Zhangpeishanite

Zhangpeishanite 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 Zhangpeishanite rather than just read about it. In short: Zhangpeishanite is a mineral named after Zhang Peishan (Chinese: 张培善), a Chinese mineralogist at the Institute of Geology of the Chinese Academy of Sciences, in recognition of his contributions to studying the mineralogy Bayan Obo deposit, where the mineral is mined. The Bayan Obo deposit is also known for being a world class deposit.

Key takeaways

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

Reference excerpt

Zhangpeishanite is a mineral named after Zhang Peishan (Chinese: 张培善), a Chinese mineralogist at the Institute of Geology of the Chinese Academy of Sciences, in recognition of his contributions to studying the mineralogy Bayan Obo deposit, where the mineral is mined. The Bayan Obo deposit is also known for being a world class deposit. The mineral got approved by the IMA in 2006 but was published two years after its approval. The mineral consists of barium chloride fluoride.

Properties Some of the data collected about zhangpeishanite were carried out on a synthetic equivalent of the mineral, such as cleavage and refractive index, due to zhangpeishanite's minute grain size. The mineral is isostructural with matlockite. It is a member of the matlockite group, and it is the barium dominant analogue of rorisite and matlockite. It is associated with barite, hematite, norsethite and fluorite. The inclusions form as bands within fluorite. The mineral occurs in fluorite as inclusions, up to 100 μm. However, they are typically much smaller, about 50 μm. It consists of barium mostly (71.21%), chlorine (18.94%) and fluorine (9.85%). Singular crystals can be obtained at 1500 K by solid-state reaction between BaF2 and BaCl2.

Worked examples

Example 1 — a first encounter with Zhangpeishanite

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

In research: Zhangpeishanite 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 Zhangpeishanite 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: Zhangpeishanite is common in secondary-school and first-year university syllabi. It links to neighbouring topics Barium minerals, Chloride fluorides, Tetragonal minerals, so understanding it makes those chapters shorter.
In everyday life: Look for Zhangpeishanite 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 Zhangpeishanite in simple terms?

Why does Zhangpeishanite 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 Zhangpeishanite?

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.
