Editing Fracture zone (section)

===Heirtzler fracture zone===
The [[Heirtzler fracture zone]] was named after James Ransom Heirtzler, who first demonstrated through [[magnetostratigraphy]] that the [[Mid-Atlantic Ridge]] was spreading south of Iceland, providing the first clear evidence for [[plate tectonics]].<ref>{{cite journal|title=James Ransom Heirtzler: A Tribute
