Sulfate mineral

Sulfate mineral is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sulfate mineral rather than just read about it. In short: The sulfate minerals are a class of minerals that include the sulfate ion (SO2−4) within their structure. The sulfate minerals occur commonly in primary evaporite depositional environments, as gangue minerals in hydrothermal veins and as secondary minerals in the oxidizing zone of sulfide mineral deposits.

Key takeaways

Sulfate mineral belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Sulfate mineral to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sulfate mineral from memory before moving on to harder problems.

Reference excerpt

The sulfate minerals are a class of minerals that include the sulfate ion (SO2−4) within their structure. The sulfate minerals occur commonly in primary evaporite depositional environments, as gangue minerals in hydrothermal veins and as secondary minerals in the oxidizing zone of sulfide mineral deposits. The chromate and manganate minerals have a similar structure and are often included with the sulfates in mineral classification systems.

Sulfate minerals include:

Anhydrous sulfates Barite BaSO4 Celestite SrSO4 Anglesite PbSO4 Anhydrite CaSO4 Hanksite Na22K(SO4)9(CO3)2Cl Hydroxide and hydrous sulfates Gypsum CaSO4·2H2O Chalcanthite CuSO4·5H2O Kieserite MgSO4·H2O Starkeyite MgSO4·4H2O Hexahydrite MgSO4·6H2O Epsomite MgSO4·7H2O Meridianiite MgSO4·11H2O Melanterite FeSO4·7H2O Antlerite Cu3SO4(OH)4 Brochantite Cu4SO4(OH)6 Alunite KAl3(SO4)2(OH)6 Jarosite KFe3(SO4)2(OH)6 Löweite Na12Mg7(SO4)13·15H2O

Nickel–Strunz classification -07- sulfates

IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009). This list uses it to modify the Classification of Nickel–Strunz (mindat.org, 10 ed, pending publication).

Abbreviations: "*" – discredited (IMA/CNMNC status). "?" – questionable/doubtful (IMA/CNMNC status). "REE" – Rare-earth element (Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) "PGE" – Platinum-group element (Ru, Rh, Pd, Os, Ir, Pt) 03.C Aluminofluorides, 06 Borates, 08 Vanadates (04.H V[5,6] Vanadates), 09 Silicates: Neso: insular (from Greek νησος nēsos, island) Soro: grouping (from Greek σωροῦ sōros, heap, mound (especially of corn)) Cyclo: ring Ino: chain (from Greek ις [genitive: ινος inos], fibre) Phyllo: sheet (from Greek φύλλον phyllon, leaf) Tekto: three-dimensional framework Nickel–Strunz code scheme: NN.XY.##x NN: Nickel–Strunz mineral class number X: Nickel–Strunz mineral division letter Y: Nickel–Strunz mineral family letter ##x: Nickel–Strunz mineral/group number, x add-on letter

Worked examples

Example 1 — a first encounter with Sulfate mineral

Start with the simplest possible case. Write down what Sulfate mineral claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sulfate mineral before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sulfate mineral ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sulfate mineral

In research: Sulfate mineral appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sulfate mineral in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sulfate mineral is common in secondary-school and first-year university syllabi. It links to neighbouring topics Sulfate minerals, so understanding it makes those chapters shorter.
In everyday life: Look for Sulfate mineral outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
