K ar dating calculation
A second problem is that for technical reasons, the measurement of argon and the measurement of potassium have to be made on two different samples, because each measurement requires the destruction of the sample.If the mineral composition of the two sample is different, so that the sample for measuring the potassium is richer or poorer in potassium than the sample used for measuring the argon, then this will be a source of error.Borrower's Oath (For Residential Housing but not Section 232 Projects) - to be used for transactions where HUD issued a firm commitment dated on or after September 1, 2011, but before August 10, 2014.

As a result under most circumstances we don't expect to find much argon in igneous rocks just after they've formed.
