This map illustrates the distribution of thorium reserves across India, highlighting key states with varying concentration levels. Darker shades represent higher reserve percentages, while lighter tones indicate smaller deposits. Major thorium-bearing regions appear along the eastern and southern coasts, particularly in Andhra Pradesh, Odisha, Tamil Nadu, and Kerala. Inland deposits are also marked in Telangana and the Ranchi Plateau area of Jharkhand. Important locations such as Chhatrapur and Manavalakurichi are labeled to show significant thorium-bearing mineral sands.
Thorium resources in India are largely associated with coastal placer deposits rich in monazite sands. These reserves are strategically important for India’s long-term nuclear energy program. The map provides a clear visual comparison of regional distribution using percentage ranges from 0–5% to 35%. This makes it useful for educational reference, resource planning, and geographic analysis.
