This repository contains the data and code for reproducing Bayesian box modeling of the Neoproterozoic Sr reservoir and isotopic composition presented in the following mansucript:
Macdonald, F.A., Renger, E., Tasistro-Hart, A.R., Byerly, B.L., Jackson, M.G., Bergmann, K.D., Horner, T.J., and Crockford, P.W., 2025, Mantle-like Sr isotopes in a Sturtian cap carbonate in Oman: Geology, v. XX, doi:10.1130/G53385.1.
Use the environment.yml to set up a conda environment with the necessary packages:
conda env create -f environment.ymlAll modeling, analysis, and generation of figures is performed in the strontium_box_model file Jupyter notebook.
The Markov Chain Monte Carlo output used to produce the figures in the manuscript is saved in the models\2025-02-05_smc_12-chains_10k.nc file, which can be loaded in python via Arviz as with trace = az.from_netcdf('models/2025-02-05_smc_12-chains_10k.nc').
