The crust underlying Great Meteor has an age of 85 million years, deduced from the magnetic anomaly 34 (An34) at this location.

[2] The shallow and flat summit of the Great Meteor Seamount, ranging between 150 and 300 m (490 and 980 ft) below sea level, suggests that it may have emerged sometime in the past 30 million years.

The New England hotspot formed the White Mountains 124 to 100 million years ago when the North American continent was directly overhead.

As the Atlantic Ocean continued to spread, the hotspot eventually traveled further east, forming the Great Meteor Seamount where it is found today.

[8] The unique ecological condition of the Great Meteor Seamount is shown by the many endemic copepod and nematode species.
