Reference excerpt

Jodhpur Group-Malani Igneous Suite Contact of the Aravalli Range is a geological feature representing the last phase of igneous activity of the Precambrian age in the Indian subcontinent at the foot of the Mehrangarh Fort in Jodhpur district. The Geological Survey of India declared the site as a National Geological Monument in 1976.

Geography The Malani Igneous Suite covers about 44,500 km2 (17,200 sq mi) to the west of the Aravalli Range, extending across Western Rajasthan. At Jodhpur, it is exposed in contact with the sandstone of the Jodhpur Group at the foot of Mehrangarh Fort. The site was declared as a National Geological Monument by the Geological Survey of India in 1976.

Geology The lithological formations of Rajasthan consist of sedimentary rocks of the Vindhyan or Marwar Supergroups, comprising sandstone, limestone and shale, in the eastern part of the state. In western Rajasthan, the geological formations include igneous rocks such as granite bosses and sills, formed from thick accumulations of acidic lava produced by volcanic activity that preceded the deposition of the overlying sedimentary rocks. The Malani Igenous Suite is composed mainly of rhyolite. The Mehrangarh Fort stands on a rhyolite rock exposure forming a hillock about 120 m (390 ft) high. The Trans-Aravalli region has a geological setting distinct from the rest of Rajasthan. At Jodhpur, the Malani Igneous Suite is overlain by a thick sequence of undeformed sedimentary rocks of the Vindhyan and Marwar Supergroups, deposited during the late Proterozoic and early Cambrian, around 540 million years ago. At the Mehrangarh hill, the contact between the volcanic rocks below and the overlying sedimentary rocks is clearly exposed. This unconformity is important for understanding the age and relationship between the two rock groups as it represents the last major phase of Precambrian igneous activity in the Indian subcontinent. The Malani rocks at the site include purple, red and ash-coloured laminated tuffs, chocolate-coloured chalcedony, dark-red obsidian, and purple, reddish, buff, whitish and grey rhyolitic tuffs associated with ignimbrites. The colourful volcanic rocks contrast sharply with the light-coloured Jodhpur sandstone above them.

Worked examples

Example 1 — a first encounter with Jodhpur Group – Malani Igneous Suite Contact

Start with the simplest possible case. Write down what Jodhpur Group – Malani Igneous Suite Contact 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 Jodhpur Group – Malani Igneous Suite Contact 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 Jodhpur Group – Malani Igneous Suite Contact 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 Jodhpur Group – Malani Igneous Suite Contact

In research: Jodhpur Group – Malani Igneous Suite Contact 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 Jodhpur Group – Malani Igneous Suite Contact 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: Jodhpur Group – Malani Igneous Suite Contact is common in secondary-school and first-year university syllabi. It links to neighbouring topics Geology of Rajasthan, Jodhpur district, National Geological Monuments in India, so understanding it makes those chapters shorter.
In everyday life: Look for Jodhpur Group – Malani Igneous Suite Contact 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.
