The two transform zones that connect the Icelandic rift segments and the mid-Atlantic Ridge close to the Icelandic hot spot, are described in terms of geometry of faulting and stress fields. They differ in age: 8-8.5 My in the north and 2-3 My in the south, illustrating the different stages of maturity in the transform process, from an immature stage illustrated by the South Iceland Seismic Zone to a mature stage shown by the Husavik-Flatey Fault.
