Subashi Formation

Subashi 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 Subashi Formation rather than just read about it. In short: The Subashi Formation (Chinese: 苏巴什组) is a Late Cretaceous (Campanian to Maastrichtian) formation from the Xinjiang Autonomous Region of western China. Initially described by Dong Zhiming in 1977, the formation contains remains of Tarbosaurus which were initially described as a separate taxon Shanshanosaurus huoyanshanensis.

Key takeaways

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

Reference excerpt

The Subashi Formation (Chinese: 苏巴什组) is a Late Cretaceous (Campanian to Maastrichtian) formation from the Xinjiang Autonomous Region of western China. Initially described by Dong Zhiming in 1977, the formation contains remains of Tarbosaurus which were initially described as a separate taxon Shanshanosaurus huoyanshanensis. Remains of a sauropod, likely Nemegtosaurus, and a hadrosaurid, likely Jaxartosaurus, have also been found. The formation is located in the Flaming Mountains region of Xinjiang, north of the Turpan Depression. It is not far from Lianmuqin Town of Shanshan County, and is presumably named after the village of Subashi (42°55′11″N 89°44′36″E), which is located some 15 kilometres (9.3 mi) to the west of Lianmuqin, in Tuyugou Township (吐峪沟乡).

Fossil content The following fossils were reported from the formation:

Dinosaurs

Ornithischians

Sauropods

Theropods

Turtles

Oofossils

Worked examples

Example 1 — a first encounter with Subashi Formation

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

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