Dating rocks with uranium 238

Susie Welch, recently retired outreach coordinator at the New Mexico Bureau of Geology, was recognized by Governor Susana Martinez for outstanding accomplishments and invaluable contributions to the state of New Mexico.

Wiens has a Ph D in Physics, with a minor in Geology.

His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.

Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.

Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.

Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.

There are over forty such techniques, each using a different radioactive element or a different way of measuring them.

He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition.

He is presently employed in the Space & Atmospheric Sciences Group at the Los Alamos National Laboratory.

The three main parameters that have to be set are the original amount of uranium and lead in the sample, the rate at which uranium and lead enter and leave the sample, and how much the rate of decay changes.

Uranium-lead dating uses four different isotopes to find the age of the rock.

The reason for stopping at lead is because lead is not radioactive and will not change into a different element.
