Radiometric dating of rocks
Each chemical element, such as carbon and oxygen, consists of atoms unique to it.Each atom is understood to be made up of three basic parts. 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.Molten lavas, which successively erupted onto the earth’s surface through volcanic vents and fissures, flowed over already deposited layers of siltstones.
So let’s take a closer look at these methods and see how reliable they really are.
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.
