| 英文摘要 | The mid-Norwegian Margin, part of the North Atlantic Igneous Province (NAIP), is a well-studied volcanic rifted margin formed during the breakup between Greenland and Eurasia similar to 56 Ma, with the largest accumulation of magmatic material hosted by the V & oslash;ring Margin section. Despite extensive study in the area, the main controls on magmatic productivity during continental breakup remain debated. To constrain the drivers of breakup magmatism, we developed an inverse Monte Carlo statistical melting model that infers source mineralogy from basalt chemistry. When applied to basalts recently recovered on the V & oslash;ring Margin, our results reveal a clear shift in source mineralogy during rifting, with peak magmatism coinciding with clinopyroxene enrichment, despite mantle potential temperatures likely being capped below 1500 degrees C. We also establish that, while the proto-Iceland mantle plume played a role during the emplacement of the NAIP, the main driver for the continental breakup magmatism is lithospheric thinning as a consequence of continent breakup. This study provides new insights into the magmatic and geodynamic evolution of the mid-Norwegian Margin, emphasizing the role of lithospheric refertilization in driving breakup magmatism. |
