Stretching over 16,000 kilometers along the floor of the Atlantic Ocean, the Mid-Atlantic Ridge is one of the most recognizable features on our planet. Reading the Rocks and Magnetic Stripes The age of the Mid-Atlantic Ridge is not a single number but a spectrum determined by distance.
Calculating the Age: Techniques for Determining Mid-Atlantic Ridge Formation
A Dynamic History The age of the Mid-Atlantic Ridge is intertwined with the breakup of the supercontinent Pangaea. By matching these magnetic stripes to the known geomagnetic reversal timeline, researchers can calculate how long ago specific sections of the ridge formed.
60 to 80 million years old Mature section with deep transform faults and older crust. Modern Activity and Endurance.

Region Approximate Age Characteristics Ridge Summit (Spreading Center) Less than 1 million years old Youngest rocks, active volcanism, shallow earthquakes. Therefore, when asking how old the ridge is, the answer is tied to the opening of the Atlantic.
