The mineral you are describing is calcite. Calcite contains both oxygen and carbon, and it has a hardness of 3 on the Mohs scale, making it softer than fluorite (hardness of 4) but harder than gypsum (hardness of 2). Additionally, calcite is known for its characteristic effervescence when it comes into contact with dilute acid, due to the release of carbon dioxide gas.
The fourth mineral on Mohs' Scale of Hardness is fluorite. It has a hardness of 4 on the scale.
The mineral being described is likely calcite. Calcite is composed of oxygen and carbon, has a hardness between fluorite and gypsum, and fizzes quickly when in contact with acid due to its reaction to the acid's carbonate content.
Fluorite is unable to scratch feldspar, quartz, corundum, diamond, or any other mineral with a Mohs hardness greater than 4.
Fluorite is a mineral, not a rock. It is a commonly occurring mineral that is composed of calcium and fluorine. Rocks are made up of one or more minerals.
Fluorite is a mineral and should not be tasted as it can be harmful if ingested. It is not recommended to taste or consume any mineral specimens.
Calcite (CaCO3).
Fluorite is a mineral.
The mineral described is likely fluorite, which is a non-silicate mineral containing fluorine. When exposed to ultraviolet light, fluorite can exhibit fluorescence or glow due to the presence of impurities or crystal defects that interact with the light.
Fluorite is the mineral composed of calcium and fluorine.
The fourth mineral on Mohs' Scale of Hardness is fluorite. It has a hardness of 4 on the scale.
Fluorite is a fluorescent mineral.
NO
From a mineralogical perspective, fluorite is an evaporite mineral that contains one calcium ion and two fluorine ions. Calcium may also be substituted partially accounting for different colours of the mineral but it is usually purple.
