Question

Did you know? Carbon-14 dating only works up to about 50,000 years ago — beyond that there simply isn't enough C-14 left to measure. For older samples archaeologists use potassium-argon (volcanic rock) or uranium-thorium (stalagmites and coral).

Accepted Answer

Carbon-14 dating only works up to about 50,000 years ago — beyond that there simply isn't enough C-14 left to measure. For older samples archaeologists use potassium-argon (volcanic rock) or uranium-thorium (stalagmites and coral).

Koolstof-14-datering werkt alleen tot ongeveer 50.000 jaar terug — daarna is er gewoon te weinig C-14 over om te meten. Voor oudere monsters gebruiken archeologen kalium-argon (vulkaangesteente) of uranium-thorium (stalagmieten en koraal).
