The Cenerigneisses, amphibolite facies metasediments from Serie dei Laghi (Southern Alps), contain heterogeneous zircon populations which gave ages spanning from around 430 to more than 1000 Ma. A detailed chemical study of zircons, supported by careful evaluation of cathodoluminescence images, shows that it is possible to recognize and characterize different growth stages and to relate them to petrogenetic processes.

Abstract
The Cenerigneisses, amphibolite facies metasediments from Serie dei Laghi (Southern Alps), contain heterogeneous zircon populations which gave ages spanning from around 430 to more than 1000 Ma. A detailed chemical study of zircons, supported by careful evaluation of cathodoluminescence images, shows that it is possible to recognize and characterize different growth stages and to relate them to petrogenetic processes.
