Aubrey, Keep working on your book, I'm sure there is a lot of interest in the subject, especially for a source takes all the best research out there and puts it together in a interesting and unified narrative.
Question: > Oblique impacts and those impacting silica rich sedimentary rock favor > tektite production. Tektites are melted and distally ejected terrestrial > rock. I had not heard that Oblique impacts favor tektite production, in fact I thought that high velocity perpendicular impacts favored the vaporized ejecta plume reaching outside the earth's atmosphere. Could you elaborate on the evidence favoring oblique impacts, or provide a link to any research on the topic? Thanks, Mike Fowler Chicago > Hi > > I'm not sure if I qualify as a tektite 'expert', but I have done a lot of > private research.
