Oldest Mountains in India: Aravallis

The Aravalli Range is a range of mountains in western India that runs approximately 800 km from northeastern Gujarat through Rajasthan to Haryana. It is the oldest mountain range in India, and one of the oldest mountain ranges in the world.

Geological History

The Aravalli Range was formed during the Proterozoic Era, which began about 2.5 billion years ago and ended about 541 million years ago. During this time, the Indian subcontinent was part of the supercontinent of Rodinia, which later broke apart into smaller landmasses.

The Aravalli Range was formed as a result of the collision of the Indian subcontinent with the Eurasian Plate. The collision caused intense volcanic activity and tectonic uplift, which led to the formation of the range.

The Aravalli Range is made up of rocks from the Aravalli Supergroup, which includes rocks that are 2.5 billion years old. These rocks include gneiss, schist, quartzite, and marble.

Importance

The Aravalli Range is an important geological feature in India. It is a major source of minerals such as copper, zinc, lead, and silver. The range also provides water to the surrounding region.

The Aravalli Range is also important from an ecological perspective. It is home to a diverse range of flora and fauna, including several endangered species. The range is also an important habitat for migratory birds.

Conclusion

In conclusion, the Aravalli Range is the oldest mountain range in India, and one of the oldest mountain ranges in the world. It was formed during the Proterozoic Era as a result of the collision of the Indian subcontinent with the Eurasian Plate. The range is important from both a geological and ecological perspective.
