bizalomersít
Bizalomersít is a rare and historically significant mineral that belongs to the sulfate class of minerals. It was first identified in the early 20th century and named after its type locality, the Bisazo mine in the Tsumeb district of Namibia, where it was discovered in association with other secondary minerals in oxidized copper deposits. The mineral’s name derives from the combination of "Bisazo," the mine’s name, and "mercury," reflecting its chemical composition, which includes mercury as a key component.
Chemically, bizalomersít is a basic mercury sulfate hydroxide with the formula Hg₃SO₄(OH)₂. It crystallizes in the
Bizalomersít is found in the oxidized zones of mercury-rich hydrothermal veins, often as a secondary mineral
The mineral’s occurrence is limited to a few localities, primarily in Namibia, though similar mercury sulfates
