Short summary
This study examines how trace elements are distributed between melt and crystals during dacite crystallization (675–775 °C, 200 MPa) using a two-step experiment combining long-duration runs and a mineral trap technique. Residual melts were effectively separated and analysed. LA-ICP-MS (laser ablation inductively coupled plasma mass spectroscopy) data for elements like P, Y, Zr, Nb, Cs, Ce, Yb, and U reveal that, while Cs and U stay incompatible, other elements are affected by the type of crystallizing minerals.
