Gormanite

Gormanite 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 Gormanite rather than just read about it. In short: Gormanite is a phosphate mineral with the formula (Fe,Mg)3Al4(PO4)4(OH)6·2H2O. It was named after the University of Toronto professor Donald Herbert Gorman (1922–2020).

Key takeaways

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

Reference excerpt

Gormanite is a phosphate mineral with the formula (Fe,Mg)3Al4(PO4)4(OH)6·2H2O. It was named after the University of Toronto professor Donald Herbert Gorman (1922–2020).

Occurrence It was first described in 1981 for occurrences in Rapid Creek and Big Fish River in the Dawson Mining District, Yukon Territory, Canada. At the type localities it occurs as veins in iron phosphate nodules. In the Bisbee, Arizona occurrence, it occurs as large crystals within fractures in a tonalite intrusive. It has also been reported from near Newport, Sullivan County, New Hampshire, and the Charles Davis pegmatite, Groton, Grafton County, New Hampshire. It also has been reported from the Tsaobismund pegmatite, south of Karibib, Namibia.

Worked examples

Example 1 — a first encounter with Gormanite

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

In research: Gormanite 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 Gormanite 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: Gormanite is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aluminium minerals, Dihydrate minerals, Iron(II) minerals, so understanding it makes those chapters shorter.
In everyday life: Look for Gormanite 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 Gormanite in simple terms?

Gormanite is a phosphate mineral with the formula (Fe,Mg)3Al4(PO4)4(OH)6·2H2O. It was named after the University of Toronto professor Donald Herbert Gorman (1922–2020).

Why does Gormanite 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 Gormanite?

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.
