3d Structural Analysis: Methods and Applications

The course aims to provide students with an integrated and advanced understanding of structural analysis, with a focus on the three-dimensional representation and interpretation of geological structures. Starting with the classic tools of structural analysis (e.g., vertical geological cross-sections, spherical statistics, fault kinematics, blasthesis-deformation relationships, folds and thrusts), the course guides students in applying these techniques to complex geological contexts for the reconstruction of subsurface geometries.

Special attention will be paid to the construction and interpretation of 3D geological models, integrating surface geological data (lithologies, layers, and structures) and geological cross-sections, using three-dimensional subsurface modeling software.

The principles of the relationship between deformation and rheology will be introduced through the use of numerical techniques.

The course is primarily taught in the classroom, with practical exercises on geological maps of varying scales and complexity, and digital modeling activities to develop geometric and spatial synthesis skills. A portion of land is also planned for the collection of geological data.

Upon completion of the course, students will be able to:

· Apply quantitative structural analysis techniques at different scales (micro-, meso-, and megastructural).

· Perform stress field inversion from structural data.

· Solve three-dimensional distribution problems for planar and linear geological data.

· Integrate surface and subsurface geological data to build and interpret 3D geological models.

· Use dedicated software for three-dimensional modeling of geological structures.

· Use numerical techniques to evaluate the influence of rheology on deformation.

· Prepare a comprehensive geological-structural report that includes 3D interpretations and a discussion of the proposed structural models.
