Here is a list of the files included on the supplementary CD.
############################################################################################
Due to limited amount of time, I have not been able to fully comment all of the code and present all of the data in a consistent format. Apologies for the very rough format! I have included all this information regardless in case you need to see some of the inner workings. The olivine DFENS code has the most comprehensive comments. This document will at least try to explain what is in each of the data files.
##########################################################################################
SKU = Skuggafjoll (Chapter 3)
BORG = Borgarhraun (Chapters 4 and 5)
LAK = Laki (Chapter 6)
-------------------------------------------------------------------------------------------------
Olivine EPMA data
Electron probe profiles collected across olivine macrocrysts that were used in diffusion modelling.
BORG_Ol_data.csv (Chapter 4): Compositions are presented in ppm. Initial conditions used in the modelling are also included in this file. sds are averaged standard deviations based on repeat measurements of secondary standards and counting statistics.
SKU_Ol_data.csv (Chapter 3): Compositions also presented in ppm. sd_counts is the standard deviation from counting statistics used by the electron probe. st_dev is standard deviations from repeat measurements of secondary standards.
LAK_Ol_data.csv (Chapter 6): Oxide wt % are presented in this file. _sd are standard deviations based on counting statistics.
-----------------------------------------------------------------------------------------------------
EBSD angle data
Angles between crystallographic axes and directions on the sectioned face on Skuggafjoll olivines. e.g angle100X is the angle between the horizontal in the image (i.e x axis) and [100] axis. angle100P is the angle between the profile and [100]. Calculated from EBSD patterns.
files:
SKU_Ol_angles.csv (Chapter 3)
BORG_Ol_angles.csv (Chapter 4)
LAK_Ol_angles.csv (Chapter 6)
----------------------------------------------------------------------------------------------------
Plagioclase data files
EPMA, SIMS and stepscan profiles collected across plagioclase crystals that were used in diffusion modelling. Elemental concentrations presented in ppm. sd are standard deviations
files:
SKU_Plag_data.csv (Chapter 3)
BORG_Plag_data.csv (Chapter 5)
LAK_Plag_data.csv (Chapter 6)
----------------------------------------------------------------------------------------------------
Spinel Compositional file
BORG_Sp_data.csv (Chapter 5): Oxide wt % are presented in this file. Results from mineral formulae calculations are also included where elements are also presented in atoms per formula unit (_at). Fe3+ was calculated stoichiometrically. Cr# (Cr_no) and Mg# (Mg_no) have also been calculated. No standard deviations are included in this file.
----------------------------------------------------------------------------------------------------
Glass compositional data
BORG_glass.csv (Chapter 5): wt % oxide glass measurement and standard deviations from counting statistics. Matrix glass and nodule melt pockets from Borgarhraun were measured.
---------------------------------------------------------------------------------------------------
DFENS model files
Python scripts used to perform DFENS modelling. Code for each individual in included.
DFENS_Ol_1D.py: Olivine DFENS model (Chapters 3, 4, 6). Code is already included in Appendix C of the thesis.
DFENS_Plag_1D.py: Plagioclase DFENS model (Chapter 3, 6).
DFENS_Sp_2D.py: 2D spinel DFENS model (Chapter 5).
DFENS_Ol_Plag_1D.py : Combined plagioclase-olivine DFENS model (Chapter 3).
pmc.py : PyMultiNest functions used in the DFENS models which were written in collaboration with Oliver Shorttle. This code is also included in Appendix C of the thesis.
