Examine the cross section through a hypothetical ocean basin. Using the magnetic time scale at left we find the Jaramillo normal subchron is 1 million years old. The field data indicates that the distance to this anomaly is 25 km from the central rift zone. With this information you can calculate: 1) The half spreading rate cm/year 2) The full spreading rate cm/year
