acanthite
n. C2 Proficiency acan·thite
n. a type of silver ore that is usually found in dark, shiny, or white colors. It is a natural form of silver sulfide.
n. a natural mineral form of silver sulfide, typically appearing as dark gray to black, metallic, or white. It is a primary ore of silver and is often found in hydrothermal veins.
The miners found a large deposit of acanthite in the mountain.
Geologists identified the dark, metallic mineral as acanthite, which is a common source of silver in the region.
The presence of acanthite in the geological strata indicates a history of high-temperature hydrothermal activity that deposited silver sulfides in the surrounding rock formations.
