Hullo Listees Well, having been in hospital for the past few days, and having the most profoundly unpleasant procedure performed on me (email me offlist if interested - I have no pride!!) I have had plenty of time to lie in bed, woozy on morphine, read some stuff relating to the origin of CAIs and I have come to the conclusion that I am still confused as to what the current received knowledge is as to the origin of these bodies. As far as I can tell they were either blown into the protosolar nebula by a nearby supernova (what evidence? Radiometric age? and so on) or they were amongst the first solids to precipitate out of the protoplanetary disk and were blown outwards from the Sun to the outer reaches of the newly formed solar system by solar winds.
Any thoughts? Are they measurably older than the matrix and chondrules we find? Opiatically yours.... dave -- In gentle decay, dave IMCA #0092 [EMAIL PROTECTED] (for IMCA member contact) http://www.meteorites.ic24.net/index.html http://www.meteoritecollectors.org "I have a proof that x^n+y^n=z^n never has integer solutions for n>2.
