Secondary Melt Ornamentation on Westwater, Utah Microspherules: Evidence of an Extraterrestrial Provenance
Published online by Cambridge University Press: 14 March 2018
Extract
Microspherules (MS) ranging in size from 50μm to 425μm were discovered at Westwater, Utah in 1999. Examination of these particles using a scanning electron microscope identifies certain physical features that support an extraterrestrial (ET) provenance for these objects. Energy dispersive spectrometry (EDS) was used to determine the qualitative chemistry of these particles.
