Abstract

Three-dimensional geological modelling is a rapidly growing field of interest and application, both in research and industry. This lead to the emergence of new open-source codes , making 3D geological modelling more accessible to all. We present PZero, an open source software written in Python, created and developed by GECOS-LAB (github.com/gecos-lab) and now supported by the GeoSciences IR project (geosciences-ir.it). PZero is a 3D geological modelling software with a user-friendly QT graphical interface designed for structural geologists, allowing for explicit and implicit interpolation (using LoopStructural) of geological structures drawn from different input datasets, including geological and structural field surveys, Digital Outcrop Models, and subsurface data such as wells and seismics. One important development branch of PZero is focused on modelling strategies and interpolation algorithms for 3D modelling of complex ductile structures, such as refolded isoclinal folds and shear zones. For this task we have selected some case studies from the Penninic Domain of the Central and Western Alps, characterized by continental and oceanic units that were deeply involved in subduction- and collision-related tectonics, then exhumed and crosscut by late-stage brittle faults, resulting in very challenging natural laboratories, where the latest modelling strategies can be tested in depth.
