The type of rocks in India that produces manganese is the Dharwar rocks.

Dharwar rocks are a type of geological formation found in India, primarily in the Dharwar region of Karnataka. These rocks are known for their rich mineral deposits, including manganese.

Formation of Dharwar rocks

Dharwar rocks are classified as Archean-age rocks, which means they were formed during the Archean Eon, approximately 4 to 2.5 billion years ago. These rocks were formed through various geological processes such as volcanism, sedimentation, and tectonic activity.

Composition and characteristics

Dharwar rocks are predominantly made up of granitic gneisses, schists, and greenstones. They also contain significant amounts of manganese-bearing minerals. Manganese is primarily found in the form of oxides and hydroxides within these rocks.

Manganese deposits in Dharwar rocks

The manganese deposits in Dharwar rocks are known for their economic significance. These deposits occur as stratabound ore bodies within the sedimentary and metavolcanic rocks of the Dharwar Supergroup. The ore bodies are often found in close association with iron and other mineral deposits.

Importance of manganese

Manganese is an essential element for various industrial applications. It is primarily used in the production of steel, where it acts as a deoxidizing and desulfurizing agent. Manganese is also used in the production of batteries, alloys, and fertilizers.

Conclusion

In conclusion, the type of rocks in India that produces manganese is the Dharwar rocks. These rocks, found in the Dharwar region of Karnataka, are known for their rich mineral deposits, including manganese. The manganese deposits occur as stratabound ore bodies within the sedimentary and metavolcanic rocks of the Dharwar Supergroup. Manganese is an important element used in various industrial applications, particularly in the production of steel.
