Gondwanaland and the Gondwana Rock System: India’s Coal Backbone

A single rock formation supplies most of India’s coal. This article covers the Gondwana system, and the ancient supercontinent it’s named after.

Must Know

• Gondwanaland was an ancient supercontinent. It once joined present-day India, Africa, South America, Australia and Antarctica together.
• The name comes from the Gond region of central India, in today’s Madhya Pradesh and Chhattisgarh.
• Geologist H.B. Medlicott applied the name “Gondwana System” to a distinctive rock sequence there, in the 1870s.
• Austrian geologist Eduard Suess later extended the name to the entire ancestral southern supercontinent.
• The Gondwana rock system formed during the Permian period, roughly 250-300 million years ago. It contains India’s major coal-bearing formations.

Good to Know

• Gondwana coalfields contribute about 98% of India’s total coal production, concentrated along the Damodar, Son, Mahanadi, Godavari and Wardha river valleys.
• The Damodar Valley alone hosts several distinct Gondwana formations: Karharbari, Barakar, Barren Measures, and Raniganj.
• The Barakar Formation is one of India’s most significant coal-bearing strata within this sequence.
• A uniform Glossopteris flora dominated the entire Gondwana supercontinent during the Permian period, evidence used to reconstruct the ancient landmass’s extent.

Great to Know

• Gondwanaland’s breakup, driven by plate tectonics, scattered its rock formations across today’s separate continents. The Gondwana rock system in India is one surviving piece of that original landmass.
• Naming the entire supercontinent after one Indian region shows how influential early Indian geological surveys were. British-era surveyors’ local findings shaped a globally used geological term.
• The Glossopteris fossil evidence is a key reason scientists accept continental drift. Finding the same plant fossils across now-separated continents only makes sense if those continents were once joined.
• Concentrating 98% of coal production in one rock system creates real economic dependence. Any disruption to Gondwana coalfield mining has an outsized effect on India’s energy supply.
