Fluid inclusion Rb–Sr isochrons for dating mineral deposits

Not all deposits provide material suitable for conventional radiometric dating, or data which are amenable to unequivocal interpretation. Nor is it easy to verify that such samples have remained isoto... read more

Does climate vary more from century to century when it is warmer?

“The Corchia record is particularly important because it is supported by very detailed radiometric dating using the decay of uranium isotopes, producing one of the best chronologies for this period av... read more

How long does it take stalagmites and stalactites to form?

Limestone stalactites form extremely slowly – usually less than 10cm every thousand years – and radiometric dating has shown that some are over 190,000 years old. Stalactites can also form by a differ... read more

Video: How do we know the age of the Earth?

How do scientists know that? Since there's no "established in" plaque stuck in a cliff somewhere, geologists deduced the age of the Earth thanks to a handful of radioactive elements. With radiometric ... read more
