YDB impact theory getting better all the time, even allowing for the false starts

3 December 2012

At www.sci-news.com/othersciences/paleoclimatology/article00384.html … researchers in Pennsylvania and South Carolina, and now as far away as Syria, are said to have found a thin layer of sedimentary rock with melt glass material within it – formed at very high temperatures, over 1700 degrees Celsius. It is known as trinitite and forms at the surface from the melting of any sediments that may have been there,  fused with rocks. Something very similar happened when a nuclear airburst occurred in New Mexico in 1945 (testing the bomb). The material is akin to other melted material associated with the Younger Dryas Boundary event. The finding are published in PNAS – and were duly reported by George Howard. The site in Syria is interesting as it lies thousands of miles away from North America. Abu Hureyra has a thick charcoal layer suggesting fire was associated with the melt glass and impact spherules.
