Lincolnshire Limestone Formation

Lincolnshire Limestone Formation 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 Lincolnshire Limestone Formation rather than just read about it. In short: The Lincolnshire Limestone Formation is a geological formation in England, part of the Inferior Oolite Group of the (Bajocian) Middle Jurassic strata of eastern England. It was formed around 170 million years ago, in a shallow, warm sea on the margin of the London Platform and has estuarine beds above and below it.

Key takeaways

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

Reference excerpt

The Lincolnshire Limestone Formation is a geological formation in England, part of the Inferior Oolite Group of the (Bajocian) Middle Jurassic strata of eastern England. It was formed around 170 million years ago, in a shallow, warm sea on the margin of the London Platform and has estuarine beds above and below it. There are two sub-divisions, the Upper and Lower Lincolnshire Limestone. It is typically about 30 m thick, reaching a maximum of over 40 m in south Lincolnshire. The lower division varies in thickness between 15 m and 21 m and the upper is typically between 10 m and 16 m thick. The dividing marker is the 'Crossi' bed which is distinguished by the fossils of the brachiopod Acanthothris crossi it contains. The Crossi bed forms the top of the Lower Lincolnshire limestone. The bottom of the Lower Lincolnshire limestone has some of the characteristics of the underlying Lower Estuarine Series, in that it tends to contain more than usual amounts of sand. A stone from this part of the formation which was commercially exploited is the Collyweston stone slate which was used for roofing for several centuries. It is now largely replaced in new work by concrete imitations. Much of the rest of the Lower Lincolnshire limestone is oolitic. It formed in warm, shallow seas where evaporation concentrated the dissolved calcium carbonate and then the precipitated material formed concentric layers building up around a nucleus of, usually, a shell fragment as the sea surface was disturbed by winds rolling the sea-bed material around: the resulting little rounded balls are called ooliths or ooids.

Worked examples

Example 1 — a first encounter with Lincolnshire Limestone Formation

Start with the simplest possible case. Write down what Lincolnshire Limestone Formation 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 Lincolnshire Limestone Formation 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 Lincolnshire Limestone Formation 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 Lincolnshire Limestone Formation

In research: Lincolnshire Limestone Formation 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 Lincolnshire Limestone Formation 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: Lincolnshire Limestone Formation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bajocian Stage, Geography of Lincolnshire, Geologic formations of the United Kingdom, so understanding it makes those chapters shorter.
In everyday life: Look for Lincolnshire Limestone Formation 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.
