Halite (Salt) is the mineral that has cubic cleavage with a salty taste.
Following are the characteristics of Halite:-
- Colors: white, tinted blue, reddish
- Hardness: 2.5
- Specific gravity: 2.1 - 2.6
- Perfect cubic cleavage
Halite, sodium chloride (NaCl), is the most abundant of the EVAPORITE minerals.
- As rock salt, it is a major source of sodium and chlorine;
- As table salt, it is used to flavor food and is an essential dietary constituent
