Introduction
The Indian subcontinent is characterized by diverse geological formations, but among them, the Peninsular Plateau is recognized as the oldest landmass.
Geological Significance
- The Peninsular Plateau is primarily composed of ancient crystalline rocks, which are part of the Indian Shield.
- These rocks date back to the Precambrian era, making them over 2.5 billion years old, thus establishing the region's antiquity.
Formation and Structure
- The Peninsular Plateau was formed due to the tectonic activities and geological processes that shaped the Indian landmass.
- It consists of two main divisions: the Deccan Plateau and the Central Highlands, which are characterized by rugged terrain and hills.
Comparison with Other Landmasses
- The Himalayas: Though they are significant, they are relatively younger, formed around 50 million years ago due to the collision between the Indian plate and the Eurasian plate.
- Northern Plains: These are alluvial plains formed by sedimentation from rivers and are much younger than the Peninsular Plateau.
- Island Groups: The islands, such as the Andaman and Nicobar Islands, are also younger formations resulting from volcanic activity and tectonic movements.
Conclusion
The Peninsular Plateau stands as a testament to the geological history of India, making it the oldest landmass of the Indian subcontinent, characterized by its ancient rock formations and significant geological evolution over billions of years.
