| الوصف: | [EN] Understanding the drivers of the onset, evolution, and end of eruptions and their impact on eruption style is critical in eruption forecasting and emergency management. The composition of erupted liquids is a key piece of the volcano puzzle, but untangling subtle melt variations remains an analytical challenge. Here, we apply rapid, high-resolution matrix geochemical analysis on samples of known eruption date spanning the entire 2021 La Palma eruption. Sr isotope signatures reveal distinct pulses of basanite melt driving the onset, restart, and evolution of the eruption. Elemental variations in matrix and microcrysts track progressive invasion, and draining, of a subcrustal crystal mush. Associated variations in lava flow rate, vent development, seismicity, and SO2 emission demonstrate that volcanic matrix resolves eruption patterns that could be expected in future basaltic eruptions globally. ; This work was supported by The University of Queensland award UQ-FREA RM2019001828 (T.U.), Australian Research Council Discovery Project DP200101566 (T.U.), Universidad Rey Juan Carlos, URJC Research Groups grant (R.H.), Universidad Complutense de Madrid, Acción Especial AENC1/21-29277 grant (A.Már., E.A., and M.J.H.), and IGME-CSIC project 20223PAL00 (I.G.). ; Peer reviewed |
