N2 - This study reports the first Si isotope data measured in zircon using nanosecond laser ablation multiple collector inductively coupled plasma mass spectrometry. Long-term (>2 years) external reproducibility obtained on the 91500 zircon standard is 0.13 parts per thousand and 0.21 parts per thousand (2SD) for delta Si-29 and delta Si-30 (per mil deviation from the quartz reference NBS 28), respectively, and typical precision on a single run is on the order of 0.10 parts per thousand and 0.12 parts per thousand (2SE) for delta Si-29 and delta Si-30, respectively. Our results show good consistency between laser ablation multiple collector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) and solution multiple collector inductively coupled plasma mass spectrometry (S-MC-ICP-MS)/secondary ionization mass spectrometry (SIMS) data demonstrating that the Si isotopic composition of zircon can be accurately measured by LA-MC-ICP-MS. Obtained delta Si-30 values on natural zircon standards range from -0.32 +/- 0.23 parts per thousand (2SD) for 91500 to -0.47 +/- 0.17 parts per thousand for MudTank, whereas the MUN (synthetic) zircon standards have lower delta Si-30 values around -2.0 parts per thousand (e.g.-2.08 +/- 0.17 parts per thousand for MUN-1-2b). Silicon isotope measurements by LA-MC-ICP-MS open new possibilities for studying zircon formation in various geological contexts.
