Abstract

Zircon crystals from two felsic dykes belonging to the Maloyanisol dyke swarm (Eastern Azov region, Ukraine) were investigated by EMPA, XRD, FTIR and LA-ICP-MS methods. The analytical results reveal the characteristic features of the crystal chemistry and structure of zircons from both dykes, and show heterogeneity of zircon populations. The identified variations in chemical composition and local amorphization explain the different U-Pb ages of studied zircons and reflect the complex history of magma evolution during the formation of the Maloyanisol dyke swarm.
