It is also useful for studying minerals such as cordierite, which can be difficult to distinguish.In minerals from the Peña Negra anatectic complex, Spain, the image density decreases in the order tourmaline ≫ sillimanite ≈ muscovite ≈ sericite > chlorite > cordierite > biotite > feldspar ≈ quartz. The sillimanite image comes mostly from B, the cordierite and biotite images reflect the content of Li, and muscovite and sericite contain both.The Peña Negra rocks contain less B and Li than many European Hercynian granitic complexes, and the anatectic process retained these elements in the restites rather than concentrating them in the granitic melt.
