Aravalli Range

  • Location: North-western of India, stretching from Delhi to Gujarat through Haryana and Rajasthan
  • Historical Significance: It stands as one of the oldest fold mountains globally, bearing witness to millions of years of Earth's history.
  • Length: 670 km 
  • Formation: Its formation is deeply rooted in the collision of tectonic plates during the Proterozoic era, shaping the landscape we see today.
  • Geological Context: As part of the Indian Shield, it represents a significant geological formation formed through ancient cratonic collisions.
  • Highest Peak: Guru Shikhar Peak (1722m) on Mount Abu.
  • Rivers: Major rivers like Banas, Sahibi, and Luni originate from the Aravalli, contributing to the rich hydrology of the region and its surrounding areas.
  • Erosional History: Despite once towering to great heights, the Aravalli has weathered over millions of years, attesting to the relentless forces of erosion.
  • Minerals: The range boasts abundant mineral resources like copper, zinc, lead, and marble, contributing to economic activities and historical significance.
  • Division: It can be classified into two main sections: the Sambhar-Sirohi ranges, featuring notable peaks like Guru Shikhar, and the Sambhar-Khetri ranges, characterized by discontinuous ridges.
