 by the Potassium-Argon dating process. So instead, the rocks surrounding the fossil is dated. Their assumption that the fossil is the same age as the surrounding rock allows them to do this kind of data collecting. What they do is to take samples of the rock layers above and below where the fossil or specimen is located. Then these rock samples are dated. The researcher then assumes that the dates he or she gets are good minimum and maximum ages for the fossil.

The kinds of rock that this process is thought to work best with is various kinds of igneous rocks, volcanic rock and ash.

Biotite and hornblende give the best dates from an evolutionary perspective. Hornblende give the best date that agree with the evolutionary time scale, but biotite is much more abundant and can keep it's Argon under various weathering conditions. The following rocks which are igneous and/or metamorphic minerals, can also be dated by Potassium-Argon: Sanidine, anorthoclase, plagioclase, leucite, nepheline, muscovite, phlogopite, and lepidolite. Whole rock basalt (lava) and some report that ash can also be used. The only sedimentary rock which can be dated is glauconite, but the results are not always considered reliable by evolutionists.

Potassium 40 (K 40) is one of three isotopes of Potassium (K) that is found in the earth's crust (see the graphic to the left or above). Both Potassium 39 and 41 are stable and accounts for 99.99% of all the Potassium found on the earth. Potassium 40, on the other hand, only accounts for 0.0117% of the earth's Potassium. K 40 is also radioactive, because it has odd numbers of both protons and neutrons in its nucleus.

K 40 has a half-life of 1.26 billion years, but when it breaks down, there are three possible ways that it can degrade. If a K 40 atom degrades by beta decay then a Calcium 40 atom is produced. However, if the degradation is by either electron capture or positron decay, then Argon 40 is produced. The beta decay is a faster process. For every 88.8 atoms that convert into a Ca 40, only 11.2 convert into Ar 40. The 88.2 to 11.2 is called the branching ratio.

If a kelvin 40 atom degrades by beta decay then a Calcium 40 atom is produced. However, if the abasement is by either electron capture or positron decay, then Argon 40 is produced. The beta decay is a faster procedure. For every 88.8 atoms that convert into a Ca 40, entirely 11.2 convert into Ar 40. The 88.2 to 11.2 is called the branch ratio.
