Los Blanquitos Formation

Los Blanquitos 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 Los Blanquitos Formation rather than just read about it. In short: The Los Blanquitos Formation is a geological formation in Salta Province, Argentina whose strata date back to the late Campanian to early Maastrichtian age of the Late Cretaceous Period. Dinosaur remains are among the fossils that have been recovered from the formation.

Key takeaways

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

Reference excerpt

The Los Blanquitos Formation is a geological formation in Salta Province, Argentina whose strata date back to the late Campanian to early Maastrichtian age of the Late Cretaceous Period. Dinosaur remains are among the fossils that have been recovered from the formation. The formation consists of friable, micaceous, grayish-red sandstones with quartz pebbles containing small carbonate veins. In the base of this layer the remains of a titanosaurid dinosaur were discovered. Above the layer with bones appears a lens of thick, greenish-gray, calcareous, very hard sandstone with pebbles and gravel. The bones were covered by a "halo" of the same rock but of greenish or grayish color, especially visible because the normal sediment is red. The bed thickness is 1.5 metres (4.9 ft).

Vertebrate paleofauna Guemesia ochoai - an abelisaurid theropod dinosaur, known from a nearly complete braincase Unquillosaurus ceiballi - a theropod dinosaur (possibly carcharodontosaurian or Maniraptoran), known from a pubis ?Titanosaurus sp. - a sauropod dinosaur

Worked examples

Example 1 — a first encounter with Los Blanquitos Formation

Start with the simplest possible case. Write down what Los Blanquitos 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 Los Blanquitos 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 Los Blanquitos 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 Los Blanquitos Formation

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