Click to expand a text description Three color coded columns.
Column 1 (Nabberu) from top down: crystalline basement rocks, basinal carbonates, Granular IF with smaller bands of argillite throughout and then quartz arenite.
In this activity, you will be able to combine your knowledge of relative dating methods (learned in Activity 7) with the absolute dating method to determine more accurately the geologic history of a region.
These schematic columnar sections contain the stratigraphic sequence for the Transvaal Basin in Africa and the Nabberu Basin and Hamersley Basin in Western Australia.
Electronic course reserves, or "e-Reserves," are articles and book chapters that are available online through the University Libraries.

Half of what remains decays in the next half-life, and half of that in the next, and so on.
This is exponential decay, as seen in the graph of the number of nuclei present as a function of time. Radioactive carbon has the same chemistry as stable carbon, and so it mixes into the biosphere, where it is consumed and becomes part of every living organism.
Then, half of that amount in turn decays in the following half-life.Even if it happens to survive hundreds of half-lives, it still has a 50 percent chance of surviving through one more.Therefore, the decay of a nucleus is like random coin flipping.Carbon-14 dating was not performed on the shroud until 1988, when the process had been refined to the point where only a small amount of material needed to be destroyed.Samples were tested at three independent laboratories, each being given four pieces of cloth, with only one unidentified piece from the shroud, to avoid prejudice.
