While Randy Koretev was very non committal on meteorite fluorescence he has dug his heels in on this one.From the Bassikounou sample is a microscopic image of a spherule possibly a 4.5 billion year old chondrule.
Only Pb-Pb dating will verify this.
He disputes the image of being of a 4.5 billion old chondrule by supplying this link.
I've responded by stating his link is about 'meteorwrongs', the image is of a meteorite and even if 'round things' do exist in meteorites it doesn't rule out chondrules as the sample is classified as a H5 chondrite originating from one of three possible asteroid candidates 6 Hebe, 3 Juno or 7 Iris.
Currently we have reached an impasse.....
