The Differences Between Sedimentary, Igneous, and Metamorphic Rocks…
Igneous Rocks: Provide valuable minerals and metals, such as granite for construction. Metamorphic Rocks: Used in building materials (marble, slate) and as indicators of geological processes.

Types of Rocks – Igneous, Sedimentary, Metamorphic
Igneous, sedimentary, and metamorphic rocks are the three types of rocks. Rocks fall into one of these categories depending on how they form and are then further subcategorized according to formation, composition, and other properties.

Types of Rocks
Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat with temperatures greater than 150 to 200°C and pressure around 1500 bars, causing profound physical and/or chemical change. Following are the two types of metamorphic rock:

Metamorphic Rocks – Introduction to Earth Science
6.4 Metamorphic Environments. As with igneous processes, metamorphic rocks form at different zones of pressure (depth) and temperature as shown on the pressure-temperature (P-T) diagram. The term facies is an objective description of a rock. In metamorphic rocks facies are groups of minerals called mineral assemblages. The names of metamorphic facies on the pressure …

Igneous Rocks | Types, Classification, Properties, Formation
Igneous rocks are one of the three main types of rocks found on Earth, the other two being sedimentary and metamorphic rocks. These rocks form from the solidification and cooling of molten material, known as magma, which originates deep within the Earth's crust and occasionally even in the mantle. The term "igneous" comes from the Latin word "ignis," …
