Calcium carbonate forms as both Aragonite and Calcite, and these two minerals only differ in their crystallization.Calcite, the more common mineral, forms in trigonal crystals, whereas Aragonite forms orthorhombic crystals. On occasion, crystals of Aragonite and Calcite are too small to be individually determined, and it is only possible to distinguish these two minerals with optical or x-ray ...

General Acanthite Information. Low-temperature sulfide veins and in zones of secondary enrichment. Freiberg, Schneeberg, Annaberg, Germany. Link to MinDat.org Location Data. From the Greek, akanta, meaning "arrow." After the Latin, argentum, meaning "silver". Argentite is stable above 179 C. Acanthite is stable below 179 deg. C.
Argentite is the high-temperature form of acanthite. Like several other sulfides, selenides, and tellurides of silver and copper, argentite forms isometric crystals at high temperatures. Upon cooling these crystals invert from isometric (cubic) to monoclinic structures while remaining unchanged in external appearance.
Argentite (cubic silver sulphide) is only stable above 173 C. The mineral form of silver sulphide (except very deep, I guess) is the monoclinic form: acathite.

The name 'argentite' refers to the high-temperature form of silver sulphide, only stable over 177°C. Below this temperature, any samples of 'argentite' convert to acanthite. The name argentite is therefore used (confusingly) by some to describe pseudo-cubic pseudomorphs of silver sulphide (acanthite) where the original crystal form of the high-temperature cubic argentite has remained.

Silver is found in lead, zinc, gold and copper ore deposits. The most important ore mineral of silver is argentite (Ag2S, silver sulfide). Silver is commonly extracted from ore by smelting or chemical leaching. Uses. Silver has been used for thousands of years for jewelry and decorative items of all types. Likewise, it has been used for silverware.

Argentite is the stable form above that temperature. As argentite cools below that temperature its cubic form is distorted to the monoclinic form of acanthite. Below 173 °C acanthite forms directly. [1][4] Acanthite is the only stable form in normal air temperature.
