Exempel på hur du använder ARGENTITE i en mening

• Silver is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite.
• 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.
• As argentite cools below that temperature its cubic form is distorted to the monoclinic form of acanthite.
• Deposits of freieslebenite can generally be located in proximity with minerals argentite, siderite, freibergite, polybasite, and aramayoite.
• Ore deposits are found in the Permian limestone and consist of supergene replacement minerals argentite and cerargyrite along the bedding.
• In the oxidized zone, ore minerals include native silver and argentite have been replaced by cerargyrite, iodobromite, bromyrite, embolite, and iodyrite.
• The ore took the form of native silver, argentite, chlorargyrite, and bromargyrite, deposited in folds in impervious shale beds overlying intrusions of monzonite porphyry of the Mogollon-Datil volcanic field.
