This is well-established for most isotopic systems.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. 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.

The probability of a parent atom decaying in a fixed period of time is always the same for all atoms of that type regardless of temperature, pressure, or chemical conditions. The time required for one-half of any original number of parent atoms to decay is the half-life, which is related to the decay constant by a simple mathematical formula.

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..

All rocks and minerals contain long-lived radioactive elements that were incorporated into Earth when the Solar System formed.

These radioactive elements constitute independent clocks that allow geologists to determine the age of the rocks in which they occur.

Radiometric dating (often called radioactive dating) is a technique used to date materials such as rocks or carbon, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
