His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.
He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition.
The only dating methods discussed (over and over again) by evolution-believing scientists and the mass media are ones that supposedly "prove" that the earth is billions of years old.
One of the most popular of these is known as radiometric dating.
For example, In 1973, in Alberta, Canada (near the town of Grand Prarie) a high voltage line fell which caused nearby tree roots to fossilize almost instantly.
When scientists at the University of Regina, Saskatchewan were asked what the results would be if these roots were dated by Potassium Argon method.
They did this because it is almost certain that these lead isotopes were all present in large quantities when the earth was created.
For Uranium/Lead dating this means that some of the uranium that was initially present would be "leached" out of the rock.
Leaching can also cause uranium to be leached into rocks that have little or no uranium in them. Note: As for the few cases where scientists do know what the "original" condition (or date of eruption) was, they still have not been able to come up with the correct "date" for the age of the rock without all sorts of fancy footwork and massaging of data.
Therefore, in virtually every case, scientists do not know what the original condition of the rock was; and, even if they did know, they don't any more due to heat contamination, mixing, and leaching. That's because radiometric dating (with the exception of Carbon 14) is almost always performed on igneous rocks (i.e. Also because, when different substances are in a liquid state, something known as mixing almost always takes place: meaning that whenever a liquid (or molten) rock is erupted out of the earth, both the mother and daughter elements will be "mixed" together, thus making it virtually impossible to determine the time that an eruption took place.
Another problem that calls into question the credibility of radiometric dating is heat contamination.
