I want to know the answer to the following question:
When did the Austroalpine peaks undergo their event?
All the background I'm provided with is that "According to geologist Stefan Schmid, because the Western Alps underwent a metamorphic event in the Cenozoic Era while the Austroalpine peaks underwent an event in the Cretaceous Period, the two areas show distinct differences in nappe formations.". Is that enough to answer the question?
