Vote for your favorite mineral in #MinCup26! - Sphalerite vs. Anorthite
Both zinc ore Sphalerite and calcium plagioclase feldspar Anorthite have perfect cleavage that will split cleanly if you hit them with a hammer, but only one can claim a larger split of your votes!

Name(s) in local language(s):
Mina Teresita (Mina del Aramo)


Epigenetic, carbonate-hosted Cu/Co/Ni deposit.

Host rocks: Black fetid Namurian bituminous limestones (700 meters thick).

Complex mineralization with three successive primary stages and an important later supergene stage:

1) Pyrite-marcasite-bravoite: Co/Ni sulfarsenides and arsenides in dolomite; associated with acanthite. Cobaltite, safflorite, gersdorffite.

2) Intermediate stage: Tennantite and sphalerite in quartz/dolomite.
Renierite. Chalcopyrite (with briartite inclusions) and talnakhite replacing early assemblage. Tennantite and sphalerite replace cobaltite and safflorite.

3) Cu/Fe sulphides: Chalcopyrite, talnakhite, and bornite. Chalcocite, djurleite, digenite, covellite.

4) Oxidation sequence: Cementation copper sulfides, native elements, and oxidation minerals.

Production and reserves: 200,000 tons extracted. 400,000 tons ore reserves @ 1-3% Ni and 1-3% Co, 1-20% Cu.
