Carbon and uranium radioactive dating

Ordinarily, these reactions are not complete so that various amounts of each of these minerals may exist at any given time.The right branch of the reaction series is a continuum in which the earliest formed calcium-rich feldspar crystals react with the sodium ions contained in the melt to become progressively more sodium rich.

This reaction will continue until the last mineral in the series, biotite mica, is formed.

To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating.

Radiometric dating is largely done on rock that has formed from solidified lava.

Such processes can cause the daughter product to be enriched relative to the parent, which would make the rock look older, or cause the parent to be enriched relative to the daughter, which would make the rock look younger.

This calls the whole radiometric dating scheme into serious question.

During the last stage of crystallization, after most of the magma has solidified, the remaining melt will form the minerals quartz, muscovite mica, and potassium feldspar.
