If the following graph represents the decay of strontium-90 in an igneous rock, what event occurred at 0 years on the horizontal axis?

I have a graph with the vertical axis showing the percentage of radioactive element remaining. The values on the vertical axis are 0 (intersecting), 25, 50, 75, and 100. The values on the horizontal axis are 0 (intersecting), 28, 56, 84, and 112. The actual data values are (28,50), (56,25), (84, 12.5), and (112, 6.25). Is the event the formation of the rock?
