Hello Tom, excellent photo! I believe this is one of those "heated-cooled-heated-quenched" cycled chondrules and the "crosses" are the seed/loci of crystallization: the "de-vitrification" of the glass matrix into ordered alignment of the molecules( aka crystallized solid). In other words, this is a frozen example one phase of the chondrule forming process. It is a body that lies between glass/dust and crystallized.
Were we able to watch this process in time lapse we would see the crosses grow in length and width until all the matrix was converted. Elton > Tom Philips wrote: > > >...
