A paleomagnetic study of the late Early-early Middle Cambrian Waynesboro Formation in south, central Pennsylvania reveals a pre-folding magnetization which is close to the expected Cambrian field at three sites, while other site mean directions are rotated by as much as 82° from the expected Cambrian field. These results are based on detailed thermal demagnetization analysis of 84 red siltstone and sandstone samples from nine sites collected over a 163 km 2area. Local faulting, fault block rotation, and remanence acquisition during rapid apparent polar wander do not appear to be responsible for the observed remanence deviations. |
