Paleomagnetism of Mafic Dikes in the Northern Pilbara Craton, Western Australia
Two well preserved Archean cratons, Kaapvaal and Pilbara, have remarkably similar geological successions during the Archean and Paleoproterozoic. This has led some to propose that the two may have been connected during that interval, thus experiencing similar tectonic events. We sampled Archean and Proterozoic rocks from the Pilbara craton in order to test the Vaalbara hypothesis, especially th...

متن کاملIncidence and cohort prevalence for autism spectrum disorders in the Avalon Peninsula, Newfoundland and Labrador.
BACKGROUND Recent studies have reported increased prevalence for autism spectrum disorders in a number of geographical locations. Our objective was to determine the incidence and 1-year cohort prevalence for autism spectrum disorders in children less than 15 years of age and living in the Avalon Peninsula at the time of diagnosis. METHODS Retrospective and prospective data were obtained from ...
متن کاملPaleomagnetic Evidence for PostDevonian Displacement of the Avalon Platform Newfoundland
The possibility that the Avalon Platform, where the Avalonian lithotectonic belt is best developed, was involved in late Paleozoic displacement was tested by paleomagnetic study of red sandstones of the Upper Devonian Terrenceville Formation of eastern Newfoundland. Two magnetization directions were identified by thermal demagnetization analysis of 60 oriented samples from 10 sites: a high bloc...
متن کاملOrdovician paleomagnetism of eastern Yunnan, China
Three magnetic components have been isolated in Ordovician formations of the Yangtze Paraplatform (South China Block). Two of these (Daqing A and Hongshiya B components) yield paleopoles that conform to the Carboniferous to Triassic segment of the apparent polar w•der path for South China, and are therefore interpreted as remagnetizations. The third component (declination/inclination = 30!ø/+66...
