Investigating the utility of a high-temperature Thellier-style paleointensity experimental protocol
High-quality data are vital to the research field of paleointensity, which has long suffered from poor-quality and/or sparse data. Previous paleointensity work has established that repeatedly heating specimens increases the opportunity for thermochemical

Paleointensity database updated [PDF]
The updated version of the paleointensity database will be included in the new package that should be released by Mike McElhinny in May 1998. The new version comprises 1692 data records from 115 references. The database tables are also available as ASCII and Excel files via an anonymous ftp site (ftp.dstu.

Paleointensities on 8 ka obsidian from Mayor Island, New Zealand [PDF]
The 8 ka BP (6050 BCE) pantelleritic obsidian flow on Mayor Island, Bay of Plenty, New Zealand, has been investigated using 30 samples from two sites.

The Cretaceous Normal Superchron (CNS) was first defined in the 1960s to explain the Cretaceous Quiet Zone in marine magnetic anomaly profiles, which includes no or fewer geomagnetic reversals.

Behavior of paleointensity during the Paleogene [PDF]
Abstract Behavior of the intensity of geomagnetic field in the Paleogene was studied by the analysis of the sedimentary rocks of the Russian Plate. It is revealed that in the beginning of the Paleogene the variations of little-amplitude paleointensity (about 0.5 H 0 , where H 0 is the value of modern geomagnetic field taken as 40 μT) were ...

Investigating volcanic paleointensity during the Holocene is important for linking archeointensity and sedimentary paleointensity. Across the globe, the island of Hawaii is one of the most studied subaerial locations.

Twenty‐two sites, subjected to an IZZI‐modified Thellier‐Thellier experiment and strict selection criteria, recover a paleomagnetic axial dipole moment (PADM) of 62.2 ± 30.6 ZAm2 in Northern Israel over the Pleistocene (0.012–2.58 Ma).

Paleointensity Estimates From Ignimbrites: The Bishop Tuff Revisited
Volcanic ash flow tuffs (ignimbrites) may contain single domain‐sized (titano) magnetite that should be good for recording geomagnetic field intensity, but due to their complex thermal histories also contain other magnetic grains, which can complicate ...

The necessity of data availability in maintaining the value and longevity of paleointensity results
Asserting the reliability of paleointensity estimates, or comparing relative reliabilities between vastly or subtly different results is a key challenge for paleointensity studies, which often leaves interpretations of these data rife with ambiguities ...

The state of the geomagnetic field throughout the Precambrian era is largely unknown. Approximately 8% of global paleointensity records account for ∼4 billion years of Earth history.
