1. Skeptics suggest that the palaeomagnetic data could be corrupted if Earth's ancient magnetic field was substantially different from today's.
2. If the ancient magnetic field was oriented similar to today's field ( North Magnetic Pole near the Geographic South Pole, the strata exhibit reversed polarity.
3. If the ancient magnetic field were oriented similar to today's field ( North Magnetic Pole near the North Rotational Pole ), the strata would retain a normal polarity.
4. William W . Sager, a specialist in the Earth's ancient magnetic field, and Anthony A . P . Koppers, a planetary physicist at the Scripps Institute of Oceanography in San Diego, are reporting on their insights into the behavior of the ancient Earth today in the journal Science.
5. Some evidence comes from analysis of the orientation of the ancient magnetic field preserved by magnetite in ancient lava flows sampled at four seamounts ( Tarduno " et al . ", 2003 ) : this evidence from paleomagnetism shows a more complex history than the commonly accepted view of a stationary hotspot.
6. It's difficult to find ancient magnetic field in a sentence. 用ancient magnetic field造句挺難的
7. Steven Curtis, a specialist in planetary magnetism at the Goddard center, said there was insufficient evidence to determine if the weak Martian magnetism resulted from a field generated by a less active dynamo in a small, cooling planet or if it was merely a remnant of an ancient magnetic field still detectable in the Martian crust.
8. If the hotspot had remained above a fixed mantle plume during the past 80 million years, the latitude as recorded by the orientation of the ancient magnetic field preserved by magnetite ( paleolatitude ) should be constant for each sample; this should also signify original cooling at the same latitude as the current location of the Hawaiian hotspot.
