Zircon U-Pb isotope data are presented for eight plutonic rocks from the Masirah ophiolite and one plutonic rock from the Ra's Madrakah ophiolite (South East Oman). These data constrain the age of formation of the two ophiolite nappes exposed on Masirah Island (early Cretaceous), whereas two intrusions with younger ages (late Cretaceous) overlap with the proposed emplacement age of the ophiolite. The data cover two sites in the Masirah Lower Nappe, two sites in the Masirah Upper Nappe (on Masirah Island, off the SE coast of Oman) and one site on Ra's Madrakah (on the mainland of Oman).
Data collection was done using chemical abrasion isotope dilution thermal ionisation mass spectrometry (CA-ID-TIMS) at the NERC Isotope Geosciences Laboratories at the British geological Survey, supported by NERC Isotope Geosciences Facilities award IP-1919-0619. This work resulted from a PhD project funded by NERC GW4+ DTP grant NE/L002434/1.
