In situ U-Pb geochronology was carried out by laser-ablation ICPMS on baddeleyite and zircon from a quartz gabbro of the Varney Nunatak intrusion (central Victoria Land, Antarctica). Back-scattered electron images reveal that baddeleyite grains from the investigated rock are partially substituted by...
