T_c1D - A 1D thermal and thermochronometer age prediction model

T_c1D is a one-dimensional thermal and thermochronometer age prediction model that can simulate the effects of various geodynamic and geomorphic processes on thermochronometer ages. It currently supports prediction of apatite and zircon (U-Th)/He and fission-track ages. Below you will find some essential details about using the code and detailed documentation can be found on the T_c1D documentation site.

Getting started

The easiest way to get started using T_c1D is via the launch binder button above. This will open an interactive demo of T_c1D using Binder. Instructions for how to install T_c1D are below.

Installation

You can install T_c1D in your Python environment using pip.

pip install tc1d

Note: In order for T_c1D to work properly you will also need to install the thermochronometer age prediction programs available in the T_ccore package.

Usage

An example model with 10 km of exhumation and default values can be run from the command line as follows:

tc1d-cli --ero-option1 10.0

A full list of options that can be used with T_c1D can be found by running the code with the --help flag (or no specified flags):

tc1d-cli --help

This will return a usage statement and list of flags the code accepts.
