Summary:A generalized magnetic polarity history for the Silurian is presented. Preliminary inferences are that most of Silurian time was characterized by periods of mixed polarity, though Wenlock times mainly had a magnetic field of normal polarity. There are indications that the frequency of magnetic field reversals increased from Ordovician to Silurian times (to < 2 m.y. intervals). [R.A.H.]
