Reedmergnerite

Reedmergnerite 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 Reedmergnerite rather than just read about it. In short: Reedmergnerite is a borosilicate mineral named in honor of Frank S. Reed and John L.

Key takeaways

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

Reference excerpt

Reedmergnerite is a borosilicate mineral named in honor of Frank S. Reed and John L. Mergner. It is approved by the International Mineralogical Association but was first described prior to the association's formation, first published in 1955. Although it is approved, it got grandfathered, meaning the name reedmergnerite is still believed to refer to a valid species. Reedmergnerite has a synthetic potassium analogue.

Properties Reedmergnerite is a member of the feldspar group. It grows along bedding laminations as authigenic crystals, as a stubby prismatic to platy crystals. It is wedge-shaped usually, and it may have jagged terminations. Crystals grow in aggregates, and a singular crystal's size can reach up to 10 cm. It is isostructural with low albite. It does not exhibit anisotropy. The mineral has been synthesized using gels. The procedure occurred hydrothermally. The gels that were used in the synthesis contained a 10% weight excess of silicon dioxide. While the pressure and the temperature were constant, the degree of boron and silicon order increased with time, though both lower water content and pressure decrease the rate of ordering. The mineral's ordering behavior occurs to be insensitive to the co-existing fluid's composition.

Environment and mining Although it has three type localities, the most important of those is at Joseph Smith No. 1 well in the United States. The associated minerals at the type locality are eitelite, searlesite, crocidolite, leucosphenite and shortite. It happens to occur in dolomitic shale mostly. However, it can also occur in brown dolomitic rock and black oil shale as well.

Worked examples

Example 1 — a first encounter with Reedmergnerite

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

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