How does magnetic striping occur

WebMagnetic striping occurs when the sea floor spreads and magma from the mantle rises through the Earth’s crust. The “Oceanic Crust” is formed by the magma that turns into a new crust. What causes magnetic anomalies? Titanomagnetite minerals in basalt and gabbros carry the source of these anomalies primarily through permanent magnetization. WebAt 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 …
