Matrix dependency of baddeleyite U–Pb geochronology by femtosecond-LA-ICP-MS and comparison with nanosecond-LA-ICP-MS

Baddeleyite is a key mineral in geochronology of mafic rocks as it crystallizes in silica-undersaturated systems that do not grow zircon. It has been shown that nanosecond (ns-)LA-ICP-MS U–Pb analysis requires matrix-matched calibration due to significantly stronger element downhole fractionation in baddeleyite com
