\n[expand title=”Description:” startwrap=”” endwrap=”<\/strong>“]Detailed rock magnetic measurements and electron microscopy are used to chart the dissolution of magnetite and its slow replacement by greigite as the principal magnetic mineral in rapidly deposited marine sediment cores collected off the coasts of Oman and Northern California. The key observation is that growth of greigite occurs over prolonged timescales (10s to 100s of thousands of years), which will lead to smoothing of any paleomagnetic signal that is recorded in these sequences. We show that published rock magnetic data from many other cores around the world also show similar trends, suggesting that this problem might be widespread.[\/expand]<\/p>\n
