AN EXTRATERRESTRIAL ORIGIN FOR WESTWATER, UTAH MICROSPHERULES DETERMINED BY IDENTIFICATION OF SECONDARY MELT CHARACTERISTICS
A scanning electron microscope with energy dispersive spectrometry was employed to investigate these particles. Basic chemistry results are suggestive but not a defining factor in determining microspherule history. However, specific secondary melt characteristics observed as ornamentation on microspherules greater than 200µm and less than 600µm (?) support the extraterrestrial provenance for these particles.
