As I have mentioned in another post on the Hong Shan Culture and China’s Unique Natural Glass, I have been pursuing an alternative impact site that produced the glass and might have initiated the Younger Dryas cooling. I know that locating the site of this impact can be done most simply by locating the site of the Shui Jing glass mines, which seems unfortunately, and probably for commercial reasons, to be a closely guarded secret in China. You may recall that I have evidence that during such an impact liquid silica was ejected at an angle low enough to form spheres, some as large as 1 metre in diameter. (For more see my second lecture, given last year at Cercle Munster in Luxembourg and posted on Youtube).
Obviously I want to test my hypothesis. If I am correct, the Twin Craters in Inner Mongolia were caused by a recent impact of a dumbell-shaped asteroid, dimensions 250 X 600 metres, which after impact activated a spate of secondary volcanism in Inner Mongolia. If this caused the Younger Dryas, we have to look for something other than a direct comet impact suggested by Graham, as the cause of the calamitous discharge of ice sheet melt. Randal Carlson eloquently argues, as does the geology, that this was a single castastrophe, rather than multiple mini-catastrophes.
The twin craters area of Northern China is littered with surface coal mines, and I have separate evidence that the Hongshan carvers used impact diamonds to carve shui jing natural glass. As in the Popigay Crater in Siberia, microdiamonds formed on impact may well have been concentrated in alluvial deposits (the SG of diamond is 3.52 versus 2.65 for quartz sand). At all events, the finding of nanodiamonds, and other impact ejecta from the stratosphere in Greenland ice cores and in many sedimentary layers at the onset of the Younger Dryas 12,800 years BP, as indicated in Graham’s book, speaks convincingly of an impact on an area loaded with carbon deposits.
However it does not give us the date of the associated catastrophic flood, which I suggest might equally have occurred at the time of dramatic global warming immediately after the Younger Dryas’ abrupt end 11,600 years ago. So an important question is, what scientific data is there on the time of the massive Scablands glacial melt flood? 12,800 years BP, or 1000 plus years later, or dunno?
