Structure: Fractures

Alteration: Silicification

Deposit: The massive Mn-oxide minerals occur in a zone up to 8 m thick. The north (footwall) side is a quartz-rich rock that resembles quartzite (recrystallized). The south side of the zone is mainly granodiorite porphyry, but a small amount of the quartz-rich rock is present also. The attitude of the footwall contact is N 45 w, 75 sw. The manganese zone does not appear to be laterally extensive; possibly it is cut out by faults or dikes.

Deposit type: Polymetallic veins

Rock formation(s): Pumpernickel
