Trace element LA-ICP-MS mapping on the example of authigenic calcite

Abstract

© 2019 Author(s). A crystal of authigenic calcite filling the pores of Deltavjatia vjatkensis pareiasaur bone (Kotelnich pareiasaur site, Vyatka River, Russia) was investigated by LA-ICP-MS. Laser and mass-spectrometer operational parameters for trace element analysis were optimized. NIST SRM 610 glass was used for bracketing and CaO was used as an internal standard. Data reduction was performed using GLITTER V4.4 and IOLITE 3.71 software. Trace element geochemical maps were composed revealing the spatial features of calcite crystal.
