Several minerals are evaporites, and therefore, there is not just one mineral composition but a different one for each mineral.
It is not a rock but an evaporite mineral.
Evaporite minerals are water-soluble mineral sediments that were formed from precipitation. The three common evaporite minerals are gypsum, anhydrite and halite.
it means a naturally-occaring, inorganic solid that has a crystal structure and a definite chemical composition
And their texture, which can be aphanitic, phaneritic, glassy, or porphyritic. mineral composition and crystal texture
Among other things, yes, mineral composition is a common part of geology.
It is not a rock but an evaporite mineral.
Evaporite minerals are water-soluble mineral sediments that were formed from precipitation. The three common evaporite minerals are gypsum, anhydrite and halite.
Sodium chloride as a mineral (halite) has two origins: sedimentary or evaporite mineral.
Gypsum is a sulfate and not a silicate. It is an evaporite mineral and a soft mineral that is composed of calcium.
Gypsum
Halite (sodium chloride) is not a clastic mineral; it is an evaporite.
Sodium chloride is a mineral (halite) obtained by the evaporation of water (an evaporite).
Each known mineral has a specific chemical composition.
The color of a mineral sample is determined by its chemical composition
An evaporite is a sedimentary rock that is soluble in water. It occurs where there is a lake that evaporates more quickly than rain or river water enters the lake. The water evaporates and the rich mineral sediment becomes a rock or a crystal.
the composition of luster is limstone
it means a naturally-occaring, inorganic solid that has a crystal structure and a definite chemical composition
