Mt-info

This module calculates basic mountain parameters such as average mountain length, width, elevation, Moho depth and erosion rate for three modern collisional mountains, the Himalaya-Tibetan plateau, Alps and Zagros. The details to calculate these parameters are provided in the Supplementary Information of Zhu et al., 2024 (doi: https://doi.org/10.1016/j.epsl.2024.119070).

Datasets

• Natural Earth’s physical vectors (version 4.1.0)
• Global topography data from ETOPO1 at a spatial resolution of one arc-minute (Amante and Eakins, 2009).
• Global Moho depth data from CRUST1.0 at one-degree resolution (Laske et al., 2013).

Packages

• geopandas
• shapely (package for computational geometry)
• rasterio (For accessing the many different kind of raster data files used in the GIS field)

Mt-map

This module provides codes to plot maps of the Himalaya-Tibetan Plateau, Alps and Zagros, from Natural Earth’s physical vectors of mountains, as shown in the Figure 2 of Zhu et al., 2024 (doi: https://doi.org/10.1016/j.epsl.2024.119070).
