A 2003 paper by Courtillot, a well-known researcher of these features, et al. proposed five characteristics to distinguish  one type of them. True polar wander is calculated using these features as a reference frame. Products of these features  have a much higher helium-3 to helium-4 ratio than MORBs. Evidence of the Great Meteor one can be found on North  America. The origin of these features was first satisfactorily explained by W. Jason Morgan and they were first proposed  by J. Tuzo (*) Wilson. Analysis of their "tracks" or "trace" constrains the direction and magnitude of plate movement for  approximately the past 200 million years. One of the final steps in the evolution of products of these features is an atoll. These  features are likely formed by mantle plumes. For 10 points, name these geologic features responsible for the creation of volcanic  island chains, like the Hawaiian Islands.
