β Actinolite Formula: ◻Ca2(Mg4.5-2.5Fe0.5-2.5)Si8O22(OH)2 Description: Coatings on joint cracks in Cornelia quartz monzonite just west of the Gibson Arroyo. Presumably no relation to the ore deposit, though nearby quartz monzonite has been somewhat albitized.
|
β Andalusite Formula: Al2(SiO4)O Habit: Minute, prismatic Colour: Pale pink Description: One specimen only - the same specimen of Cardigan Gneiss from west of the Gibson Arroyo fault that contained the topaz.
Pleochroic: a (rose pink) = 1.640, Γ (colorless) = 1.645, y (colorless) = 1.648, with birefringence 0.008, parallel extinction, large 2V, prismatic cleavage. |
β Topaz Formula: Al2(SiO4)(F,OH)2 Habit: Microscopic Description: Rock forming mineral in the Cardigan gneiss, near contact with Cornelia quartz monzonite west of the Gibson Arroyo fault. One specimen only. |
