Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years. Mountains have been built and eroded, continents and oceans have moved ...

A team of University of Massachusetts geologists is exploring a new way to determine the ages of ancient rocks, and refining our understanding of the timing and rates of the geologic events that have ...

New geologic dating techniques provide a greater resolution of Earth’s history AMHERST, Mass. – A team of University of Massachusetts geologists is exploring a new way to determine the ages of ancient ...

Scientists at The Australian National University (ANU) have found that independent estimates from geology and biology agree on the timing of the breakup of the Pangaea supercontinent into today's ...

The analysis dated the site's streaky gray rocks, part of an outcrop called the Nuvvuagittuq Greenstone Belt, to 4.16 billion ...

A geologist's revisionist theory pushing the formation of the Isthmus of Panama back 10 million years casts doubt on mainstream ideas of what caused the last ice age as well as the global glaciation ...

Dedicated at the University of Chicago on October 10, 2016. In 1946, Willard Libby proposed an innovative method for dating organic materials by measuring their content of carbon-14, a newly ...

The new method offers greater efficiency, and access to a much more detailed geologic record than current dating methods, the scientists say. The successes of the early phases of the research have led ...

Independent estimates from geology and biology agree on the timing of the breakup of the Pangaea supercontinent into today's continents, scientists have found. Scientists at The Australian National ...
