Scientific paper

Detailed magnetic analyses were performed on magnetic spherules and spheroids found in association with the Ir anomalies at the Cretaceous/Tertiary (K/T) boundary and near the Eocene/Oligocene (E/O) boundary, and on bulk K/T boundary clay from marine and continental sections. It was found that marine K/T boundary clays are strongly magnetic, with remanent coercivities similar to those of the spheroids, while the continental clays are diamagnetic, except for the thin 'impact layer'. The morphologies, mineralogies, and magnetic properties of the K/T magnetic spheroids were found to be closely analogous to those of magnetic fly ash spherules. The late Eocene particles are magnetically distinct from the K/T spheroids, both in their coercivity and thermal spectra.
