These are some samples of the “Iron Glaze” that I discovered in the centres of two little crop circles near Cherhill, Wiltshire, in 1993.  Dr. Levengood decided that the iron was dust from the recent Pleiades meteor shower that had been caught in the crop-circle-making vortex, and it had been fused onto the pebbles and plants by instantaneous heat -- so brief that it didn’t burn the crop. 

Perhaps it is more reasonable to accept hoaxer Rob Irving’s contention that he dusted the centres of the circles with iron powder bought at a science supply store.  So much for my moment of fame!  ;o)
