3D Visualization of geological structures using Python: the case study of the Palomeque sheets (SE, Spain)

Abstract

The goal of this paper is the construction of computerized 3D visualization of geological structures. Several Python applications have been used to adapt the paper map-based geological classical information to numerical geological maps represented in HTML files. The models include a map with the stratigraphic and structural contacts and symbols, five serial vertical sections, and a geological block diagram, all with real topography. This block diagram made with 2D figures allows a 3D visualization. Palomeque area (Murcia region, southeastern Spain) has been used as a key-case. This area consists of a deformed Upper Cretaceous to Oligocene succession belonging to the Internal Zone Malaguide Complex. The main structure consists of two thrust-fold sheets forming an imbricate system, also affected by a set of strike-slip faults with a sinistral regime. The constructed maps show a good agreement with the published classical geological maps and cross-sections demonstrating the benefits of using these Python applications.
