In addition to the ages of Earth, Moon, and meteorites, radiometric dating has been used to determine ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and the age and duration of a wide variety of other geological events and processes.

The above equation makes use of information on the composition of parent and daughter isotopes at the time the material being tested cooled below its closure temperature.

These dating techniques, known as radiometric dating, are firmly grounded in. Pieces of Mars have been found on Earth, and new ones fall down to our world.

Some 120 specimens out of the more than 60,000 meteorites in.

Isochron dating uses the fact that inert isotopes of an element have exactly the same chemical.

Meteorites: 4,300 - 4,600 million years Moon Rocks: 3,500 - 4,200 million years..

Plotting an isochron is used to solve the age equation graphically and calculate the age of the sample and the original composition.

However, construction of an isochron does not require information on the original compositions, using merely the present ratios of the parent and daughter isotopes to a standard isotope.

But the big breakthrough came with the invention of radiometric dating.. The first attempt to find the age of the Earth solely from scientific.
