Indian scientists have found new proof of ancient Gondwana wildfires in coal rocks. The study shows how old fires shaped forests, climate and coal-rich areas.
New Delhi (ABC Live): Indian scientists have found new proof of ancient Gondwana wildfires. These fires burned through old forests nearly 250 million years ago.
This finding matters because fire was a strong force in Earth’s past. It changed forests, land systems and coal-rich areas.
Moreover, the study shows that coal rocks are not only fuel sources. They are also records of Earth’s old climate. Therefore, Indian coal basins can help scientists study past fires, forests and climate change.
What Scientists Found
A team from the Birbal Sahni Institute of Palaeosciences (BSIP) studied coal-bearing rocks from the Godavari Valley Coalfield in India.
The team included Neha Aggarwal, Shivalee Srivastava and Runcie Paul Mathews. Their study appeared in Geological Journal (Wiley).
The team used three main methods:
| Method | Simple Meaning | Why It Helps |
|---|---|---|
| Palynofacies study | Study of tiny old plant matter in rocks | Helps find fire marks |
| Raman test | Study of carbon structure | Shows signs of burning |
| FTIR test | Study of chemical groups | Shows heat-linked change |
As a result, the team could tell real fire-made charcoal from other dark plant matter with more care.
The Earlier Problem
Earlier studies in Indian Permian rocks found large charcoal pieces. These findings gave the first clear signs of old fires.
However, scientists also needed to study much smaller charcoal pieces. These tiny pieces are called microcharcoal.
This created a problem. Many dark particles look the same under a microscope. Some come from fire. Others come from slow decay or air-based change.
Therefore, scientists needed a better way to tell them apart.
Why Old Methods Were Not Enough
Earlier research mostly depended on what scientists could see. That method helped, but it also caused doubt.
The main problem was the difference between two dark particles:
| Particle Type | Simple Meaning | Problem |
|---|---|---|
| OX-CH | Dark plant matter changed by air | It may look like charcoal |
| PAL-CH | Dark plant matter changed by fire | It points to old fire |
Because both can look alike, visual study alone could not always prove fire. Therefore, the new study used both visual checks and lab tests.
How the New Study Helped
The BSIP team used more than one method. First, they studied the shape and look of the particles. Then, they checked their carbon and chemical signs.
This gave stronger proof. It also reduced doubt in reading old fire records.
In simple words, the team did not depend only on appearance. Instead, it checked what the particles were made of.
Two Types of Fire Marks
The study found two kinds of fire-made microcharcoal.
Strong Fire Charcoal
Some charcoal particles showed strong signs of burning. These particles suggest hotter fires.
They also showed better carbon order. Therefore, they point to deeper heat change in plant matter.
Mild Fire Charcoal
Some charcoal particles showed lighter signs of burning. However, they still carried clear fire marks.
This matters because ancient fires did not all burn in the same way. Some were strong. Others were mild. Together, they show that Gondwana forests faced different kinds of fire.
What Raman Testing Showed
Raman testing helped scientists study carbon inside the particles.
The test showed signs linked with burning and heat. These signs helped prove that many particles were not just dark plant pieces.
Instead, fire had changed them.
What FTIR Testing Showed
FTIR testing gave more proof. It showed chemical signs linked with heat change.
Fire changes plant matter. Therefore, FTIR helped confirm that the particles had faced heat.
When visual study, Raman testing and FTIR testing pointed in the same direction, the proof became stronger.
Why This Matters for Climate Study
Ancient Gondwana wildfires matter because fire affects carbon, plants and land.
In the Permian age, fires may have changed how plant matter collected in wet areas. Over time, this plant matter helped form coal.
Moreover, old fire records help scientists build better climate models. Modern climate records are short. Therefore, scientists need old rocks to understand Earth’s long climate story.
Indian Coal Basins as Climate Records
The Godavari Valley Coalfield is not only a coal area. It is also a record of old climate and old life.
This matters for India. Coalfields are usually discussed only as mining and fuel zones. However, this study shows another side.
Indian coal basins can help the world study old forests, old fires and past climate stress.
Link With Modern Coal Climate Risks
This study also connects with ABC Live’s earlier report on methane monitoring in coal mines.
The Gondwana wildfire study looks at ancient coal-rich areas. In contrast, methane monitoring looks at modern coal-linked climate risks.
Together, both reports show that coal has two climate roles. First, coal rocks store old climate records. Second, coal mining today can add to climate risk.

ABC Live Critical Analysis
This study has clear value.
First, it makes old fire study more reliable. Earlier visual methods created doubt. However, lab-based tests now give stronger proof.
Second, the study shows that ancient fires shaped forests and coal-rich areas. Therefore, fire was an important part of Earth’s old climate system.
Third, it strengthens India’s role in old climate research. Indian Gondwana basins hold records that can help explain global climate change over long periods.
However, the study should not be stretched too far. Permian fires were not the same as modern wildfires. The air, plants and land systems were different.
Even so, the study helps scientists understand how fire, climate and life interact over time.
What This Study Does Not Say
The study does not say that modern wildfires and Permian wildfires are the same.
It also does not directly predict future fires.
Instead, it gives scientists a better way to read old fire records. Therefore, it should be seen as a strong step in past climate study, not as a direct future forecast.
Why This Research Matters Now
Wildfires, heat waves and climate stress are now major global concerns. Because of this, old fire records have become more useful.
They show how forests and land systems reacted to fire in the past. They also help scientists study carbon change over long periods.
Moreover, this research can help improve climate models. Better models can help explain how plants, fire and carbon systems respond to stress.
Key Takeaways
| Issue | ABC Live Reading |

Conclusion
The finding of ancient Gondwana wildfires in Indian coal rocks is an important step in climate science. It shows that coal basins store more than fuel. They also store Earth’s old fire and climate records.
By using visual study, Raman testing and FTIR testing, BSIP scientists reduced doubt in identifying fire-made microcharcoal. As a result, they gave researchers a better way to study ancient wildfires.
The larger message is clear. India’s coal basins are not only mining zones. They are also climate archives. Therefore, studying them can help scientists understand Earth’s past and prepare better for future climate risks.
