The Rocklea Dome is an area located on the western horn of Australia, and is a volcano-sedimentary formation linking the Pilbara Craton and all-Archean sediments in an oceanic extension mechanism. The goal of this project is to understand the history of the area, then to study the drilling data made by Murchison Metals Ltd. with the tools of the python library developed by DeepLime, and to use this experience to perfect these tools and the guides made available by the company.
