# How to solve carbon dating problems

If three different strontium-containing minerals form at the same time in the same magma, each strontium containing mineral will have the same ratios of the different strontium nuclides, since all strontium nuclides behave the same chemically.

(Note that this does not mean that the ratios are the same everywhere on earth.

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.F, the fraction of K40 remaining, is equal to the amount of potassium-40 in the sample, divided by the sum of potassium-40 in the sample plus the calculated amount of potassium required to produce the amount of argon found. In spite of the fact that it is a gas, the argon is trapped in the mineral and can't escape.(Creationists claim that argon escape renders age determinations invalid.*Carbon*-14 *dating*: See *Carbon* 14 *Dating* in this web site.Rubidium-Strontium **dating**: The nuclide rubidium-87 decays, with a half life of 48.8 billion years, to strontium-87.

Women in Ukraine are brought up in a manner of appreciating family values and one may say little conservative comparing to Western women.
