Khok Kruat Formation

Khok Kruat 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 Khok Kruat Formation rather than just read about it. In short: The Khok Kruat Formation (Thai: หมวดหินโคกกรวด) is a rock formation found in northeastern Thailand. It is the uppermost formation of the Khorat Group.

Key takeaways

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

Reference excerpt

The Khok Kruat Formation (Thai: หมวดหินโคกกรวด) is a rock formation found in northeastern Thailand. It is the uppermost formation of the Khorat Group. It is dated to the Aptian stage of the Early Cretaceous period, and is notable for its fossils of dinosaurs. It is equivalent to the Gres superieurs Formation of Laos. The group is a fluvial formation consisting primarily of red siltstones and sandstones.

Vertebrate paleofauna

The Khok Kruat Formation has yielded remains of sharks, fishes, turtles, crocodilians and pterosaurs. Phuwiangosaurus-like teeth, Siamosaurus teeth, and fragmentary postcranial remains of spinosaurids have also been recovered from it. Fukuiraptor-like teeth have also been recovered from the formation.

Worked examples

Example 1 — a first encounter with Khok Kruat Formation

Start with the simplest possible case. Write down what Khok Kruat 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 Khok Kruat 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 Khok Kruat 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 Khok Kruat Formation

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