23 measurements in the floor of the Vema Fracture Zone show heat flow to be above normal and remarkably uniform between the active spreading centers (HF = 3.5 HFU). A simple thermal model of a transform fracture zone shows that heat flow over the fault plane should equal the means of the heat flows over the two abutting lithospheric plates. This model predicts a rather uniform heat flow between the two spreading centers.
