Keywords:LA-ICP-MS, tourmaline, elbaite, paraiba tourmaline

Chemical Analysis of tourmaline using LA-ICP-MS is difficult because chemical composition of tourmaline is complex. In this study, we analyzed Paraiba- tourmaline using LA-ICP-MS based on some assumptions and studied the origin determination of Paraiba- tourmaline.
