Headington stone 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 Headington stone rather than just read about it. In short: Headington stone is a limestone from the Headington Quarry area of Oxford, England. Geology Around 160 million years ago, during the Late Jurassic period, Britain was located further south and was submerged beneath a subtropical sea.

Key takeaways

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

Reference excerpt

Headington stone is a limestone from the Headington Quarry area of Oxford, England.

Geology Around 160 million years ago, during the Late Jurassic period, Britain was located further south and was submerged beneath a subtropical sea. The warm conditions meant that coral reefs could flourish. When the coral died, it was buried under successive layers of sediment and other debris. After millions of years, this became fossilized. It formed the Corallian Limestone that is now beneath the Headington Quarry area of Oxford.

Quarrying Historically, there were a number of stone quarries in Headington Quarry. Headington stone was traditionally used for a number of the older Oxford University college buildings. In 1396, stone from quarrying in Headington was used to build the bell-tower for New College. It was also used for Oxford's city walls. Headington stone was used in the 1520s by Cardinal Wolsey to build his Cardinal College, now known as Christ Church. Headington stone was particularly good for building since it can be cut in any direction and thus carved relatively easily. The stone was employed in buildings outside Oxford such as for Eton College and Windsor Castle. Later stone extracted from the quarry was of less good quality, for example, that used to build the lower part of the Radcliffe Camera. The stone was prone to erosion by pollution.

Literature The use of Headington stone in Oxford University buildings was mentioned by John Betjeman (1906–1984) in his poetry:

Friend of my youth, you are dead! and the long peal pours from the steeple Over this sunlit quad in our University city And soaks in Headington stone

Worked examples

Example 1 — a first encounter with Headington stone

Start with the simplest possible case. Write down what Headington stone 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 Headington stone 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 Headington stone 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 Headington stone

In research: Headington stone 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 Headington stone 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: Headington stone is common in secondary-school and first-year university syllabi. It links to neighbouring topics Building stone, Geologic formations of the United Kingdom, Geology of Oxfordshire, so understanding it makes those chapters shorter.
In everyday life: Look for Headington stone 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.
