  Argentite - LoveToKnow 1911
ARGENTITE, a mineral which belongs to the galena group, and is cubic silver sulphide (Ag 2 S).
It is occasionally found as uneven cubes and octahedra, but more often as dendritic or earthy masses, with a flish lead-grey colour and metallic lustre.
It occurs in mineral veins, and when found in large masses, as in Mexico and in the Comstock lode in Nevada, it forms an important ore of silver.

 Galena - LoveToKnow 1911
Since argentite (Ag 2 S) is isomorphous with galena, it is probable that the silver isomorphously replaces lead, but it is to be noted that native silver has been detected as an enclosure in galena.
Galena is of wide distribution, and occurs usually in metalliferous veins traversing crystalline rocks, clay-slates and limestones, and also as pockets in limestones.
Mention may also be made here of clausthalite (lead selenide, PbSe) and altaite (lead telluride, PbTe), which, with their lead-grey colour and perfect cubic cleavage, closely resemble galena in appearance; these species are named after the localities at which they were originally found, namely, Klausthal in the Harz and the Altai mountains in Asiatic Russia.

 JAIC 1992, Volume 31, Number 3, Article 7 (pp. 355 to 366)
Argentite formation in quantity is limited to silver objects buried in sediments for archaeological periods (Gettens 1963a; North and MacLeod 1986).
Argentite formation occurs when an object made of a silver-copper alloy is in a water-saturated deposit that contains SRB capable of maintaining reducing conditions and bacteria (perhaps ammonia producers) capable of oxidizing and thereby solubilizing both silver and copper atoms.
Argentite and jalpaite could, in principle, be stabilized when formed by corrosion of pure silver in a copper-rich environment (such as that associated with a mixture of silver and copper coins), but for practical purposes the presence of either argentite or jalpaite implies that the silver artifact originally contained significant copper.

 Argentite
Argentite, a silver sulfide mineral, is an important constituent of silver ore deposits.
Argentite is stable only above 179 deg C; thus, although few crystals found appear outwardly to be isometric, they are actually composed of acanthite, a chemically identical paramorph belonging to the monoclinic system.
Argentite's hardness is 2 - 2.5 and specific gravity is 7.2-7.4.

 Xanthoconite
Even where their bases are embedded in solid argentite, the quartz crystals are broken across at one end showing that they were formed and broken loose from their point of attachment before deposition of the silver sulphide.
Proustite, argentite, arsenopyrite and polybasite, in small perfect crystals rest upon the massive argentite, and the xanthoconite forms hemispherical masses up to 2 millimeters in diameter deposited around, and apparently later than, the proustite.
Although the main mass of the argentite forming the core of the specimen is without crystal form, there occur rarely on this, or attached to a quartz crystal, some scattered very minute.

 ACANTHITE/ARGENTITE (Silver Sulfide)
Argentite is a name applied to one polymorph (meaning many shapes) of Ag Acanthite and argentite have the same chemistry, Ag S, but different structures.
Argentite has an isometric structure and is only stable at temperatures above 173 degrees Celsius and if cooling from a melt, will form isometric crystals such as cubes, octahedrons and dodecahedrons.
Argentite has been historically used when referring to these crystals, but the acknowledgment of the true identity of the mineral requires the naming of these crystals (at lower temperatures) as acanthite.

Argentite is only stable above 179° C and is easily transformed into monoclinic acanthite.
I haven't been able to find a definite reference on it, but it seems to be probably that argentite is always transformed into acanthite when the temperature drops.
