Magnetic Stripes on the Seafloor Are Created at
All polarity chrons are the same length of time. Positive magnetic anomalies occur where seafloor basalt has the same polarity as Earths present-day magnetic field. Magnetic Mineral Alignment Wmv Earth And Space Science Interactive Science Notebook Seafloor Spreading Alternating stripes of magnetically different rock were laid out in rows on either side of. . They differ only in the magnetic. Thus at divergent boundaries oceanic crust made of basalt is created. The pattern was symmetric to the ridge supporting the idea of symmetric seafloor spreading. As more and more of the seafloor was mapped during the 1950s the magnetic variations turned out not to be random or isolated occurrences but instead revealed recognizable patterns.
