GEOLOGICAL SECTIONS II
Learning outcomes of the course unit
The course prepares the Student to understand and interpret the three dimensional geometries of geological bodies and deformation structures represented on geological maps. Exercises will train Students to represent these geological bodies and structures in two dimensions (cross-section) and to define their geometries before deformations (balanced cross-section). Computer skills will also improve.
Knowledges of stratigraphy and structural geology.
