Igneous and Metamorphic Petrology

Igneous and Metamorphic Petrology is the branch of geology that investigates the origin, composition, distribution, and structure of rocks formed from molten material (igneous) and those altered by heat and pressure (metamorphic). By studying igneous rocks like granite and basalt, scientists can understand processes such as volcanism and the cooling of magma within the Earth's crust and mantle. The analysis of metamorphic rocks, such as slate and marble, reveals the immense temperatures and pressures associated with tectonic processes like mountain building. Together, these studies provide a fundamental record of the dynamic thermal and tectonic history of the Earth's interior.
