Metamorphic Rocks: Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble. Foliated Metamorphic Rocks: Some kinds of metamorphic rocks -- granite gneiss and biotite schist are two examples -- are strongly banded or foliated. (Foliated means the parallel arrangement of certain mineral grains that gives the rock a ...

These rocks are poorly coherent, laminated and fissile but, nevertheless, when the clay component is predominant, can be used to produce bricks, tiles, and earthenware in general. Other rocks unsuitable for use are very schistose metamorphic rocks (phyllites) and volcanites rich in a glass component (obsidian, pumice).
