Archaeomagnetic field models cover longer timescales than historical models and may therefore resolve the motion of geomagnetic features on the core–mantle boundary (CMB) in a more meaningful statistical sense. Here we perform a detailed appraisal of archaeomagnetic field models to infer some aspects of the physics of the outer core.

The layers above a hydrocarbon reservoir can present very idiosyncratic characteristics. One characteristic which can be found is concerning a formation with an abrupt velocity inversion, in other words, a layer with abnormally low P and S wave velocities.
