Kola Alkaline Province

Kola Alkaline Province 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 Kola Alkaline Province rather than just read about it. In short: The Kola Alkaline Province or Kola Alkaline Carbonatite Province is a discontiguous group of unusual igneous rocks centered in the Kola Peninsula of Russia and with outliers in nearby areas of Finland and in Arkhangelsk Oblast across the White Sea. The province is made up of alkaline-ultramafic rock complexes often associated to carbonatites and stand-alone dykes and pipes made up of carbonatites, kimberlites and si…

Key takeaways

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

Reference excerpt

The Kola Alkaline Province or Kola Alkaline Carbonatite Province is a discontiguous group of unusual igneous rocks centered in the Kola Peninsula of Russia and with outliers in nearby areas of Finland and in Arkhangelsk Oblast across the White Sea. The province is made up of alkaline-ultramafic rock complexes often associated to carbonatites and stand-alone dykes and pipes made up of carbonatites, kimberlites and similar rocks. To this it adds the large nepheline syenite bodies of the Lovozero Massif and the Khibiny Mountains. An estimate puts the total volume of the rocks of the Kola Alkaline Province at 15,000 ±2,700 km3. The more mafic silicate rocks of the province originated from small degrees of partial melting in a source region in Earth's mantle made up of garnet-bearing peridotite. The lithosphere had thicknesses similar to present-day (200 km) conditions when magmas originated in the Devonian. Prior to Devonian magmatism the Kola and Karelia region had experienced a long history of low-frequency alkaline and carbonatite volcanism. The Permian rocks of the Kola Alkaline Province is commonly presumed to represent an igneous hotspot created by a mantle plume. The relation of Kola Alkaline Province to other igneous or tectonic features is not clear. Some have suggested a link to the Permian Dnieper-Donets Rift while others have considered it as part of a much larger a "North Atlantic Alkaline Province".

Worked examples

Example 1 — a first encounter with Kola Alkaline Province

Start with the simplest possible case. Write down what Kola Alkaline Province 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 Kola Alkaline Province 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 Kola Alkaline Province 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 Kola Alkaline Province

In research: Kola Alkaline Province 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 Kola Alkaline Province 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: Kola Alkaline Province is common in secondary-school and first-year university syllabi. It links to neighbouring topics Carbonatite occurrences, Geography of Arkhangelsk Oblast, Geography of Kainuu, so understanding it makes those chapters shorter.
In everyday life: Look for Kola Alkaline Province 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.
