Cathodoluminescence (CL) images of zircon from eclogite SW9. a Short prism with straight regular zoning, surrounded by a thin rim of CL-bright zircon, the same material also coating fractures at the interior of the grain. b Mosaic textured zircon. c A CL-dark internal domain with regular zoning but also recrystallized CL-bright domains is surrounded by a CL-bright outer zone showing a very faint regular growth zoning. d Complex chaotic texture with a CL-dark internal domain surrounded by CL-bright rim and cut by similar veins, all parts of the grains suggesting extensive metamorphic recrystallization
