Zazhoginskoye

Zazhoginskoye 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 Zazhoginskoye rather than just read about it. In short: The Zazhoginskoe field is one of the richest Russian field of shungite on the territory of the Republic of Karelia. General information The Zazhoginskoe field is one of the largest fields of shungite rocks in the world.

Key takeaways

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

Reference excerpt

The Zazhoginskoe field is one of the richest Russian field of shungite on the territory of the Republic of Karelia.

General information The Zazhoginskoe field is one of the largest fields of shungite rocks in the world. It is located on the outskirts of the village Tolvuya in Medvezhyegorsky District of Karelia, 1.7 km from the shore of Lake Onega, 5 km from a navigable bay. Shungite rocks were deposited around the northern part of Lake Onega and under the lake. The field consists of two: Zazhoginskoe and Maksovo. Developed areas of the field are located 2–3 km to the south of the village Tolvuya. The development of Zazhoginskoe field began in the early 1990s. The field has a size of 22 km x 11 km. On the territory of the deposit are located the village Tolvuya and several other villages, including abandoned. Layers of shungite rocks interspersed with tuffs, dolomite and siltstone. Within the Zazhoginskoe field are sills and dikes of metadiabases and metagabbro. Thickness of the sills is typically less than 50 m, but at the upper base sills reach thicknesses of over 150 m. In general, igneous rocks make up about 30% of the productive series. Rocks of the upper base felt weak regional metamorphism (initial stage greenschist facies). A significant part of the deposits developed with metasomatic replacement of primary minerals by carbonate, sericite, albite and quartz. Currently 25 deposits have been identified and explored in varying degrees, containing from 0.2 to 58.0 million tons of high-carbon shungite rocks.

Chemical composition of the ores Carbon - 30% Quartz - 45% Complex silicates (mica, chlorite) - 20% Sulfides - 3% Rocks within the Zazhoginskoe field are sufficiently stable in composition. The sum (C+SiO2) is in the range of 83 - 90%.

Economic evaluation of reserves Using the method of A. I. Nijinsky, the identified reserves are valued at around 1,241 million US dollars. According to geologists, there are good prospects for discovery of new fields in the Kondopozhsky District, where the transport infrastructure is well-developed, in contrast to the district of Zaonezhye. The only developer of Zazhoginskoe field is CDD Carbon-Shungite.

Worked examples

Example 1 — a first encounter with Zazhoginskoye

Start with the simplest possible case. Write down what Zazhoginskoye 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 Zazhoginskoye 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 Zazhoginskoye 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 Zazhoginskoye

In research: Zazhoginskoye 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 Zazhoginskoye 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: Zazhoginskoye is common in secondary-school and first-year university syllabi. It links to neighbouring topics Geology of Russia, Natural resources, so understanding it makes those chapters shorter.
In everyday life: Look for Zazhoginskoye 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.
