1. It also occurs in carbonatites and chlorite, biotite and phlogopite . 2. Consumption of muscovite and phlogopite splittings was about 308 t in 2008. 3. Phenocrysts in the rocks contain clinopyroxene, olivine, orthopyroxene and phlogopite . 4. The phlogopites are the glittering minerals surrounded by the green groundmass of olivine . ]] 5. Clintonite and its iron-rich variety xanthophyllite are sometimes considered the calcium analogues of the phlogopites . 6. It occurs associated with aegirine, riebeckite, barite, fluorite, albite, phlogopite and magnetite. 7. Phlogopite built-up mica is preferred because it wears at the same rate as the copper segments.8. The rock has a porphyritic texture with large crystals of orthopyroxene and phlogopite set in a fine grained matrix. 9. Phlogopite and / or potassic amphibole probably are typical in the sources from which many such magmas have been derived.10. Impure vermiculite may contain, apart from asbestos, also minor diopside or remnants of the precursor minerals biotite or phlogopite .
