Examine the mineral genesis and stratigraphy of the Dharwar rock system in India: Statement I: The Dharwar schist rocks are ancient metamorphic sedimentary formations that host the country's most valuable metallic mineral deposits, including iron ore, manganese, and gold. Statement II: These rock formations are extensively distributed across the Chota Nagpur Plateau, Singhbhum, and parts of the northern Odisha mineral belt. Which of the following is correct?

💡 Solution & Explanation

Both statements are correct because the Archaean Dharwar system represents the primary metallogenic province of India, containing rich iron and manganese ores in regions like Mayurbhanj, Keonjhar, and Sundargarh. Confusing Dharwar metallogeny with younger sedimentary basins can lead to errors in economic geology assessments. India's heavy manufacturing industry depends heavily on mineral extractions from these ancient cratonic formations.
