Ardaite is a very rare sulfosalt mineral with chemical formula Pb19Sb13S35Cl7 in the monoclinic crystal system, [2] [3] named after the Arda River, which passes through the type locality. [4] It was discovered in 1978 and approved by the International Mineralogical Association in 1980. [5] [6] [7] It was the second well-defined natural chlorosulfosalt, after dadsonite. [8]

Greenish gray or bluish green in color, its luster is metallic. Ardaite occurs as 50  µm fine-grained aggregates of acicular crystals associated with galena, pyrostilpnite, anglesite, nadorite, and chlorine-bearing robinsonite and semseyite, in the Madjarovo polymetallic ore deposit in Bulgaria. Ardaite has a hardness of 2.5 to 3 on Mohs scale and a density of approximately 6.44. [2]

The type locality is the Madjarovo polymetallic ore deposit in the Rhodope Mountains. [9] [10] Later its occurrence was proved in the Gruvåsen deposit, near Filipstad, Bergslagen, Sweden. [6]

<span class="mw-page-title-main">Germanite</span>

Germanite is a rare copper iron germanium sulfide mineral, Cu26Fe4Ge4S32. It was first discovered in 1922, and named for its germanium content. It is only a minor source of this important semiconductor element, which is mainly derived from the processing of the zinc sulfide mineral sphalerite. Germanite contains gallium, zinc, molybdenum, arsenic, and vanadium as impurities.

It is classified in the ugrandite group alongside the other calcium-bearing garnets andradite and grossular.

<span class="mw-page-title-main">Adamite</span>

Adamite is a zinc arsenate hydroxide mineral, Zn2AsO4OH. It is a mineral that typically occurs in the oxidized or weathered zone above zinc ore occurrences. Pure adamite is colorless, but usually it possess yellow color due to Fe compounds admixture. Tints of green also occur and are connected with copper substitutions in the mineral structure. Olivenite is a copper arsenate that is isostructural with adamite and there is considerable substitution between zinc and copper resulting in an intermediate called cuproadamite. Zincolivenite is a recently discovered mineral being an intermediate mineral with formula CuZn(AsO4)(OH). Manganese, cobalt, and nickel also substitute in the structure. An analogous zinc phosphate, tarbuttite, is known.
