Decoding whole rock, plagioclase, zircon and apatite isotopic and geochemical signatures from variably contaminated dioritic magmas

► We examine zircon and apatite from quartz diorite. ► We compare accessory phases with previously analyzed plagioclase. ► Hf and O isotope in zircon and Sr isotope in plagioclase indicate contamination process. ► Trace element in zircon and apatite corroborate isotope results. ► Plagioclase and apatite, but not zircon may be affected by late resorption.
