The Geology of the Western Ghats: Volcanic Origins and Biodiversity Hotspots

The Western Ghats are a mountain range along the western coast of India. They are known for their unique geology and rich biodiversity. The range has a complex geological history that dates back millions of years. Understanding its origins helps explain the region’s ecological significance.

Geological Formation

The Western Ghats primarily originated from volcanic activity during the Deccan Traps period around 66 million years ago. These volcanic eruptions created extensive basalt plateaus that form the core of the mountain range. Over time, erosion and tectonic movements shaped the current landscape.

Biodiversity Hotspots

The Western Ghats are designated as a UNESCO World Heritage Site due to their rich biodiversity. They host numerous endemic species of plants, animals, and insects. The region’s varied climate and topography create ideal conditions for diverse ecosystems.

Major Geological Features

The range features several notable geological formations, including:

  • Basalt plateaus
  • Deep river valleys
  • Waterfalls and escarpments
  • Rich mineral deposits
