Exempel på hur man kan använda ACANTHITE i en mening

• Three forms are known: monoclinic acanthite (α-form), stable below 179 °C, body centered cubic so-called argentite (β-form), stable above 180 °C, and a high temperature face-centred cubic (γ-form) stable above 586 °C.
• The name "argentite" sometimes also refers to pseudomorphs of argentite: specimens of acanthite which still display some of the outward signs of the cubic crystal form, even though their actual crystal structure is monoclinic due to the lower temperature.
• It is associated with other silver minerals and sulfides such as native silver, native arsenic, xanthoconite, stephanite, acanthite, tetrahedrite and chlorargyrite.
• Sylvanite is associated with native gold, quartz, fluorite, rhodochrosite, pyrite, acanthite, nagyagite, calaverite, krennerite, and other rare telluride minerals.
• As argentite cools below that temperature its cubic form is distorted to the monoclinic form of acanthite.
• Associated minerals include proustite, acanthite, native silver, tetrahedrite, galena, sphalerite and pyrite.
• The mineral occurs with massive habit, as elongated pseudododecahedral crystals up to , or as intergrowths with acanthite or naumannite.
• It occurs with acanthite, calcite, chalcopyrite, galena, pyrite, quartz, rhodochrosite, rhodonite, sphalerite and native tellurium.
• Stromeyerite and highly argentiferous tetrahedrite with some acanthite were the most important ore minerals in the upper levels, and argentiferous sphalerite had become the principal ore mineral in the lower levels of the mine.
• It occurs as a hydrothermal mineral in silver bearing veins in association with native silver, pyrargyrite, acanthite, stromeyerite, tetrahedrite, allemontite, galena, calcite and baryte.
• Associated minerals include acanthite, mckinstryite, galena, sphalerite, pyrite, chalcopyrite, stromeyerite, polybasite, pearceite, tetrahedrite–tennantite and native silver.
• The type locality is the Mollie Gibson Mine, Aspen, Aspen District (Roaring Fork District), Pitkin County, Colorado, where the mineral occurs in hydrothermal deposits formed at low to medium temperatures, associated with acanthite, tetrahedrite, native silver, proustite, quartz, baryte and calcite.
• Ore minerals include acanthite, arsenopyrite, cassiterite, cerussite, galena, limonite, pyragyrite, pyrite, semseyite, sphalerite, stannite, and stephanite.
