Sulfates Mineral

December 13, 2018

Minerals which have a composition of SO₄^2- a mineral sulfate. Sulfate is included in 7 groups of minerals, because sulfate is anionic, or more than 1 element that joins and has a negative charge. The elements that make up the sulfate content are Sulfur and Oxygen when seen through the periodic table as follows.

Sulfate and oxygen are anions, so there is no doubt that when they combine they will make anionic.

The earth's crust is certainly composed of rocks, but rocks are also composed of minerals, a term that is often heard is "Rock Forming Minerals". The rocks that make up the earth's crust contain very little sulfate compared to other minerals. Sulphate ranks 15th in terms of its spread on continental plates. The first sequence is dominated by oxygen. The percentage of sulfur in the continental plate is only 0.03%.

Mineral sulfates are also formed in hydrothermal, or evapolarization. The formation of Hydrothermal is the settling of minerals dissolved in water caused by evaporating water, of course minerals will not evaporate with water so that it will form crystals, for example calesit, barite, crocite. Water that enters into the rock will form a vein, until the minerals dissolved in the water will be trapped in the veins that have been formed in the gaps / veins earlier.

the illustration above can be drawn from the possibility that water dissolving minerals evaporates due to heat in the earth or geothermal

Evapolarization is caused by the evaporation of seawater so that it leaves minerals in its base, Sea water generally contains many minerals to more clearly please see the following picture

Because the amount of minerals contained in sea water during normal conditions so it is very possible that many minerals contain unique minerals. For example, the mineral is Epsomite, in order to understand the process clearly, please see the illustration as follows.
