This dataset contains:

* 'Supplementary Material 1.pdf' : The Supplementary Material 1 contains additional figures referenced in the main text. 

* 'Supplementary Material 2.pdf' : Supplementary Material 2 shows a summary of all profile locations in the triple-zoned olivine and the profile fits from diffusion modeling. 

* 'Supplementary Material 3.pdf' : Supplementary Material 3 discusses how the uncertainty on the pressure, the uncertainty on the eruption dates from oceanographic cruises and a faster diffusion of Mg-Fe in olivine (from Shea et al. 2023) would influence the interpretation of our intrusion dates and their overlap with geophysical data.

* 'Supplementary Tables.xlsx' : The Supplementary Tables contain the composition of olivine from EPMA (Tab "Olivine"), the trace element composition of the olivines from LA-ICP-MS (Tab "Olivine TE"), the normalized magnetite compositions from EPMA (Tab "Magnetite"), the percent of each phase from X-ray tomography (Tab "Tomography"), and the olivine diffusion times with their uncertainty and discrepancy of the fit for a depth of 30 km (Tab "Diffusion Times") and a depth of 17 km (Tab "Diffusion Times (17 km)"). 

* 'Olivine_2D(xy)Video.mp4' : A supplementary video showing the olivine with sieve texture imaged by X-ray tomography as a 2D video of progressive slices through the olivine (color code: Green = Olivine (light green = Fe-rich, dark green = Mg-rich), Red = Magnetite, Purple = Apatite, Yellow = Sulfide, Blue = Embayments (light blue = glassy, dark blue = empty))

* 'Olivine_3DVideo.mp4' : A supplementary video showing the olivine with sieve texture imaged by X-ray tomography as a 3D reconstruction (same color code as 2D video)
