The Steens Mountain (Oregon) geomagnetic polarity transition: 2. Field intensity variations and discussion of reversal models
We carried out an extensive paleointensity study of the 15.5±0.3 m.y. Miocene reversed-to-normal polarity transition recorded in lava flows from Steens Mountain (south central Oregon). One hundredExpand

The Steens Mountain (Oregon) geomagnetic polarity transition: 3
There is disclosed apparatus for rewinding a web. The apparatus comprises a simple inexpensive clutch arrangement which gradually applies and removes driving force from a rewind shaft. A pair ofExpand

Evidence for a 20° tilting of the Earth’s rotation axis 110 million years ago
True polar wander (TPW), the shift of the Earth's rotation axis with respect to the entire globe, is most probably due to mass redistribution in the Earth's mantle as a result of convection. Using aExpand

Magnetic properties and opaque mineralogy of drilled submarine intrusive rocks
Summary Measurements of natural remanent magnetization (nrm), Curie temperature, ferrimagnetic and paramagnetic susceptibility, saturation induced and remanent magnetizations, coercive forces,Expand

Investigating the reasons for the failure of palaeointensity experiments: a study on historical lava flows from Mt. Etna (Italy)
SUMMARY A refined palaeointensity experiment, accompanied by rock-magnetic studies, has been carried out on six lava flows from 1910 and 1928 from Mt. Etna. The purpose of the study was to try toExpand

Single-domain chemical, thermochemical and thermal remanences in a basaltic rock
SUMMARY Tiny basaltic samples containing finely grained titanomagnetite with Curie temperature less than 100°C were heated in air in weak field (25–100μT) at temperatures between 400°C and 560°CExpand

40Ar/39Ar dating of a tephra layer in the Pliocene Senèze maar lacustrine sequence (French Massif Central): constraint on the age of the Réunion–Matuyama transition and implications on
Abstract The sedimentary sequence cored in the Seneze maar (Velay, France) is very favourable for magnetostratigraphy of the Late Pliocene and for studying the paleoenvironmental changes thatExpand

Rotation of the Oman ophiolite and initial location of the ridge in the hotspot reference frame
Abstract The volcanic units of the Oman ophiolite were paleomagnetically studied in order to better constrain the large rotation of the nappe during emplacement suggested by previous paleomagneticExpand

Intensity of the Earth's magnetic field: Evidence for a Mesozoic dipole low
The variation of the strength of the Earth's magnetic field throughout geological time is known only poorly. Large uncertainties spoil indirect paleointensity determinations based on magnetic anomalyExpand
