# meltPT

**meltPT** is a Python package for whole-rock major-element themormobarometric analyses of basaltic (mafic) rocks. It contains modules for:
- Correcting sample compositions for effects of olivine crystallisation
- Estimating pressures and temperatures at which samples were last in equilibrium with the mantle
- Estimating melt fractions and potential temperatures on an individual basis or for a suite of samples

## Installation

### Linux/Mac

To avoid incompatibility issues with other packages you may have installed, 
we recommend running **meltPT** in a virtual environment. Start a terminal and
enter:

```
$ # Create virtual environment.
$ # Replace /path/to/virtual/environment with your desired path.
$ python3 -m venv /path/to/virtual/environment

$ # Activate new virtual environment.
$ source /path/to/virtual/environment/bin/activate
```

Next, download the code. Navigate to your desired location and type:

```
git clone git@github.com:fmcnab/meltPT.git
```

You should now have a directory called "meltPT". To install the package, enter
this directory and run the setup script. Depending on how you plan to use
**meltPT**, you have some different options.

```
$ cd meltPT
$
$ # Basic install - recommended for those who want to use meltPT as it is.
$ pip install .
$
$ # "Editable" mode - recommended for those actively developing meltPT.
$ pip install -e .
$
$ # Including extra dependencies - 
$ # required for those who wish to compile documentation locally.
$ pip install .[docs]
$ pip install -e .[docs] # (editable)
```

This will take a minute or two and print lots of stuff. If it completes
successfully, you are now ready to use **meltPT**!

### Windows

Unfortunately, we don't know much about using Python on a Windows system.
But we plan to find out!

## Using meltPT

Under ./Examples/Tutorials, you will find some exaple scripts to help you get
started.

## Citing meltPT

If you use our code, please cite us. Currently each **meltPT** release is
archived in our Zenodo repository:

*  M<sup>c</sup>Nab, F. and Ball, P. W. (2022), meltPT, version 0.0.9-alpha,
   *Zenodo*, [doi: 10.5281/zenodo.6948030](https://doi.org/10.5281/zenodo.6948030).

Please be sure to include the version number of the code you used, so that
others can reproduce your results. We are working on an accompanying
publication which we hope will be available soon.

We also urge you to cite the original literature on which our code is based.
The sample backtracking method is based on that of 
[Lee et al. (2009, EPSL)](https://doi.org/10.1016/j.epsl.2008.12.020). For
a list of themormobarometric schemes available in **meltPT**, and links to the
original papers, see the\
