Evaluation of models proposed for the 1991 revision of the International Geomagnetic Reference Field Evaluation of models proposed for the 1991 revision of the International Geomagnetic Reference Field
The 1991 revision of the International Geomagnetic Reference Field (IGRF) comprises a definitive main-field model for 1985.0, amain-field model for 1990.0, and a forecast secular-variation model for the period 1990-1995. The five 1985.0 main-field models and five 1990.0 main-field models that were proposed have been evaluated by comparing them with one another, with magnetic observatory...

Low intensity of the geomagnetic field in early Jurassic time Low intensity of the geomagnetic field in early Jurassic time
From a large collection of Jurassic continental tholeiites cropping out in Europe and Africa, we selected 90 samples for paleointensity determinations. The samples were carefully selected to avoid any secondary magnetizations, especially viscous magnetization. Use of the Thellier method reveals that magnetic property changes due to heating begin often at quite low temperatures but...
