Slyne-Erris Basin

Slyne-Erris Basin 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 Slyne-Erris Basin rather than just read about it. In short: The Slyne-Erris Basin or Slyne-Erris Trough' is a geological basin off the west coast of Donegal, Ireland. In recent years it has been shown to be prospective for hydrocarbons, hosting Royal Dutch Shell Corrib gas field (discovered by Enterprise Oil, bought by Shell), and several other prospects being evaluated by a number of other oil companies.

Key takeaways

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

Reference excerpt

The Slyne-Erris Basin or Slyne-Erris Trough' is a geological basin off the west coast of Donegal, Ireland. In recent years it has been shown to be prospective for hydrocarbons, hosting Royal Dutch Shell Corrib gas field (discovered by Enterprise Oil, bought by Shell), and several other prospects being evaluated by a number of other oil companies. Structurally, the basin is a series of NNE-SSW trending half-grabens.

The Slyne Basin The Slyne Basin or Slyne Trough consists of three sub-basins, the Northern, Central and Southern Slyne Basins. The Northern and Central Slyne Basins are half-grabens of opposite polarity with the switch occurring across the Central Slyne Transfer, interpreted to be a splay of the Great Glen Fault. The Corrib Field is situated in the Northern Slyne Basin. In the Central Slyne the 27/5-1 well proved the presence of Late Permian evaporites including salt, possibly indicating fault activity at this time. The basin is interpreted to have been active particularly during the Triassic and Middle Jurassic periods. The Slyne Basin links the Erris and Porcupine Basins.

The Erris Basin The Erris Basin or Erris Trough is a half-graben that runs parallel with the Rockall Basin and is separated from it by a horst structure, the Erris Ridge. It is interpreted to have been active particularly during the Permian to Triassic and middle Jurassic periods.

Worked examples

Example 1 — a first encounter with Slyne-Erris Basin

Start with the simplest possible case. Write down what Slyne-Erris Basin 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 Slyne-Erris Basin 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 Slyne-Erris Basin 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 Slyne-Erris Basin

In research: Slyne-Erris Basin 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 Slyne-Erris Basin 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: Slyne-Erris Basin is common in secondary-school and first-year university syllabi. It links to neighbouring topics Economic geology, Geography of Ireland, Mesozoic rifts and grabens, so understanding it makes those chapters shorter.
In everyday life: Look for Slyne-Erris Basin 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.
