Aravalli Mountain Range: Formation, Location, Minerals & Importance in India

The Aravalli Mountain Range is one of the most important physical features of Indian geography. It holds a unique position due to its great age, long geological history, and strong influence on climate, environment, and human settlement. This mountain range has shaped the landscape of north-western India for millions of years. Even today, it continues to play a vital role in maintaining ecological balance and supporting natural resources.

What is the Aravalli Mountain Range?

The Aravalli Range is among the oldest mountain systems in the world. It is far older than the Himalayas. Due to this reason, it is often described as a fossil or remnant mountain range. Over a long period of time, natural forces like wind, rain, and temperature changes have reduced its height.

This mountain range runs across the north-western part of India. It has influenced rivers, forests, climate, agriculture, and settlement patterns. Its importance is not limited to geography alone. It also has cultural, economic, and environmental significance.

Aravalli Mountain Geographical Location and Extent

The Aravalli Range is located in the north-western part of India and extends diagonally across several states.

States Covered

• Gujarat

• Rajasthan

• Haryana

• Delhi

Key Location Features

• Direction: Southwest to Northeast

• Major share lies in Rajasthan

• Forms a natural boundary near the Thar Desert

This location gives the range an important role in protecting fertile plains.

Formation of the Aravalli Mountains

The formation of the Aravalli Mountain Range is linked to plate tectonic movements. Around 570 million years ago, the Aravalli Plate collided with the Singhbhum Plate. This collision resulted in folding and uplift of the Earth’s crust.

This process led to the creation of a long mountain chain. At that time, the mountains were very high. Over millions of years, erosion reduced their height. Continuous weathering turned them into low hills and ridges.

Because of this long erosion history, the Aravalli range is now considered one of the oldest fold mountain ranges in India.

Important Hills and Peaks

Several hills and peaks are part of the Aravalli Mountain Range. These include Mount Abu, Achalgarh, Jarga Hill, Sher Hill, and Rishikesh Hill. Among them, Guru Shikhar is the highest point.

Mount Abu is the only hill station in Rajasthan. It is known for its cooler climate and forest cover. Many historical and religious sites are located in this region.

These hills add to the geographical and cultural value of the range.

Mineral Resources of the Aravalli Region

The Aravalli Mountain Range is rich in mineral resources. These minerals have supported mining activities for a long time. The region provides raw materials for various industries.

Important minerals found in this range include copper, zinc, lead, silver, and gold. High-quality marble is also obtained from this region. Marble from Rajasthan is widely used in construction and art.

These mineral resources contribute to economic activities and provide employment opportunities. However, mining needs careful regulation to protect the environment.

Rivers Originating from the Aravalli Range

The Aravalli Mountain Range is the source of several rivers that support nearby regions.

Cultural and Historical Importance

The Aravalli Mountain Range holds great cultural and historical value. Many ancient forts, temples, and settlements are located in this region. Cities like Udaipur and Chittorgarh developed near the foothills.

The Dilwara Jain Temples at Mount Abu are famous for their architecture and craftsmanship. These sites reflect the long human association with the range.

The hills also provided natural defense in earlier times. Many forts were built on elevated locations for protection.

Environmental Role of the Aravalli Range

The Aravalli Mountain Range plays a major role in maintaining ecological balance.

Environmental Functions

• Blocks hot desert winds

• Reduces the spread of desertification

• Limits dust storms

Climate Influence

• Affects monsoon wind movement

• Helps retain moisture

• Supports rainfall in nearby regions

This role is vital for agriculture and water security.

Biodiversity and Wildlife

The Aravalli Hills support diverse plant and animal life. Forests in this region provide habitat to many species. Wildlife sanctuaries and national parks are part of this ecosystem.

Key Protected Areas

• Sariska National Park

• Ranthambore National Park

These protected areas support wildlife conservation and ecological balance. The forests also help in soil conservation and groundwater recharge.

Present Status and Legal Concerns

In recent times, parts of the Aravalli Hills have faced challenges due to reduced protection. Certain hills and areas are no longer classified as protected zones.

This change may allow increased mining and construction activities. If not managed properly, this can lead to environmental damage. The fragile nature of the range makes it vulnerable to destruction. Loss of forest cover and hills can weaken the natural barrier against desert winds and climate change.

Importance of Conservation

Protecting the Aravalli Hills is essential for environmental stability. Conservation efforts can help in preserving forests, wildlife, and water resources.

Sustainable development practices are needed in this region. Mining and industrial activities should follow strict environmental guidelines.

Public awareness plays a key role in conservation. Understanding the importance of this ancient mountain range can support long-term protection efforts.

The Aravalli Range is a vital part of Indian geography. Its ancient origin, unique structure, mineral wealth, and environmental role make it highly significant. Though its height has reduced over millions of years, its importance remains strong.

This mountain range supports rivers, forests, wildlife, and agriculture. It also protects fertile lands from desertification and climate extremes. Preserving this range is necessary for ecological balance and future generations.

Understanding the Aravalli Range helps in appreciating its role in shaping India’s natural and human landscape.
