Mount Leura

Mount Leura 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 Mount Leura rather than just read about it. In short: Mount Leura is a 313-metre scoria cone surrounding a dry crater 100 m deep and is the central and most obvious component of a larger volcanic complex southeast of the town of Camperdown located in western Victoria, Australia, 194 kilometres (121 mi) south west of the state capital, Melbourne. The inactive volcano is thought to have last erupted between 5,000 and 20,000 years ago.

Key takeaways

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

Reference excerpt

Mount Leura is a 313-metre scoria cone surrounding a dry crater 100 m deep and is the central and most obvious component of a larger volcanic complex southeast of the town of Camperdown located in western Victoria, Australia, 194 kilometres (121 mi) south west of the state capital, Melbourne. The inactive volcano is thought to have last erupted between 5,000 and 20,000 years ago. The name means "big nose" in the local Aboriginal dialect.

Leura Maar Mount Leura, together with nearby Mount Sugarloaf, forms part of a large extinct volcanic complex known as the "Leura Maar". The complex includes a broad shallow maar crater measuring 2.5 km by 1.7 km surrounded by a low tuff ring, inside which are the secondary eruption points of Mount Leura and several smaller unnamed mounds and cones of scoria. These may represent eruptions along a north–south fissure. The walls of the cone are alternating layers of tuff and scoria with numerous blocks and volcanic bombs. Mount Sugarloaf is a perfect conical mound on the southwestern flank of Mount Leura and represents a final stage of activity of the Leura volcano, when a small vent ejected a large volume of lava fragments in a short time, without a change in the direction of the eruption column. This produced a steep, symmetrical, conical mound of volcanic ash, scoria and larger blocks and bombs.

Mining Numerous quarries operated within the "Leura Maar". Quarries also provide significant exposures of bedding in tuff and scoria and many xenoliths are obtained from these. The scoria at Mount Leura is notable for the inclusions of high temperature megacrusts and xenoliths (fragments of the lower crust and mantle of the earth) which occur here in unusually high concentrations. Most of the quarries now are closed and some are used for dumping landfill.

Tourism The volcano lies within the "Lakes and Craters" region, an access road was built in 1932. It allows vehicles the size of buses to access the lookout on top of Mount Leura. On a clear day you can see the Grampians and Mount Buninyong to the north, Mount Porndon to the east and Lavers Hill to the south. To the immediate west are the deep volcanic crater lakes Bullen-Merri and Gnotuk while to the east is the crater Lake Purrumbete popular for its trout and Chinook salmon fishing.

Hillclimb Mount Leura has hosted the Australian Hillclimb Championship twice, 1985 and 1997. The access road to the summit is closed for the competition. The Australian Hillclimb Championship has been sanctioned by the Confederation of Australian Motor Sport since 1954. Prior to this it was sanctioned by the Australian Automobile Association, with two events having national championship status in 1949.

Worked examples

Example 1 — a first encounter with Mount Leura

Start with the simplest possible case. Write down what Mount Leura 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 Mount Leura 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 Mount Leura 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 Mount Leura

In research: Mount Leura 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 Mount Leura 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: Mount Leura is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cinder cones, Inactive volcanoes, Maars of Australia, so understanding it makes those chapters shorter.
In everyday life: Look for Mount Leura 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.
