What geological importance do Dharwar and Singhbhum regions have in Peninsular India?
Answer and explanation
Correct answer: They represent old rocky and mineral-rich terrains
The governing concept is the geological antiquity of the Peninsular Plateau. Dharwar and Singhbhum are among India’s important ancient shield regions, composed largely of very old crystalline rocks formed during early stages of the earth’s geological history. These rocks have undergone prolonged weathering, deformation, and mineralization, so the regions are important for iron ore, gold, manganese, copper, and other mineral resources. Therefore, option A is correct. Coral islands in option B are young marine landforms, while the Ganga alluvial plains in option C are much younger depositional surfaces. Option D refers to the outer Himalayas, a younger mountain system with a different geological origin. Ancient rocks and mineral wealth are the key clues.
