Tabataud Quarry

Tabataud Quarry 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 Tabataud Quarry rather than just read about it. In short: The Tabataud Quarry (sometimes also written Tabateaud) is situated in the northwestern French Massif Central. The quarry used to be mined for its granodiorite.

Key takeaways

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

Reference excerpt

The Tabataud Quarry (sometimes also written Tabateaud) is situated in the northwestern French Massif Central. The quarry used to be mined for its granodiorite.

Geography

The Tabataud Quarry was excavated along the left bank of the river Bandiat at an elevation of 165 metres, only about one kilometer southeast of Nontron town centre. Nearby passes the D 707 from Nontron to Saint-Pardoux-la-Rivière, from which it is easily accessible. In the immediate vicinity are two more adjoining quarries, the Maspeyrot-Lagarde quarry and the Moulin Blanc quarry, which are both older. All these quarries are closed by now and they are dangerous due to rockfall.

Geology The Tabataud quarry and its two satellites were worked from the Piégut-Pluviers Granodiorite, more precisely from its dark, fine-grained, biotite- and amphibole-bearing (green hornblende) border facies. Because of its slight blueish hue the rock used to be called granite bleu (blue granite) by the local population. Along the west side of the quarry crosses a NNE-SSW-striking fault zone that sets off the granodiorite from the plagioclase-bearing paragneisses farther west (Nontron Paragneiss). Within the quarry the granodiorite is traversed by a stockwork of mineralized dikes. Altogether 17 southeast-northwest-striking lodes are encountered. They only reach thicknesses of about 3 centimeters, an exception being the Puyssechet lode near the Moulin Blanc quarry, which is 30 cm thick and strikes east-west. Besides the lodes there are also some pegmatite dikes.

Mineralogy

The encountered lodes in the quarry belong to the classical sphalerite-pyrite-galena-chalcopyrite ore mineral association. As in the nearby Cantonnier Lode the mineralizations formed hydrothermally.

History Quarrying started in the Tabataud quarry in the 1890s. The encountered ores were gathered, but the focus of the mining activities was the granodiorite itself. In the beginning the granodiorite was a highly esteemed building and cobble stone, but was milled later on mainly to gravel (for roadworks etc.). In 2003 the mining came to a final halt; since then the quarry has been used as a storage area for the countless trees uprooted by cyclone Lothar in 1999. It is flooded by now.

Worked examples

Example 1 — a first encounter with Tabataud Quarry

Start with the simplest possible case. Write down what Tabataud Quarry 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 Tabataud Quarry 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 Tabataud Quarry 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 Tabataud Quarry

In research: Tabataud Quarry 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 Tabataud Quarry 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: Tabataud Quarry is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures in Dordogne, Geography of Dordogne, Geology of France, so understanding it makes those chapters shorter.
In everyday life: Look for Tabataud Quarry 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.
