Introduction
Maharashtra, one of India’s most industrialized states, is home to a variety of mineral resources. Although it constitutes only 4.3% of India’s total mineral wealth, the state plays a crucial role in India’s iron ore, bauxite, manganese, limestone, chromite, and coal production.
The geological structure of Maharashtra includes Archaean, Gondwana, and Dharwar rock formations, which harbor valuable mineral deposits. The minerals extracted from these regions support industries such as steel, cement, power generation, chemicals, and metallurgy.
For MPSC aspirants, understanding the distribution, economic significance, and industrial applications of minerals in Maharashtra is vital for Geography, Economy, and General Knowledge sections of the exam.
This blog provides an in-depth analysis of Maharashtra’s mineral wealth, covering key mining districts, major minerals, their applications, and industrial impact.
