Lately, some of these commentators promoted the claim that the spherules we collected in an expedition to the Pacific Ocean and analyzed carefully with the best instruments in the world over the past five months, are coal ash. This claim is based on unrefereed comments that superficially examined a few elements out of the dozens we analyzed. To be scientifically credible, any such claim must reproduce the measured abundances of all elements and, in particular, demonstrate the loss of volatile elements — as derived in our paper. Our team member, Dr. Jim Lem, head of the Department of Mining Engineering at the University of Technology in Papua New Guinea, noted: “The region where the expedition was carried, should have no coal mineralization. In addition, coal is non-magnetic and cannot be picked up by the magnetic sled that was used.” Indeed, our “BeLaU”-type spherules have a much higher iron abundance than coal ash. Case closed.
