Supplementary Information accompanying the thesis "Microanalytical Constraints on the Geometry and Chemical Evolution of Kīlauea’s Volcanic Plumbing System". Information on methods can be found in Chapter 2 of this thesis, and the read me files in the folder for each chapter.

Electronic appendix 1 contains the EPMA profiles across olivine aggregates shown in Chapter 3. For further details, please see the publication https://doi.org/10.1130/G46660.1

Electronic Appendix 2 contains EPMA measurements of glasses and olivines presented in Chapter 4, along with the classification of olivine grains as deformed or undeformed. The MATLAB code used for slip system identification is included (Slip_System_Id.m), along with an example .ctf file of an EBSD map of a deformed grain (Kil2_L3_386.ctf). For further details, please see the publication https://doi.org/10.1038/s41467-019-13635-y

Electronic Appendix 3 contains the compilation of forsterite contents from GEOROC and other sources presented in Chapter 5. Electronic Appendix 4 contains the LAICPMS data presented in Chapters 5, along with information about the precision and accuracy of repeated analyses of standards. For further details, please see the publication https://doi.org/10.1038/s41467-019-13518-2

Electronic Appendix 5 shows concentrations of chalcophile elements in melt inclusions and glasses (integrated with the lithophile data presented in chapter 5), as well as sulfide compositions, and information about analyses of secondary standards. A zip file containing the Jupyter notebook used to model concentrations of Ba and Cu during mantle melting as well as python requirements is also attached. However, it is suggested that readers access this through my github, where I have provided a binder format allowing anyone to run the code without needing to install the relevant python packages. https://github.com/PennyWieser/Sulfide_Present_Melting_GCA_Wieser2020. For further information, please see the publication. https://doi.org/10.1016/j.gca.2020.05.018

Electronic Appendix 6 contains the major and volatile element concentrations presented in Chapter 7. This work will soon be published in G3, where further details can be found.
