Short summary
Zr-bearing accessory minerals in granites from Scotland and Northern Ireland, UK, have been examined with a scanning electron microscope and their compositions analyzed by electron microprobe. Four types of zircon were identified: magmatic, late-stage magmatic, and two hydrothermal types. Baddeleyite, dalyite, zirconolite, a eudialyte-group mineral, probable lemoynite, and Zr-bearing aegirine were also identified. These accessory minerals are used to help define the magmatic environment.
