High precision zircon U-Pb data for plutonic rocks from the Masirah and Ra's Madrakah ophiolites, South East Oman
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). The interpretation and discussion of these data form part of a manuscript submitted to Geochemistry, Geophysics, Geosystems. 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.

- Statement
-
Single zircons were isolated from the rock material using a Selfrag© and standard mineral separation techniques. To minimise the effect of Pb-loss, selected zircons were subjected to chemical abrasion to remove damaged parts of the crystal that likely experienced open-system behaviour (Mattinson, 2005). Uranium-Pb isotopic compositions of individual zircons were determined by ID-TIMS using a 202Pb-205Pb–233U–235U mixed-spike and data reduction was carried out using UPb Redux (McLean et al., 2011). All dates were corrected for initial Th/U disequilibrium and the uncertainties on the tracer and blank compositions were propagated into the measurement uncertainty. The blank contribution was determined by monitoring 204Pb and assuming all common Pb (Pbc) was blank-derived.
