Latest Pleistocene and Holocene Geomagnetic Paleointensity on Hawaii

Science, 1993
Geomagnetic paleointensity determinations from radiocarbon-dated lava flows on the island of Hawaii provide an estimate of broad trends in paleointensity for Holocene time and offer a glimpse of intensity variations near the end of the last glacial period.

Holocene geomagnetic paleointensities: A blind test of absolute paleointensity techniques and materials

Physics of the Earth and Planetary Interiors, 2007
Through several decades of research, absolute paleointensity estimates have been obtained from a wide range of rocks with varying ages, covering the last 3.45 Ga years. These paleointensity data are crucial to study the past geodynamo and the geological evolution of the Earth's deep interior.

Introduction to Paleointensity Articles

Reviews of Geophysics, 1988
After indicating the basis of the technique, its use with a cryogenic SQUID magnetometer is outlined, particular emphasis being given to the need for stringent reliability criteria. Comparison of results for some samples is made with results obtained using the Shaw alternating‐field technique, and the agreement is satisfactory.

Paleointensity determinations of lunar samples

Physics of the Earth and Planetary Interiors, 1977
Abstract Evidence for the existence of an ancient lunar field comes from the NRM of lunar rocks and from measurements of local lunar surface magnetic fields. Even when the Fe particles present in the rocks possess enough magnetic stability to preserve a record of the original magnetizing field, there are considerable difficulties in estimating the ...

Absolute paleointensity and magnetomineralogical changes

Journal of Geophysical Research: Solid Earth, 1996
Determinations of absolute paleointensity are often hampered by magnetomineralogical changes produced within samples of lava flows during successive heatings. Such changes which directly affect the capacity for a sample to acquire a partial thermoremanent magnetization (PTRM) are reflected by negative pTRM checks, a deviation between the original pTRM ...
