Effect of different parameters on melt production (left axis) and mantle temperature (right axis) for models with and without a proto-LLVP. The parameters varied include (A) internal radiogenic heating ratio \(\:\left(\frac{{H}_{LLVP}}{{H}_{Mantle}}\right)\), (B) core–mantle boundary temperature (TCMB), and (C) mantle potential temperature (TP). Triangles represent models without a proto-LLVP, and circles represent models with a proto-LLVP. Average melt Mass (kg) and Mantle Temperature (K) represent temporal average over the last 200 Myr of the total melt mass and spatially averaged mantle temperature respectively. The parameters kept constant are mentioned within each figure. The data used to calculate the averages are available in figure S5, S6, S7.
