Paleomagnetic study of Middle Jurassic volcanic and volcaniclastic rocks in southeastern Arizona yields a paleomagnetic pole located at 61.8¿N, 116.0¿E (k=49.6, α95=6.2¿). These rocks from corral Canyon represent an autochthonous segment of the Jurassic Cordilleran magnetic arc and were deposited directly on Upper Paleozoic carbonates of the cratonic miogeocline. Rock magnetic experiments demonstrate that the natural remanent magnetization of these rocks is dominantly a single component magnetization carried in both magnetite and hematite phases and is interpreted as a primary thermoremanent magnetism. Rb/Sr isotope geochemistry on whole-rock samples from eight welded ash flow tuffs yields an isochron age of 172.2¿5.8(2&sgr;) Ma. The Corral Canyon pole falls between poles from Newark Trend Group II (179¿3 Ma) and Glance Conglomerate (151¿2 Ma).
