From a University of California – Santa Barbara Press Release: “In the entire geologic record, there are only two known continent-wide layers with abundance peaks in nanodiamonds, impact spherules, and aciniform soot. These are in the 65-million-year-old Cretaceous-Paleogene boundary layer that coincided with major extinctions, including the dinosaurs and ammonites; and the Younger Dryas boundary event at 12,900 [...]
This just in from Popular Science, link here. Massive Extraterrestrial Rock Hit Earth 13 Millennia Ago, According to Nano-Evidence About 13,000 years ago, a chunk of a comet or asteroid hurtled into the atmosphere at a shallow angle, superheating the atmosphere around it as it careened toward the surface. The air grew [...]
One of the many fun things about blogging is that ideas, speculation, and research will often come in “over the transom” from readers. I was recently contacted by Mr. Carl Blanchard with what appears to be long simmering evidence of an Alaskan mega-tsunami at our favorite time period, the Pleistocene-Holocene transition. [...] At the end of the Pleistocene a Younger Dryas “black mat” was deposited on top of the Pleistocene sediments in many parts of North America. A study of the magnetic fraction (~ 10,900 ± 50 B.P.) from the basal section of the black mat at Murray Springs, AZ revealed the presence of amorphous iron oxide [...] http://www.sciencedirect.com/science/article/pii/S0012821X1100690X iPaper_embed(’79972389′, ‘key-y6alm3f9ndc57vgfupt’, ’600′, ’450′); But some bays have no peat! “Analysis reveals that, unlike typical, peat-rich Carolina Bays, Howard Bay essentially lacks peat, diatoms, pollen, and other organic materials, and it also lacks substantial silt and clay. That suggests this Bay never held water for a sustained length of time. Furthermore, the presence of [...] I have always been personally curious about the lack of documented evidence for a tsunami ever occuring on my home coast of North Carolina. Some of the largest undersea land slides on earth have been documented off our wonderful Outer Banks, and earthquakes are not completely unknown in the Carolinas. Both cause big waves. But [...] |
