Iceland Plateau

Iceland Plateau 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 Iceland Plateau rather than just read about it. In short: The Iceland Plateau or Icelandic Plateau is an oceanic plateau in the North Atlantic Ocean consisting of Iceland and its contiguous shelf and marginal slopes. The landscape is constantly experiencing deformation due to the continual addition of magma to the surface and the shifting of the Mid-Atlantic Ridge.

Key takeaways

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

Reference excerpt

The Iceland Plateau or Icelandic Plateau is an oceanic plateau in the North Atlantic Ocean consisting of Iceland and its contiguous shelf and marginal slopes. The landscape is constantly experiencing deformation due to the continual addition of magma to the surface and the shifting of the Mid-Atlantic Ridge.

Location and characteristics The Iceland Plateau is bounded on the south by the Reykjanes Ridge, on the west by the Greenland-Iceland Ridge, on the north by the Kolbeinsey Ridge, and on the east by the Iceland-Faeroe Ridge. It consists of a large igneous province that has been volcanically active since at least the Miocene epoch. The plateau has an average elevation of 1,700 meters above sea level. The geology of the Icelandic Plateau consists of three layers, closely mimicking the structure of oceanic crust but with one key difference, the second layer of the oceanic crust does not contain piles of lava flow like the Icelandic Plateau does. The first layer is composed of mainly sedimentary rock, the second layer is piles of lava flows, and the third layer is a thick layer of gabbro.

Tectonics and geology The Icelandic Plateau began forming approximately 56 Ma, due to the opening of the North Atlantic. As the plates began to diverge from each other, piles of lava rose to the surface, creating the ridges present on the landscape currently. The plateau is an example of ridge-hotspot interaction. The plateau resides above a hot spot on an active rift zone of the Mid-Atlantic Ridge from which extensive tholeiitic plateau basalts and a number of large rhyolitic domes have been extruded. Today, there are two main parts of the island, one which is slanted towards the sea floor, and another at a level surface.

Worked examples

Example 1 — a first encounter with Iceland Plateau

Start with the simplest possible case. Write down what Iceland Plateau 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 Iceland Plateau 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 Iceland Plateau 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 Iceland Plateau

In research: Iceland Plateau 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 Iceland Plateau 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: Iceland Plateau is common in secondary-school and first-year university syllabi. It links to neighbouring topics Holocene volcanism, Hotspot volcanism, Large igneous provinces, so understanding it makes those chapters shorter.
In everyday life: Look for Iceland Plateau 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.
