Extended calibration of olivine-spinel Al exchange thermometers (OSAT)

Python scripts for the new models of the olivine-spinel Al exchange thermometers (OSAT).

Installation

pip install "git+https://github.com/eazzzon/olspthermo.git"

Requirement

numpy

pandas

scipy

periodictable

Uninstallation

pip uninstall OSAT

Example

To quick run, navigate to the example folder, call the python script as:

python example_calculation.py

or run through the jupiter file.

DON'T change the header/column name of the example excel template files.

Monte Carlo simulation for error progagation

We also provide a MC approach to progagate the analytical errors to the temperature estimation. an example is given by calling

python example_mc.py

or run in the jupyter example.

Excel Spreadsheet & Jupyter notebook

We also provide an excel spreadsheet (OSAT.xlsx ) and example notebook files to calculate temperature with all models. Error progagation will have to go with MC in python
