Statement: Detrital zircon age analysis for provenance of Nicobar Fan sands Samples were taken from sediment gravity flow deposits in cores of Sites U1480 and U1481. A concentrate of heavy minerals rich in zircon obtained using standard heavy liquid techniques was mounted in araldite and polished. Zircon grains were selected randomly and analysed by laser ablation inductively coupled plasma mass spectrometry in the London Geochronology Centre at University College London using a New Wave 193 nm aperture-imaged, frequency-quintupled laser ablation system coupled to an Agilent 7700 ICPMS. Typical ablation parameters were 20-35 µm, 10 Hz repetition rate and an energy fluence of ca. 2:5 J/cm2. Plesovice was used as an age standard (TIMS reference age 337.13±0.37 Ma) to correct for instrumental mass bias and depth-dependent inter-element fractionation of Pb, Th and U. Temora and 91500 zircon were used as secondary age standards. Data were processed using GLITTER 4.4 data reduction software. Calculated 206Pb/238U ages were used for grains younger than 1000 Ma, and the 207Pb/206Pb age for older grains. Grains with a complex growth history or disturbed isotopic ratios, with > +5/-15% discordance, were rejected.
