Canada is home to ancient volcanic structures, notably the Blake River Megacaldera Complex, a significant geological feature located across the provinces of Ontario and Quebec. This complex represents the remnants of one of the largest and best-preserved ancient volcanic systems on Earth, often associated with the scale of what is commonly referred to as a "supervolcano."
Location and Characteristics
The Blake River Megacaldera Complex is situated within the expansive Canadian Shield, a vast geological core that underlies much of North America. Its precise location spans the border between northeastern Ontario and northwestern Quebec.
Here are the key details regarding its location and age:
| Feature | Detail |
|---|---|
| Coordinates | 48°20′05″N 79°16′20″W |
| Location | Ontario-Quebec, Canada |
| Geological Age | Approximately 2,706 million years ago (Ma) |
| Range | Canadian Shield |
This ancient volcanic complex, formed over 2.7 billion years ago, is not an active supervolcano today but provides crucial insights into early Earth's powerful volcanic processes. Its immense size and the scale of its past eruptions classify it as a prime example of a megacaldera complex.
