Those Stonehenge bluestone monoliths -- we need cosmogenic nuclide dating!


Now that the geologists have admitted that the Stonehenge bluestones have come from multiple provenances, and now that the "quarrying" hypothesis simply seems like a mad aberration, can we please get some proper dating done on the surfaces of all those bluestone erratics lying about at Stonehenge?

Cosmogenic dating is now so ubiquitous in geochronology studies, and so reliable, it seems crazy that the bluestones have not already been studied -- so that we can see, once and for all, whether they are freshly quarried (in which case the outer surface of a monolith should be no older than c 5,000 yrs BP) or whether they have been bombarded with cosmic radiation for tens of thousands -- or maybe hundreds of thousands -- of years.  When were these boulders dumped, and where?  During the Anglian Glaciation, or the Devensian, or some other?  It would be good to know......

This is a simple explanation of what this is all about:

The video attached to the article is interesting too.

Of course the taking of a small rock sample from an exposed surface might be deemed "physical damage", and may cause EH to retreat into full "sacred stone" mode -- but scientifically there is absolutely no excuse for holding back for any longer.  As long as EH continues with the line that the surface of the stones must not be damaged, except by jackdaws and starlings,  the more pseudo-science and mythology will flourish. Goodness knows, there is enough of it about already.......
