Great Meteor hotspot track
Encyclopedia
The Great Meteor hotspot track, also referred to as the New England hotspot track, is a vast hotspot
track in the Northern Hemisphere
, stretching over 5800 km (3,604 mi) from Nunavut
in Northern Canada
to the northern Atlantic Ocean
. Volcanism within the hotspot track is produced by the New England or Great Meteor hotspot
and spans a period of 196 million years during the early Jurassic
period, making it one of the oldest hotspot tracks on Earth. The hotspot track contains over 80 volcanoes, with the most recognizable volcanics located in the Atlantic Ocean where they form seamount

Hotspot (geology)
The places known as hotspots or hot spots in geology are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the mantle elsewhere. They may be on, near to, or far from tectonic plate boundaries. There are two hypotheses to explain them...

New England hotspot
The New England hotspot, also referred to as the Great Meteor hotspot, is a long-lived volcanic hotspot in the Atlantic Ocean. The hotspot's most recent eruptive center is the Great Meteor Seamount, and it probably created a short line of mid to late-Tertiary age seamounts on the African Plate but...

Seamount
A seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface , and thus is not an island. These are typically formed from extinct volcanoes, that rise abruptly and are usually found rising from a seafloor of depth. They are defined by oceanographers as...
