Aravalli Range

The Aravalli Range is one of the oldest mountain ranges in the world and a vital natural feature of the Indian subcontinent. Stretching across several states in western and northern India, this ancient range has played a crucial role in shaping the region’s geography, climate, culture, and biodiversity. Despite its age and historical importance, the Aravalli Range often remains underappreciated compared to younger and more dramatic mountain systems like the Himalayas.

The origin, structure, ecological significance, cultural importance, and present-day challenges faced by the Aravalli Range. It also highlights why protecting this ancient mountain system is essential for environmental balance, water security, and sustainable development.

Overview of the Aravalli Range

The Aravalli Range is among the oldest folded mountain ranges in the world, with geological origins dating back nearly two billion years. It stretches approximately 800 kilometers, starting from Gujarat, passing through Rajasthan, and extending into Haryana and Delhi.

Unlike towering mountain systems, the Aravalli Range is characterized by worn-down hills, rocky ridges, and gentle slopes, shaped by millions of years of erosion.

Key Geographic Features

• Length: Around 800 km

• Direction: Southwest to northeast

• States covered: Gujarat, Rajasthan, Haryana, and Delhi

• Highest peak: Guru Shikhar (Mount Abu)

Geological History of the Aravalli Range

The Aravalli Range is older than the Himalayas and holds immense geological importance. It originated during the Proterozoic Eon, making it one of the earliest examples of mountain formation on Earth.

Formation Process

• Formed through tectonic plate movements

• Shaped by intense heat and pressure

• Composed mainly of metamorphic and igneous rocks

Over time, erosion flattened much of the range, giving it its present-day low elevation compared to younger mountain systems.

Geographic Spread and Landscape

The Aravalli Range passes through diverse landscapes, including deserts, plains, forests, and plateaus. This diversity makes it an ecological transition zone between arid and semi-arid regions.

Major Regions Covered

• Rajasthan: Largest portion, including Mount Abu

• Haryana: Acts as a natural barrier for the Indo-Gangetic plains

• Delhi: Forms the Delhi Ridge

• Gujarat: Southern extension of the range

Each region adds unique ecological and cultural value to the range.

Without the Aravalli Range, the Thar Desert could expand further eastward, affecting agriculture and human settlements.

Biodiversity of the Aravalli Range

Despite harsh climatic conditions, the Aravalli Range supports diverse flora and fauna. Its ecosystems include dry deciduous forests, thorn forests, and scrublands.

Flora

• Neem

• Dhau tree

• Banyan

• Peepal

• Khejri

Fauna

• Leopards

• Hyenas

• Jackals

• Nilgai

• Various bird and reptile species

The range acts as an important wildlife corridor connecting different habitats.
