Professor Valley said that the study strengthens the theory of ‘a cool early Earth’ where temperatures were low enough for liquid water, oceans and a hydrosphere not long after the planet's crust congealed from a sea of molten rock.
The study was conducted using a new technique called atom-probe tomography that along with tried-and-tested ion mass spectrometry, which allowed the scientists to accurately establish the age and thermal history of the zircon by determining the mass of individual atoms of lead in the sample.
The Pittsburgher co-wrote and featured on The Way, which the Boca Raton native recorded for her 2013 debut album Yours Truly. Their on-and-off relationship ended mid-2013 and briefly spurted back into being in 2014 before fizzling again.

A 4.4 billion-year-old zircon crystal (pictured) is now confirmed to be the oldest bit of the Earth's crust and is providing new insight into how the early Earth cooled from a ball of magma and formed continents just 160 million years after the formation of our solar system The study strengthens the theory of ‘a cool early Earth’ where temperatures were low enough for liquid water, oceans and a hydrosphere not long after the planet's crust congealed from a sea of molten rock.
The team of international scientists led by Professor Valley used lead isotopes to date the Australian zircons and identify them as the oldest bits of the Earth's crust, as well as the oldest known material of any kind formed on Earth.
That is the background to the intellectual drama being played out in this series of papers.
