Paleomagnetism of 1140 to 1150 million-year diabase sills from Gila County, Arizona

Publikováno v: Journal of Geophysical Research. 77:2115-2128

Diabase sills are abundantly developed in Gila County, central Arizona, and they are isotopically dated as 1140–1150 m.y. Stable magnetizations can be retrieved by AF or thermal demagnetization of the diabase. The over-all mean direction of magneti

Anomalous paleomagnetic poles from late Mesozoic dolerites from Spitsbergen

Autor: Henry Spall

Publikováno v: Earth and Planetary Science Letters. 4:73-78

Late Jurassic-Early Cretaceous dolerites from Spitsbergen have normal and reversed directions of magnetization at low temperatures. After thermal demagnetization, all specimens are reversed. This reversed direction is interpreted as resulting from ma

Paleomagnetism of Precambrian rocks from El Paso, Texas

Autor: Henry Spall

Publikováno v: Physics of the Earth and Planetary Interiors. 4:329-346

Of six Precambrian rock types sampled at 12 sites in the Franklin Mountains, El Paso, Texas, a remanence which is stable to AF and/or thermal demagnetization has been isolated from Red Bluff granite, Franklin Mountain rhyolite, Fusselman Canyon diaba

Precambrian apparent polar wandering: Evidence from North America

Autor: Henry Spall

Publikováno v: Earth and Planetary Science Letters. 10:273-280

Over 95 paleomagnetic pole positions have been determined from North American Precambrian rocks, and they are listed in tabulations by Irving and McElhinny. Using rocks which are isotopically dated, five groups of pole positions can be defined, and t

A paleomagnetic and isotopic age for the Wackerfield Dyke of northern England

Autor: Henry Spall, J.G. Mitchell, D. H. Tarling

Publikováno v: Earth and Planetary Science Letters. 18:427-432

The Wackerfield Dyke is exposed in northern England and its field relationships suggest it could be related to the Eocene Mull Dyke Swarm. Wackerfield Dyke specimens taken from below the zone of surface weathering have a natural remanent magnetizatio

Review of Precambrian paleomagnetic data for Europe

Autor: Henry Spall

Publikováno v: Earth and Planetary Science Letters. 18:1-8

Some 36 paleomagnetic poles are available from Precambrian rock units from Europe, west of the Urals. They allow us to amplify Neuvonen's suggestions, and speculate on the pole path for the interval 1200–2000 my. In order to link younger Precambria
