Assuming a constant natural radiation level, the last drainage of the trapped electrons can be dated back to several hundred thousand years.
Some types of relative dating techniques include climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.
The ten strata systems that compose the “standard geologic column” are the familiar Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous, and Tertiary periods.
Although no absolute methods were available to establish actual dates, Lyell needed to assign very old dates to the strata to make them consistent with the long eons of time that would be necessary to meet the new uniformitarianism theory developed by James Hutton and himself.
Estimates of the absolute age of prehistoric and geological events and remains amounted to little more than inspired guesswork, as there was no scientific basis for testing such proposals.” With this background, it is strange that the “standard geologic column” that identifies the rock strata on the earth and assigns very old ages to those strata was developed by Sir Charles Lyell in 1830.
This was done 100 years before absolute dating methods were available.
