Quilon formation

Quilon 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 Quilon formation rather than just read about it. In short: The Quilon limestone formation is a geologic formation existing on the west coast of India. The Quilon formation, along with Warkalli formation represent sediments laid down in the Kerala basin that existed during Mio-pliocene times.

Key takeaways

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

Reference excerpt

The Quilon limestone formation is a geologic formation existing on the west coast of India. The Quilon formation, along with Warkalli formation represent sediments laid down in the Kerala basin that existed during Mio-pliocene times. The Quilon formation of the Miocene age is made up of limestone, and the Warkalli formation is made up of alternating beds of sand and shale exposed along the Varkala cliffs.

Details The facies of the fossiliferous Quilon Limestone in SW India is described for the first time in detail at the Padappakkara-type locality. It comprises at least 2 horizons of fossiliferous limestone with marine fauna. The lower limestone horizon is characterized by colonial corals, while the upper horizon represents a larger foraminiferal Pseudotaberina malabarica facies which is well developed at the type locality, the coastal cliffs of Ashtamudi Lake at Padappakkara in SW India. The age of the fossiliferous marl of the Quilon Formation is numerically constrained to between 17.08 and 17.13 with an error range of 0.22 Ma. The source of the lignite debris, noted for the first time in the Quilon beds, is postulated as an old unknown bed either underlying or having existed nearby, but later removed by erosion or diastrophism. The proximity of the source of the Quilon sediments is supported by the presence of graphite in the sediments. Quilon Formation represents a rich fossil seagrass community, with proximity to a coral reef and mangroves. A diverse bony fish assemblage with numerous new species are reported from the marls exposed at the Pozhikkara locality of the Quilon Formation. This Formation also seems to record climatic events like Middle Miocene Climatic Optimum and Monterey Carbon Excursion.

Worked examples

Example 1 — a first encounter with Quilon formation

Start with the simplest possible case. Write down what Quilon 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 Quilon 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 Quilon 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 Quilon formation

In research: Quilon 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 Quilon 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: Quilon formation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cenozoic India, Geologic formations of India, Kollam, so understanding it makes those chapters shorter.
In everyday life: Look for Quilon 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 Quilon formation in simple terms?

Why does Quilon 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 Quilon 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.
