This is determined by drawing a horizontal line from 0.95 to the decay curve line, and then a vertical line from there to the time axis.

[SE] K-Ar is just one of many isotope-pairs that are useful for dating geological materials.

The red-blue bars represent 40K and the green-yellow bars represent 40Ar.

[SE] In order to use the K-Ar dating technique, we need to have an igneous or metamorphic rock that includes a potassium-bearing mineral.
