Chemical classification of common volcanic rocks based on degree of silica saturation and CaO/K2O ratio
Abstract Modal classifications of common volcanic rocks are expensive, difficult, or impossible to attain. As a consequence, these rocks are classified using the chemical composition. However, existing classificatory diagrams are unable to identify all 16 families of common volcanic rocks; the most...
