Nice specimen Michael! Can you imagine how those bubbliciuos vesicles oozed to the top of as whatever cosmic blow-out precipitated them to form out of the melt! This is a "paleo impactite" or "fossil glass", btw, according to some respected colleagues and scientists, but it might take a little while for it to be accepted as such by the mainstream and Met Soc! Thanks kindly for sharing! |
