The sedimentary cyclicity reflects the cumulative impact of the sedimentation rate, geotectonic
movements, and eustatic oscillation: transgression at the beginning and regression at the end of the cycles.
Following an introduction reviewing igneous nomenclature, each chapter addresses a specific compositional category of magmatic rocks, covering definition, mineralogy, eruption/ emplacement processes, textures and crystallization processes, geotectonic
distribution, geochemistry, and aspects of magma genesis.
