Carbonate, Halide, Sulfate, and Sulfide Minerals

Sulfide minerals such as pyrite form under reducing conditions in the presence of organic matter. Jarosite and natrojarosite, Fe-bearing sulfate minerals, are good indicator minerals. Visual observation of morphology and crystal habit is often sufficient to identify many of the carbonate, sulfate, and halide minerals.

Mineral - Mineral - Sulfides: This important class includes most of the ore minerals. The similar but rarer sulfarsenides are grouped here as well. Sulfide minerals consist of one or more metals combined with sulfur; sulfarsenides contain arsenic replacing some of the sulfur. Sulfides are generally opaque and exhibit distinguishing colours and streaks. (Streak is the colour of a mineral…

Sulfide_mineral

2021-9-18 · Sulfide mineral. A sulfide mineral is a mineral containing sulfide (S 2-) as the major anion. Sulfides are economically important as metal ores. The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, and the sulfosalts (sulfur and a second anion such as arsenic).

Mineralogy of Sulfides | Elements | GeoScienceWorld

Sulfide minerals are compounds in which sulfur is combined as an anion with a metal (or semi-metal) cation or cations. The definition is commonly widened to include minerals in which the anion is As or Sb, sometimes together with S, and to include Se and Te minerals. The sulfosalts are a special group of the sulfide minerals that have a general ...

Reading: Classifying Minerals | Geology

Minerals are classified according to their chemical properties. Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S 2–.
