These Python workflows accompany the results presented in:\n\n\u003e Mather, B., Müller, R.D., Alfonso, C.P., Wright, N.M., Seton, M. (In prep.) Subducting seafloor anomalies promote porphyry copper formation.\n\n## Jupyter notebooks\n\n1. __01-Identify-Shear-Zones.ipynb__: workflow to identify age discontinuities in seafloor age grids.\n2. __02-SZ-Subduction.ipynb__: tracks where seafloor age discontinuities intersect subduction zones.\n3. __03-Synthetic-Seamounts.ipynb__: tracks where seamount chains associated with a mantle plume intersect subduction zones.\n4. __04-Conjugate-LIPs.ipynb__: tracks where LIPs and their conjugates intersect subduction zones.\n5. __05-Relationship-to-mineral-deposits.ipynb__: examines statistical relationships to mineral deposits from the Hoggard _et al._ (2020), Nat. Geo. dataset.\n6. __06-Plot-Timeseries.ipynb__: notebook for generating maps of porphyry copper deposits, seafloor anomalies and their intersections with subduction zones through time (associated Python files plot these timeseries in parallel using multiple CPU processors).\n7. __07-Input-to_PU-learn.ipynb__: compiles data to be used in the positive-unlabelled machine learning classifier developed by Alfonso _et al._, (In prep.) These files can be copied into the \"prepared_data\" folder of the [PU-learn workflow](https://github.com/cpalfonso/stellar-data-mining).\n8. __Fig-bathymetry.ipynb__: creates a map of present-day seafloor anomalies.\n9. __Fig-plot-timeseries.py__: creates maps of seafloor anomalies at timesteps specified in the Python script.\n\n## Data\n\nThe `data` folder contains input GPlates data on large igneous provinces (LIPs), seamount chains, and the Hoggard _et al._ (2020), Nat. Geo. dataset of porphyry copper deposits.\n\nAdditional data, including outputs from these Jupyter notebook workflows, can be obtained from Zenodo: [https://doi.org/10.5281/zenodo.10851354](https://doi.org/10.5281/zenodo.10851354).\n\n#### References\n\nHoggard, M.
