Three Devonian rock units were collected for paleomagnetic study from the Ste. C¿cile--St. S¿bastien region located in the Gasp¿--Connecticut Valley synclinorium of Qu¿bec Appalachians: 15 sites (48 samples) from the metasediments (subgreenschist facies--siltstones, sandstones) of the Compton Formation (early Middle to late Early Devonian age based on fossil plants) which were tightly folded during Middle Devonian Acadian orogeny; 14 sites (61 samples) from the Ste. C¿cile--St. S¿bastien granitic body (362 m.y., K-Ar age) which intruded the metasediments; 14 sites (62 samples) from the hornfels created subsequent to the emplacement of the intrusive. Detailed thermal cleaning of the metasediments yielded a mean remanence direction characterized by linear vector trajectories, after tilt correction, at D=209¿, I=+20¿, k=30, α95=7.2¿ with unblocking temperature spectrum, 300¿-550 ¿C, carried probably by magnetite. The predeformational origin of this remanence is tested at 99% confidence level as well as antipodal normal and reverse polarity directions. The corresponding paleomagnetic pole, MS, falls at 28 ¿N, 77 ¿E (dp, dm=6¿, 11¿) in agreement with the recently reported poles which are mostly Early Devonian in age and derived from the southeastern margin of the presumed proto-Atlantic ocean. AF demagnetization of granites resulted in a univectorial mean remanence at: (1) D=332¿, I=-39¿; k=31 for N=5 sites in fine-grained granite (FG) unit; (2) D=313¿, I=-25¿; k=19 for N=9 sites in medium-grained granite (MG) unit; and (3) D=319¿, I=-30¿, k=17 for all the total (N=14) granite (G) sites. AF demagnetization of hornfels revealed a post-intrusive mean remanence direction, HF, at D=346¿, I=-22¿, k=8 for N=14 sites. The individual site-mean remanence directions (with coercivity spectra: 10--60 mT) from both granites and hornfels suffer from a large declination spread of about 60¿ but the confidence ovals for the FG and HF remanences overlap. This indicates that the FG and HF remanences are indistinguishable from each other and therefore are proximal in time and probably originated during Middle to Late Devonian period. Interpretation of this kind is speculative in the absence of a convincing evidence for a two (FG younger than MG) or three phase intrusive history of the pluton. Since the pole positions of G (18 ¿N, 150 ¿E), MG (18 ¿N, 158 ¿E), FG (18 ¿N, 137 ¿E) and HF (32 ¿N, 125 ¿E) spread over 40¿ in longitude, these data cannot confirm or negate the possibility of a Mid-Paleozoic transcurrent motion proposed for northern Appalachians. We regard only the pole, MS, with probable late Early or early Middle Devonian age as reliable for the apparent polar path construction.
