A paleomagnetic study of late Triassic to early Jurassic rocks from the Watchung Syncline provides useful new constraints on the complex development of the Newark Basin independent of existing structural data. A baked contact test indicates stable remanent magnetizations are primary. Results from the eastern limb of the fold are used to calculate an early Jurassic pole at Long. 115.1¿E, Lat. 62.2¿N (alpha 95=10.5¿, K=41.4) which is similar to previous Newark Basin results. After results from the western limb were corrected for folding, 32¿ of clockwise discordance remained between data from the western and eastern limbs. This cryptic rotation of Newark Basin strata appears to be localized to the border fault zone and may be due to the presence of left lateral secondary brittle shear zones running parallel to strata of the western limb of the Watchung Syncline.
