Khilok Formation

Khilok 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 Khilok Formation rather than just read about it. In short: The Khilok Formation is an Early Cretaceous geologic formation in Buryatia, Russia. While the lower portion of the formation consists of sandstone and conglomerates, the upper portion of the formation largely consists of trachybasalt, these deposits have been dated to the Aptian.

Key takeaways

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

Reference excerpt

The Khilok Formation is an Early Cretaceous geologic formation in Buryatia, Russia. While the lower portion of the formation consists of sandstone and conglomerates, the upper portion of the formation largely consists of trachybasalt, these deposits have been dated to the Aptian. A thin 20 cm bed is known from the formation containing the remains of numerous indeterminate vertebrates, including dinosaur and pterosaurs and an indeterminate species of Kirgizemys.

Fossil content The following fossils were reported from the formation:

Reptiles Kirgizemys sp. Prodeinodon sp. Choristodera indet. Dromaeosauridae indet. Hypsilophodontidae indet. Ornithopoda indet. Ornithocheiridae indet. Scincomorpha indet. Testudines indet. Titanosauriformes indet. Amphibians Discoglossidae indet. Fish Hybodus sp. Amiiformes indet. Palaeonisciformes indet. Teleostei indet.

Worked examples

Example 1 — a first encounter with Khilok Formation

Start with the simplest possible case. Write down what Khilok 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 Khilok 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 Khilok 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 Khilok Formation

In research: Khilok 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 Khilok 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: Khilok Formation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aptian Stage, Conglomerate formations, Cretaceous Russia, so understanding it makes those chapters shorter.
In everyday life: Look for Khilok 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.
