Zircon crystal morphology and internal structures as a tool for constraining magma sources : examples from northern Portugal Variscan biotite-rich granite plutons

In northern Portugal, large volumes of granitoids were emplaced during the last stage (D3) of the Variscan orogeny and display a wide range of petrological signatures. We studied the morphologies and internal structures of zircons from syn-, late- and post-D3 granitoids. The sin-D3 granitoids includ...
