The new paper by PhD student Tom Boonants on cosmic spherules was picked up by EOS Wetenschappen for a nice and complete summary in Dutch. The original paper published in Meteoritics and Planetary Science can be found here.
Tom characterized cosmic spherules from the Sør Rondane Mountains in East Antarctica and used stable isotopes and elemental fractionation to show that "CAT-like” and “High Ca-Al” types likely represent a continuum between mineral end-members from both primitive and differentiated parent bodies that experienced variable degrees of evaporation.
