They are sedimentary or igneous rocks that have undergone changes as a result of extreme pressure and heat. The name defines their formation whereby ‘meta’ means change and ‘morph’ means ‘form. Hence, metamorphic rocks are those whose forms have been changed through a geological process such as large tectonic movements and magma intrusions.
Igneous rocks are formed by the cooling and crystallization of a silicate melt (dominated by oxygen and silicon, with a variety of other metals). The occurrence and distribution of igneous rocks and igneous rocks types can be related to the operation of plate tectonics. The molten rock material from which igneous rocks form is called magma.

Hardness (h) the determination of the hardness of a mineral can be an important step nearly all of the rock-forming minerals are silicates, that is, they.
Based on your determination of the rocks texture and composition, identify the rock as either sedimentary, igneous, or metamorphic.
Organic sedimentary rocks are formed from the accumulation of any animal or plant debris such as shells and bones. These plant and animal debris have calcium minerals in them that pile on the seafloor over time to form organic sedimentary rocks. Examples include rocks such as coal, some limestone, and some dolomites.
This paper deals with a simplified procedure for classification of rock-forming chlorites based on chemical data obtained from electron microprobe analyses (empa). The proposed chlorite nomenclature does not include any new mineral name. The procedure gives the rules for determination of chlorite types (i and ii), and adjectival modifiers (mg-chlorite, fe-chlorite, al-chlorite). Riassuntoviene qui presentata una semplice procedura utile alla classificazione delle cloriti.
