Craton Radial Anisotropy and Low Velocity Zones imaged with Bayesian and LSQR methods

******************** README for Rad_anisotropy_BOYCE_GRL *****************************

This repository contains data files, inversion software, outputs and plotting codes to accompany the following submitted manuscript:

Boyce, A., Bodin, T., Durand, S., Soergel, D., Debayle, E. Seismic Evidence for Craton Formation by Underplating and Development of the MLD (submitted) Geophysical Research Letters.

The Rad_anisotropy_BOYCE_GRL_V2.tar repo contains:
    • LSQR_inversion - Least Squares inversion of synthetic and real data sets, all input and results and plotting files are included.
    • SRF_Forward_modelling - Codes to make Axisem synthetic models and synthetic data to be inverted with Bayesian Code. Also included are Greens functions from Axisem simulations at 5s minimum period and python codes for forward modelling synthetic S-to-p reciever functions from the Axisem outputs.
    • Bayesian_inversion - Bayesian inversion of synthetic and real data sets, all input files, processed files and plotting codes necessary for reconstructing the posterior distributions are included. Please see https://github.com/alistairboyce11/RJ_MCMC for an up-to-date distribution.
    • MLD_compilation - Our MLD compilation "MLD_compilation_BOYCE_2023.xlsx" and codes to combine this with Fu et al., (GRL 2022) and plot Figure 2 of main manuscript
    • Plotting_for_manuscript
        - Radial_anisotropy_models - codes used to extract data and make plots for Figures S1--S5. Tomographic models available to download at https://ds.iris.edu/ds/products/emc/
        - Figures for Figures 1, 3, 4 in main manuscript.
