Next mineral group mapping: SULFIDES AND SULFOSALTS

P.S., I'm aware that a black canvas with dots on it isn't all too helpful, so I'll be including a copy of the topographic map on these as well so you can see where these are...

SULFIDES Pyrite - FeS2 - (Dark Gold) Chalcopyrite - CuFeS2 - (Darker Brown-Gold) Galena - PbS - (Light Steel Blue) Sphalerite - ZnS - (Light/Faded Green-Blue) Cinnabar - HgS - (Cinnabar-Burgundy Red) Molybdenite - MoS2 - (Light/Faded Lilac-Gray) HIGHER ARSENIDES Arsenopyrite - FeAsS - (Brownish-Orange) Skutterudite - (Ni,Co,Fe)As3 - (Cobalt Blue) SULFOSALTS Polybasite - (Ag,Cu)16Sb22S11 - (Grey-Camo Green) Stephanite - Ag5SbS4 - (Dark Amythest-Grey) Tetrahedrite - Cu12Sb4S13 - (Greenish-Lemon Yellow) Pyrargyrite - Ag3SbS3 - (Dark Crimson)

More mineral groups coming up ! I've got ~105 to map!

Acanthite

Acanthite is a silver sulphide and one of the most important ores of silver.

Its name comes from the Greek word ‘Akantha’ meaning ‘thorn’ in reference to the spiky appearance of some of the crystal formations.

At temperatures above 177°C it forms cubic crystals which were previously considered to be an entirely different mineral and given the name Argentine however nowdays it’s understood to be just a different form of Acanthite.

Acanthite forms in hydrothermal cans alongside other minerals such as silver, galena, pyrargyrite and Proustite.

The most notable location for Acanthite is the Comstock lode in Nevada which was so rich in silver that a branch of the US mint was established in a nearby town to coin its output.

The final two photos here are a piece of quartz that has some sort of silvery mineral formed on it that is most likely Acanthite.

Pyrargyrite

Named after the Greek for fire silver, this rare ore mineral is usually a deep grey to black in reflected light and a powerful ruby red in transmitted light, though specimens should be stored in the dark as they become more opaque with prolonged exposure to light. Popular with collectors, it is too soft (2.5 on Mohs scale) for gem use. A salt of silver, sulphur and antimony it is also somewhat toxic to the touch (I wouldn't lick it like I do some rocks), as is its cousin Proustite (aka ruby silver, see http://bit.ly/1VPbDb7) from whom it is tricky to distinguish (though a feature known as streak, the colour of the powder left behind when a sample is scraped across an unglazed tile will do so....pyrargyrite is purple, proustite crimson). Its lustre (amount of light reflected from the surface) is very bright, of a kind named adamantine by mineralogists after the exceptional lustre of adamas (diamond in Greek).

These minerals were first mentioned in 1546 by Georgius Agricola in the first ever geology and mining textbook, De re metallica. They form in the oxidised zone of hydrothermal (vein type) silver deposits where supergene enrichment by hot Earth fluids has removed components like silica from the rocks, leaving them enriched in metals. It precipitates as a late stage low temperature phase. These zones are often a determining factor in the viability of a proposed mine, as they allow a higher cashflow to be frontloaded into the operation. Famous localities include the Harz Mountains of Germany, Mexico, Chile and the western USA.

Unlike the more usual transparent ruby red specimens here we have a cluster of crystals with an iridescent patina caused by a thin coating of the mineral Chalcocite via the optical game labelled thin film iridescence (think petrol on a puddle). It was mined in Saxony in Germany and measures 2.3 x 2.0 x 1.5 cm

Hi @cool-kiryuin​ ! This is a very good question im super happy to answer! 

I personally love too "strange" and unknown minerals, so I'll try to make this list as complete as possible!

(it will be a LONG list under the cut. but i cant help myself!)

COLOUR/ASPECT:

Volkonskoite

formula: Ca0.3(Cr,Mg,Fe)2((Si,Al)4O10)(OH)2 · 4H2O hardness: 1 to 2 nickel-strunz classification: 9.EC.40 colours:blue-green to olive-green

Volkonskoite is a... blob of colour. It has a waxy lustre and can be very shiny! It's also very soft and can be scratched easily, but its pretty cute...

