Strashimirite

Strashimirite 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 Strashimirite rather than just read about it. In short: Strashimirite (IMA symbol: Ssh) is a rare monoclinic mineral containing arsenic, copper, hydrogen, and oxygen. It has the chemical formula Cu8(AsO4)4(OH)4·5(H2O).

Key takeaways

Strashimirite 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 Strashimirite to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Strashimirite from memory before moving on to harder problems.

Reference excerpt

Strashimirite (IMA symbol: Ssh) is a rare monoclinic mineral containing arsenic, copper, hydrogen, and oxygen. It has the chemical formula Cu8(AsO4)4(OH)4·5(H2O). This mineral was discovered in Zapachitsa (Zapacica) copper deposit, Svoge, Sofia Oblast, Bulgaria in 1960, by Bulgarian mineralogist Jordanka Minčeva-Stefanova. She named it after Strashimir Dimitrov (1892–1960), Professor in Mineralogy and Petrography at Sofia University "St Kliment Ohridski", Bulgaria. The International Mineralogical Association approved it as a new mineral in 1968. It occurs as a secondary mineral phase in the oxidation zone of copper arsenide deposits. It occurs associated with tyrolite, cornwallite, clinoclase, euchroite, olivenite, parnauite, goudeyite, arthurite, metazeunerite, chalcophyllite, cyanotrichite, scorodite, pharmacosiderite, brochantite, azurite, malachite and chrysocolla. Although it remains quite rare, strashimirite has subsequently been identified in a number of locations including: Novoveska Huta in the Slovakia; on the west flank of Cherbadung (Pizzo Cervandone), Binntal, Valais, Switzerland; in Kamsdorf and Saalfeld, Thuringia, Germany; the Clara mine, near Oberwolfach, Black Forest, Germany; in the Richelsdorf Mountains, Hesse, Germany; Cap Garonne mine, near le Pradet, Var, and Triembach-au-Val, Haut-Rhin, France; Wheals Gorland and Unity, Gwennap, Cornwall, England; the Tynagh mine, near Loughrea, Co. Galway, Ireland; the Majuba Hill mine, Antelope district, Pershing Co. Nevada, US; and the Centennial Eureka mine, Tintic district, Juab Co., Utah, US.

Worked examples

Example 1 — a first encounter with Strashimirite

Start with the simplest possible case. Write down what Strashimirite 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 Strashimirite 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 Strashimirite 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 Strashimirite

In research: Strashimirite 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 Strashimirite 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: Strashimirite is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arsenate minerals, Copper minerals, Hydroxide minerals, so understanding it makes those chapters shorter.
In everyday life: Look for Strashimirite 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.

Frequently asked questions

What is Strashimirite in simple terms?

Strashimirite (IMA symbol: Ssh) is a rare monoclinic mineral containing arsenic, copper, hydrogen, and oxygen. It has the chemical formula Cu8(AsO4)4(OH)4·5(H2O).

Why does Strashimirite matter?

Because it connects several earth science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Strashimirite?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Strashimirite.
