Muscovite from
Conrad Hill Mine (Dodge Hill Mine), Cid Mining District, Davidson County, North Carolina, USA


Locality type:Mine
Classification
Species:Muscovite
Formula:KAl2(AlSi3O10)(OH)2
Formation:Primary
Comments:The listing of muscovite as a mineral at Conrad Hill can be misleading. What is present is a very fine grained sericite "schist" according to the literature, but certainly a phyllite. There are no visible mica flakes under a 15x hand lens. The rock resembles a creamy pale beige or greenish beige serpentine. It creates patches along with milky quartz and coarse cleavages of red-brown siderite. This combination makes attractive "yard rocks". Note that this rock is confined to the ore body and is absent in the country rock.
Quality for species:Rock forming mineral/non-crystalline/little interest for collectors.(##)
Abundance at site:Very common
Confirmation
Validity:Confirmed
Confirmation Methods:Optical Analysis
