Loveringite

Loveringite 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 Loveringite rather than just read about it. In short: Loveringite is a rare metallic oxide mineral of the crichtonite group with the chemical formula (Ca,Ce)(Ti,Fe,Cr,Mg)21O38. It is a late-stage magmatic mineral, formed in the residual melt of mafic layered intrusions in either the olivine-chromite, pyroxene, or plagioclase-rich layers.

Key takeaways

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

Reference excerpt

Loveringite is a rare metallic oxide mineral of the crichtonite group with the chemical formula (Ca,Ce)(Ti,Fe,Cr,Mg)21O38. It is a late-stage magmatic mineral, formed in the residual melt of mafic layered intrusions in either the olivine-chromite, pyroxene, or plagioclase-rich layers.

Discovery and occurrence Loveringite was discovered in 1978 in the Jimberlana Intrusion, Dundas Shire, Western Australia, and was named for Australian geochemist and University of Melbourne professor John Francis Lovering, in recognition of his work on fission-track methods in geochemistry. Loveringite has also been generally found in areas of medium-grade metamorphism, reported from the Hoggar Mountains of Algeria; the Hohe Tauern Mountains, Salzburg, Austria; the Koitelainen intrusion of Lappland, Finland; Bourg d’Oisans, Isere, France; Bracco, Liguria, Italy; the Kerguelen Islands; the Khibiny Massif in the Kola Peninsula of Russia; and at Makwiro on the Great Dyke in Zimbabwe.

Crystallography Loveringite is trigonal (crystal system), rhombohedral (crystal class), meaning it contains three equal axes each related by 120° and one axis perpendicular to these. It has a three-fold rotation axis as well as a center of symmetry and belongs to the space group R3. Loveringite is found to be grayish white to gray in plane polarized light and does not display pleochroism. Additionally, when viewed in plane polarized light, Loveringite is found to have high relief and has sharp grain boundaries, shows fractures and cleavages well, and sticks out above other minerals in the thin section. Reflectance data indicates that loveringite is anisotropic, showing properties of different values when measured in different directions.

Worked examples

Example 1 — a first encounter with Loveringite

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

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

Why does Loveringite 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 Loveringite?

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.
