WebAug 30, 2024 · Bunya phyllite is well foliated and contains quartz veins and layers parallel to foliation. Rock matrix contains alternating micaceous bands and very small quartz-rich layers and quartz veins. Mineralogy was determined by using hand lens and is primarily composed of quartz and a weathered phyllosilicate mineral (biotite and/or chlorite).
