Large-magnitude extension along metamorphic core complexes of western Arizona and southeastern CAlifornia: Evaluation with paleomagnetism
Article Abstract:
Research investigating the magnitude of the tilting of the metamorphic rocks in the footwall region of Harcuvar, Buckskin and Harquahala in California and Western Arizona, United States, is presented. Particular attention is given to paleomagnetic evaluations.

Paleomagnetism of the Dockum Group (Upper Triassic), northwest Texas: further evidence for the J-1 cusp in the North America apparent polar wander path and implications for rate of Triassic apparent polar wander and Colorado plateau rotation
Article Abstract:
The characteristic magnetization of the non-hematitic sandstones of the upper Carnian-lower Norian Dockum Group is an 'early' magnetization acquired at the time of or after deposition. But the characteristic magnetization of the red bed sites has been analysed as secondary magnetization of earliest Jurassic age. The observation of conflicting magnetostratigraphies support the secondary origin of this magnetization. The general position of the J-1 cusp shown by poles in the Piedmont province, the Newark basin and the Colorado plateau is confirmed and the magnitude of rotation of Colorado is less than 5 degrees.

Paleomagnetic data from the Carborca terrane, Mexico: Implications for Cordilleran tectonics and the Mojave-Senora megashear hypothesis
Article Abstract:
It has been proposed that the truncating structure of the Caborca terrane of northwest Mexico is a Middle to Late Jurassic left-lateral strike-slip fault, referred to as the Mojave-Sonora megashear (MSM) by Anderson and Silver (1979). There is evidence supporting the MSM hypothesis, but this is not conclusive. Paleomagnetic techniques can be used to independently test the hypothesis of southeastward displacement of the Caborca terrane.
