Webcams college girls - Dating age of the earth
The Solar System was formed around 4.6 billion years ago, out of the collapse of a dense cloud composed of dusts and gases.
Meteorites, which are the very components of our planets (through the process of accretion), are the remnants of the Solar System’s origins.
Dating meteorites thus allows us to give a lower age to the Solar System (4,56 billion years old).
Lead isotope isochron that Clair Patterson used to determine the age of the solar system and Earth (Patterson, C., 1956, Age of meteorites and the earth: Geochimica et Cosmochimica Acta 10: 230-237).
The animation shows progressive growth over 4550 million years (Myr) of the lead isotope ratios for two stony meteorites (Nuevo Laredo and Forest City) from initial lead isotope ratios matching those of the Canyon Diablo iron meteorite.
