Locality type: Pit Classification Species: Phlogopite Formula: KMg3 (AlSi3 O10 )(OH)2 Formation: Primary Comments: Large essentially black crystals to over 9 cm across and more than 15 cm long in marble associated with tough, massive, dark augite/gahnite rock in the East Ore Vein. Good crystals at the contacts of these rocks. 2008 EDS analysis shows abundant Mg plus much Fe, Zn and Mn; XRD with 10.3 Å spacing indicates a phlogopite-3T polytype, probably mixed with some phlogopite-1M, seeing that the (001) reflection is broad ranging down to 9.2 Å and the other peaks are sharp (Van King communication 2016). Habit: stubby to elongated, tapered prismatic with pseudohexagonal outline rarely terminated by pinacoids Colour: black Quality for species: Good crystals or rich for species - important (!)
