The main objective of this project is to constrain the crustal evolution of one of the
largest regions of Neoproterozoic crustal growth on Earth, the Arabian Shield. Combined with
NORDSIM geochronology, high spatial Hf- and O-isotope analysis of dated zircon will lead to a
more sophisticated assessment of relative mantle and crustal contributions than previously
possible, since the isotopic evolution will be directly linked to a dated event. In particular, for
complex polyphase zircon or for metasedimentary rocks containing detrital zircon, source
reservoir information is uniquely obtainable using this combined methodology.
