What is the main reason for the abundance of minerals in the Peninsular Plateau?

Answer and explanation

Correct answer: Ancient hard rock structure

Direct answer: Option A, ancient hard rock structure. The Peninsular Plateau is made largely of very old crystalline and metamorphic rocks. Geological processes associated with such rocks have concentrated many mineral resources, including iron ore, manganese, mica, and bauxite in different areas. Therefore the ancient rocky foundation is the main reason for mineral abundance. Option B is wrong because new alluvial deposits mainly characterize plains, not the ancient plateau core. Option C is wrong because marine salt layers do not explain the plateau’s broad mineral wealth. Option D is wrong because glacial ice is not the plateau’s basic structure. Cue: ancient rocks and minerals belong together.
