Shelburne dike

Shelburne dike 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 Shelburne dike rather than just read about it. In short: The Shelburne dike, also known as the Great Dike, is a large northeast-trending Mesozoic diabase dike in southwestern Nova Scotia, Canada. It is 140 km (87 mi) long, although some evidence suggests it extends a further 60 km (37 mi) to the northeast to Sambro Island.

Key takeaways

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

Reference excerpt

The Shelburne dike, also known as the Great Dike, is a large northeast-trending Mesozoic diabase dike in southwestern Nova Scotia, Canada. It is 140 km (87 mi) long, although some evidence suggests it extends a further 60 km (37 mi) to the northeast to Sambro Island. The dike may have fed volcanoes during the Triassic period when the landscape was rifting apart during the breakup of supercontinent Pangaea.

Worked examples

Example 1 — a first encounter with Shelburne dike

Start with the simplest possible case. Write down what Shelburne dike 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 Shelburne dike 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 Shelburne dike 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 Shelburne dike

In research: Shelburne dike 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 Shelburne dike 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: Shelburne dike is common in secondary-school and first-year university syllabi. It links to neighbouring topics Igneous petrology of Nova Scotia, Igneous petrology stubs, Magmatic dikes, so understanding it makes those chapters shorter.
In everyday life: Look for Shelburne dike 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.
