Cosmogenic burial dating dating services love type selector

I’ll consider four commonly used cosmogenic nuclides: Ne-21, Be-10, Al-26, and Cl-36 (both He-3 and Ne-21 are stable, so they’re pretty much equivalent for purposes of this discussion and I’ll only talk about Ne-21).

That of Cl-36 is also fairly accurately known (0.7%). Nearly all these measurements include chemical processing at the University of Washington, and AMS analysis at LLNL-CAMS.This is hard to estimate in a general way — it depends on the rock or mineral in question and its composition — so for purposes of the following discussion I’ll assume that we know these ratios accurately (however, this is a major issue for some nuclide pairs).Given these ingredients, we can make an uncertainty estimate for all six nuclide pairs implied by these four nuclides.BALCO, Greg, Berkeley Geochronology Center, 2455 Ridge Road, Berkeley, CA 94709, [email protected] ROVEY, Charles W., Geography, Geology, and Planning, Missouri State University, 901 S.National, Springfield, MO 65897Cosmogenic-nuclide burial dating is a means of dating rocks and sediments that have experienced a period of exposure to the cosmic-ray flux at the Earth's surface, followed by burial under sufficient overburden to stop most of the cosmic-ray flux.
