Short summary
Baddeleyite is commonly used for U–Pb dating, but textural complexities, alteration features and discordance often make age interpretation difficult. Based on this case study, we discuss strategies for obtaining more accurate baddeleyite ages by high-precision and high spatial resolution methods, including analytical challenges and discordance interpretation. An evaluation of microtextures allows us to distinguish among seven different types of baddeleyite–zircon intergrowths.
