So all we'd have to do is measure the amount of 40K and 40Ar in the rock, and since we know the decay rate of 40K, we can calculate how long ago the rock was formed. Note that time is expressed in millions of years on this graph, as opposed to thousands of years in the C graph. The measurements were done by the argon-argon method. How are Samples Processed? This suggests an obvious method of dating igneous rocks. Applications[ edit ] Due to the long half-life , the technique is most applicable for dating minerals and rocks more than , years old. However, this only works if all the excess argon did indeed come from the atmosphere. Ar—Ar dating is a similar technique which compares isotopic ratios from the same portion of the sample to avoid this problem. Eventually, potassium-argon dating may be able to provide dates as recent as 20, years before present. The time of 65 million years was associated with the K-T boundary from these studies.
