What else can I help you with?
An unidentified mineral that is softer than calcite that exhibits a metallic luster and cubic cleavage?
The mineral might be pyrite, which has a hardness lower than calcite, a metallic luster, and cubic cleavage. Pyrite's hardness is around 6-6.5 on the Mohs scale, compared to calcite's 3. It forms cubic crystals and has a brassy color.
Is calcite metallic?
No, calcite is not metallic. It is a mineral that exhibits a vitreous or pearly luster and is typically translucent to opaque. It is a non-metallic mineral.
Which mineral would not have a metallic luster?
A non-metallic mineral such as quartz or calcite.
Which mineral can be esily scratched by a fingernail has cleavage a metallic luster and has a black streak?
The mineral that fits this description is graphite. Graphite is very soft and can be easily scratched by a fingernail. It has a metallic luster and a black streak.
What is calcite luster?
Vitreous. Otherwise, no.

Does calcite have metallic luster?
No. It is transparent and does not contain metals.
Are metallic and glassy two types of cleavage?
No, metallic and glassy are not types of cleavage. Metallic refers to a type of luster in minerals, while glassy describes the appearance of a mineral's surface. Cleavage refers to the way a mineral breaks along planes of weakness.
How is mica and calcite be alike and how can they be different?
Mica and calcite are both minerals commonly found in Earth's crust. They both have distinct cleavage patterns, with mica typically having perfect basal cleavage and calcite having rhombohedral cleavage. However, they differ in chemical composition, as mica is a silicate mineral while calcite is a carbonate mineral. Additionally, mica displays a pearly luster and tends to be softer than calcite, which has a vitreous luster and can scratch glass.
Which mineral can be esily scratched by a fingernail has cleavage a metallic luster and has a black streak?
The mineral that fits this description is graphite. Graphite is very soft and can be easily scratched by a fingernail. It has a metallic luster and a black streak.
Does lodestone have cleavage?
No, lodestone does not have cleavage because it is a naturally occurring magnetite mineral with a metallic luster and is typically massive, lacking any distinct cleavage planes.
Explain how to identify a mineral using color luster streak hardness cleavage fracture?
Luster is the light reflection a mineral has, which can be broken down into categories like metallic, silky, and dull. The luster dictates what type of mineral it is.
What is calcite luster?
Vitreous. Otherwise, no.
Is calcite metallic or nonmetallic?
Calcite is a compound and therefore cannot be classified as a metal or nonmetal.
Which mineral can have a metallic and non metallic luster?
hematite can have both metallic and nonmetallic luster.
