Suppose a team of scientists is studying the formation of an island chain generated by four extinct volcanoes. To determine when
each volcano became extinct, the scientists calculated the age of the youngest layer of igneous rocks on each island. After a
recent research trip, the identifying tag of a sample rock was lost. The scientists ask you to help identify the sample rock's
parent volcano.
The scientists give you some information.
1) The initial ratio of strontium-87 to strontium-86 in the rock was 0.7129.
2) The decay constant, 1, for rubidium-87 is 1.42 x 10-1!.
3) The current isotope concentrations in the rock are 8" Sr = 126 ppm, 8'Rb = 218 ppm, and 8ºSr = 175 ppm.
