Suining Formation

Suining 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 Suining Formation rather than just read about it. In short: The Suining Formation (simplified Chinese: 遂宁组; traditional Chinese: 遂寧組; pinyin: Suìníng Zǔ) is a geological formation in China whose strata likely date back to the Late Jurassic. Dinosaur remains are among the fossils that have been recovered from the formation.

Key takeaways

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

Reference excerpt

The Suining Formation (simplified Chinese: 遂宁组; traditional Chinese: 遂寧組; pinyin: Suìníng Zǔ) is a geological formation in China whose strata likely date back to the Late Jurassic. Dinosaur remains are among the fossils that have been recovered from the formation.

History The Suining Formation was identified in 1939. The formation was initially dated to the Tithonian (Late Jurassic). A 2019 publication described zircons from the Suining Formation that implied a younger age, the average age being around 115.5–113.3 million years ago (Early Cretaceous, upper Aptian age). Later research suggested that a Late Jurassic age is more likely based on reinterpretations of the previous zircon-based ages and comparisons of the dinosaur and pollen fossils with other more confidently-dated formations.

Worked examples

Example 1 — a first encounter with Suining Formation

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

In research: Suining 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 Suining 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: Suining Formation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chinese geologic formation stubs, Cretaceous China, Geologic formations of China, so understanding it makes those chapters shorter.
In everyday life: Look for Suining 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.

Frequently asked questions

What is Suining Formation in simple terms?

Why does Suining Formation matter?

Because it connects several earth science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Suining Formation?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
