Igneous Petrology by C. J. Hughes is a comprehensive upper-level geology text focused on the origin, evolution, and classification of igneous rocks, integrating classical petrology with modern geochemical and tectonic concepts.

Key topics include:

• Physical properties and chemistry of magmas

• Crystallization processes and phase equilibria

• Fractional crystallization, assimilation, and magma differentiation

• Igneous rock series and tectonic settings

• Oceanic vs. continental igneous provinces

• Extensive tables, diagrams, and references (750+ citations)

This volume is especially valued by geology students, researchers, and professionals in petrology, volcanology, and geochemistry.
