What type of rock is used for radioactive dating

(Creationists claim that argon escape renders age determinations invalid.

However, any escaping argon gas would lead to a determined age younger, not older, than actual.

The creationist "argon escape" theory does not support their young earth model.) The argon age determination of the mineral can be confirmed by measuring the loss of potassium.

At this point the fraction of Rb87 = Sr87 = 0.500; at half life = 2.00, Rb87 = 25% and Sr87 = 75%, and so on. 131, Strahler, Science and Earth History: Points are taken from these curves and a plot of fraction Sr-87/Sr-86 (as ordinate) vs. It turns out to be a straight line with a slope of -1.00.

Strontium-86 is a stable element that does not undergo radioactive change.

In addition, it is not formed as the result of a radioactive decay process.

The decrease in the amount of potassium required to form the original mineral has consistently confirmed the age as determined by the amount of argon formed.
