Is radiometric age dating accurate Cam sex vid web

The decay constants for most of these systems have been confirmed in other ways, adding strength to our argument for the age of the earth., so there is one zirconium (Zi) for one silicon (Si) for four oxygen (O).One of the elements that can stand in chemically for zircon is uranium.The reason that I trust the accuracy of the age that we have determined for the earth (~4.56 billion years) is that we have been able to obtain a very similar result using many different isotopic systems.

Because geochronologists want to measure isotopes with different masses, a mass spectrometer works really well for dating things.

I do think that radiometric dating is an accurate way to date the earth, although I am a geochronologist so I have my biases.

This is an enormous branch of geochemistry called Geochronology.

It is an accurate way to date specific geologic events.

There are many radiometric clocks and when applied to appropriate materials, the dating can be very accurate.

As one example, the first minerals to crystallize (condense) from the hot cloud of gasses that surrounded the Sun as it first became a star have been dated to 4568 plus or minus 2 million years....!! Other events on earth can be dated equally well given the right minerals.

Obviously, if the substance you are measuring is contaminated, then all you know is the age since contamination, or worse, you don't know anything, because the contamination might be in the opposite direction - suppose, for example, you're looking at radio carbon (carbon 14, which is produced in the atmosphere by cosmic rays, and which decays into nitrogen).

Since you are exposed to the atmosphere and contain carbon, if you get oils from your skin onto an archeological artifact, then attempting to date it using radio carbon will fail because you are measuring the age of the oils on your skin, not the age of the artifact.

For example, the element Uranium exists as one of several isotopes, some of which are unstable.