Conichalcite

formula: CaCu(AsO4)(OH) hardness: 4½ nickel-strunz classification: 8.BH.35 colour: green, VERY green

this mineral is VERY VERY GREEN. it has the most beautiful green colour and almost always form in botryoidal form (spheres). very pretty. very very pretty.

Serandite

formula: NaMn2+2Si3O8(OH) hardness: 5 to 5½ nickel-strunz classification: 9.DG.05 colour: salmon pink, peach pink, rose-red

it's a bit harder mineral than the ones before, it has a very peculiar orange-red-pink colour! it can be both transparent and opaque.

Pyrargyrite

formula: Ag3SbS3 hardness: 2½ nickel-strunz classification: 2.GA.05 colour: dark red/silver

composed of 60% by silver, its an incredible mineral! under direct light has a silver shine, but if lighted in the right way (mostly from behind or from some angles) its a beautiful dark red colour! 

Proustite is a similiar mineral, but instead of Sb there is As!

Diaboleite

formula: Pb2CuCl2(OH)4 hardness: 2½ nickel-strunz classification: 3.DB.05 colour: deep blue

kinda soft but LOOK AT THAT BLUE!

Eulytine

formula: Bi4(SiO4)3 hardness: 4½ nickel-strunz classification: 9.AD.40 colour: orange, lime, colourless

this mineral can be in two forms: ORB or pyramid! or both together at the same time.

Mcalpineite

formula: Cu3(Te6+O6) hardness: 3 nickel-strunz classification: 7.DE.55 colour: bright green

this mineral only forms in small spheres all pressed together. its cute.

FORMATION:

Triazolite

formula: NaCu2(N3C2H2)2(NH3)2Cl3·4H2O hardness: 2 nickel-strunz classification: none colour: deep blue

called like that because its one of the only two triazolate minerals (the other being chanabayaite). formation is similiar to the Shilovite (my oc) one- guano reacting tochalcopyrite. very very rare.

Similiar minerals are Joanneumite, Shilovite and Ammineite.

Minium

formula: Pb3O4 hardness: 2½ nickel-strunz classification: 4.BD.05 colour: bright orange, bright red

other to have a very cool name, it's the (violent) oxidation of lead, usually by lead mines taking fire. its INCREDIBLY heavy!

Pitticite

formula: (Fe, AsO4, H2O)? varies hardness: 2 to 3 nickel-strunz classification: none colour: yellow to red to brown

amorphous gel (just like opal). it means its very hard to break and has no cleavage (points where it can break easily) but its not really a mineral more of a "mineraloid". grows from oxidation of arsenic minerals, usually in flooded mines and hot spring waters.

COMPOSITION AND PROPERTIES

Faizievite

formula: K2Na(Ca6Na)Ti4Li6[Si6O18]2[Si12O30]F2 hardness: 4 to 4½ nickel-strunz classification: 9.CM.10 colour: colourless (blue in UV light)

unique combination of elements, related to both Beryl group and Osumilite group.

Majzlanite

formula: K2Na(ZnNa)Ca(SO4)4 hardness: 2 to 3 nickel-strunz classification: none yet colour: grey with a blue hint

unique combination of elements and new structure! also one of the newest gems to be "officialized", this year in 2020!

Johnkoivulaite

formula: Cs[Be2B]Mg2Si6O18 hardness: 7½ nickel-strunz classification: none yet colour: colourless/dark blue, indigo or purple

unique combination of elements, a very new gem soon to be published (probably next year) but its most interesting property is its incredible pleochroism! (pleochroism is the property of a mineral, depending on where you watch it, it "changes" colours. NOT like alexandrite, its a different thing!) so this mineral is both colourless and dark blue (or indigo or purple depending on the gem) at the same time! it just changes the angle from where you watch it! Related to beryl.

Tlalocite

formula: Cu10Zn6(Te6+O4)2(Te4+O3)(OH)25Cl · 27H2O hardness: 1 nickel-strunz classification: 7.DE.20 colour: aqua blue

named after Tlaloc, the Aztec god of rain and water. has a high water content and its not brittle and breakable like most minerals but more gummy and sectile, not breaking in pieces but slicing if cut.

Nierite

formula: Si3N4 hardness: 9 nickel-strunz classification: 1.DB.05 colour: unknown. pure its colourless, but can be brown. 

incredibly rare mineral, found only in stardust and meteorites. very very hard. related to Diamond and Moissanite.

I hope this helped! if you need more infos, or more minerals, just ask again and i will aswer!
