WebJul 19, 2024 · What mechanism has caused magnetic striping of the ocean floor? At spreading centres, this crust is separated into parallel bands of rock by successive waves of emergent magma. When Earth’s geomagnetic field undergoes a reversal, the change in polarity is recorded in the magma, which contributes to the alternating pattern of … WebThis process, called subduction, occurs at the oceanic trenches (figure 6). The entire region is known as a subduction zone. Subduction zones have a lot of intense earthquakes and volcanic eruptions. The subducting plate causes melting in the mantle. The magma rises and erupts, creating volcanoes. WebHow to form magnetic striping: new oceanic crust forms continuously at the mid-ocean ridges. While it cools down, it records the magnetic field during its formation.
