Chemical classification of granite
WebAnswer: Igneous rocks can be divided into four categories based on their chemical composition: felsic, intermediate, mafic, and ultramafic. The diagram of Bowen’s reaction series (Figure 7.6) shows that differences in chemical composition correspond to differences in the types of minerals within an igneous rock. WebApr 12, 2024 · These may be named formally or informally as a class of intrusive rock or within a larger igneous association. While difficult to be certain of derivation of pegmatite in the strictest sense, often pegmatites are referred to as “metamorphic”, “granitic” or “metasomatic”, based on the interpretations of the investigating geologist.
