Web25 okt. 2024 · Intermediate rocks have lower silica content (55-65%). They are darker than felsic rocks but lighter than mafic rocks. Some examples are: Andesite/dacite (extrusive) and diorite/granodiorite (intrusive). Is white granite mafic or felsic? Overall, granite is a felsic rock, with mafic minerals being secondary or accessory in nature. WebThe Solander and Little Solander rocks are incompatible element enriched (e.g. Sr ~931–2270 ppm, Ba ~619–798 ppm, Th ~8.7–21.4 ppm, La ~24.3–97.2 ppm) with MORB-like Sr and Nd isotopic signatures. Isotopically similar quench-textured enclaves reflect mixing with intermediate (basaltic-andesite) magmas.
