We collected 262 samples at 39 sites in three thick Lower Permian sections along the northwestern margin of the Tarim block. The Lower Permian sections are basalts interbedded with limestones or sandstones, or shallow marine limestones and sandstones alone, all with biostratigraphic age control. Alternating field (AF) and thermal demagnetization experiments remove small secondary components and reveal characteristic magnetizations. Reversed directions (consistent with the Kiaman Reversed Interval), similar directions between basalts, sandstones and limestones, a positive fold test, and apparent polar wander and polarity changes recorded in underlying Devonian sediments all attest to the primary nature of the remanence. Two paleomagnetic poles, one from the limestone section (λ = 65.1°N, φ = 162.5°E, K = 128, A95 = 4.1°, n = 11 sites) and the other from the two basalt sections (λ = 54.5°N, φ = 172.3°E, K = 66, A95 = 4.0°, n = 21 sites), differ primarily in colatitude (8.1 +/- 6.5°) suggesting a difference in magnetization age. Permian paleomagnetic poles from Tarim, Siberia, North China and South China all differ significantly suggesting substantial post-Permian relative motions.
