Origin of Igneous Rocks

The video tutorial explores the formation and classification of rocks, focusing on igneous rocks. It explains how minerals and rocks form due to environmental factors like pressure and temperature. The process of decompression melting and flux melting is detailed, highlighting their roles in volcanism. The crystallization sequence of minerals in cooling magma is discussed, using Bowen's reaction series as a model. The concept of differentiation is introduced, explaining how magma composition changes as it cools, with examples from Hawaii and Yellowstone.
