Short summary
We show that metamorphosed sedimentary rocks in the Western Alps have a detrital zircon signature that connects them to the Adrian plate along the Gondwana margin. We used zircon to learn that a jadeite-bearing orthogneiss intruded into these strata in the Ordovician (at ~460 Ma) and was metamorphosed at high pressure during early Alpine subduction of Adria beneath Europe at ~78 Ma. Our results are consistent with the complex subduction of Adria before full-on collision with the European plate.
