| Conglomerate tests are applied to mechanically disaggregated clasts of a formation whose palaeomagnetism is under investigation. |
| In this paper we show that palaeomagnetism may offer the opportunity to indirectly solve this problem, and date the onset of the Tyrrhenian spreading. |
| From palaeomagnetism we can determine palaeolatitude and the rotation of a terrane through time, but the palaeomagnetic data give no insight into palaeolongitude. |
| The crucial work on palaeomagnetism was already under way less than ten years after Holmes's first edition. |
| It was while considering the behaviour of the magnetic fields of the Sun and the Earth that be became interested in geomagnetism and palaeomagnetism. |
| Dating the site has instead been based upon stratigraphy, palaeomagnetism, and the evidence of fossil flora and fauna in the sediments. |
