Lohan Cura Formation

Lohan Cura 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 Lohan Cura Formation rather than just read about it. In short: The Lohan Cura Formation is a geologic formation with outcrops in the Argentine provinces of Río Negro, Neuquén, and Mendoza. It is the second oldest Cretaceous terrestrial formation in the Neuquén Basin.

Key takeaways

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

Reference excerpt

The Lohan Cura Formation is a geologic formation with outcrops in the Argentine provinces of Río Negro, Neuquén, and Mendoza. It is the second oldest Cretaceous terrestrial formation in the Neuquén Basin. The Lohan Cura Formation unconformably overlies the terrestrial La Amarga Formation. In some places it also overlies the older marine Agrio and Bajada Colorada Formations of the Mendoza Group through the same Middle Miranican unconformity. It is in turn overlain by the Candeleros Formation of the Neuquén Group, separated by the Main Miranican unconformity. The Lohan Cura correlates with the Rayoso Formation in some areas.

Subdivision The Lohan Cura Formation contains two members of roughly equal thickness. The lowermost member, Puesto Quiroga Member is approximately 85 metres (279 ft) thick. The lowest sediments in this unit are conglomerates, overlain by sandstones and siltstones. The upper two-thirds of the member consists mainly of shales. The Cullín Grande Member is the upper member within the formation, about 92 metres (302 ft) thick, which contains numerous sandstones displaying evidence of stream channels. Near the top of the sequence, siltstones and claystones become dominant.

Worked examples

Example 1 — a first encounter with Lohan Cura Formation

Start with the simplest possible case. Write down what Lohan Cura 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 Lohan Cura 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 Lohan Cura 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 Lohan Cura Formation

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