The Great Meteor hotspot track, also referred to as the New England hotspot track, is a vast trail of hotspot magmatism in the Northern Hemisphere. It exends over 5,800 km (3,604 mi) from Nunavut in Northern Canada to the northern Atlantic Ocean. Volcanism in the hotspot track was produced by the New England or Great Meteor hotspot, with the oldest magmatic activity dating back at least 214 million years ago during the Late Triassic period. This makes the Great Meteor track one of the oldest hotspot tracks on Earth. It contains over 80 volcanoes, with the most recognizable ones located in the Atlantic Ocean where they form seamounts.[1]
Features
Geological features within the hotspot track include:
- Churchill kimberlite field (214-192 Ma)

- Kirkland Lake kimberlite field (165-152 Ma)
- Lake Timiskaming kimberlite field (155-134 Ma)
- Monteregian Hills (120 Ma)
- White Mountains (109 Ma)
- New England Seamounts (100-80 Ma)
- Corner Rise Seamounts (75 Ma)
