John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Dating the formation of the Earth is a difficult process, because usually geological dating methods do not work as well. Early in its existence the Earth was more fluid, with materials all mixing together in a super-heated mix. It took millions of years for differentiation and cooling to achieve the layered Earth we live on today. So traditional geological dating gives us more of a lower bound for the age of the Earth, while...

New research has revealed that some events in Earth's history happened more recently than previously thought. Scientists from the British Geological Survey and the Massachusetts Institute of Technology, publishing this week in the journal Science, have refined the data used to determine how much time has passed since a mineral or rock was formed. They report uranium isotopic composition of minerals, used to date major geological events, which are more accurate than previously published. The...

Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science of using decay rates to determine the relative ages of rocks and organic materials. Scientists from the National Institute of Standards and Technology (NIST), working with researchers from Purdue University, the University of Tennessee, Oak Ridge National Laboratory and Wabash College, tested the hypothesis that solar radiation might affect the rate at which radioactive elements decay...

The argument over whether an outcrop of rock in South West Greenland contains the earliest known traces of life on Earth has been reignited, in a study to be published in the Journal of the Geological Society on 23 February. The research, led by Martin J. Whitehouse at the Swedish Museum of Natural History, argues that the controversial rocks "Ëœcannot host evidence of Earth's oldest life', reopening the debate over where the oldest traces of life are located. The small island of...

Many people believe fossils are petrified bone or impressions of a shell in rock. But fossils actually are any type of evidence of the existence of a once-living organism - plant or animal. Accurately dating the age of the Earth is commonplace today. Take a few rocks, analyze them on fancy machines, and presto, out pops the Earth's age. But these techniques are not new. A century ago, B.B. Boltwood outlined the basics. Boltwood got his doctorate from Yale University in 1897. A decade...
