Solid Earth Geophysics
A.Y. 2023/2024
Learning objectives
The course unit aims to deepen the knowledge of the physical mechanisms that regulate the dynamics of the deformation processes involving the crust-mantle system at small and large spatial and temporal scales.
Particular attention is devoted to the acquisition of the ability to physically model the deformation for a variety of geodynamic processes, such as intraplate deformation, subduction, extension and mantle convection, through the integration of the balance equations (conservation of mass, momentum and energy) and constitutive equations.

Course syllabus
THEORY: Rheology of the Earth, at different time scales. Constitutive laws. Elastic, Creep, Brittle, Plastic and viscoelastic deformation. Mass, energy and momentum conservation equations. Deformation energy function.
Prerequisites for admission
Good knowledge of the basic concepts of continuum mechanics.
Teaching methods
The lessons will take place in the classroom using the classic chalk blackboard and, only occasionally, by projecting powerpoints.
Teaching Resources
After each lesson, a pdf file, which contains an exhaustive presentation of the topics covered in class and which can be used as a text for the study, will be made available on the didactic web page accessible through the ARIEL portal.
Texts for further information:
G. Ranalli, Rheology of the Earth, Deformations and flow processes in geophysics and geodynamics.
D. Turcotte and G. Schubert, Geodynamics, Application of continuum physics to geological problems.
Several copies of both texts are available in the library of the Department of Earth Sciences "A. Desio".

Assessment methods and Criteria
The exam will take place in oral form and will be aimed at verifying the student's knowledge of the physical mechanisms that regulate the dynamics of the deformation processes involving the crust-mantle system on different scales, both spatial and temporal.
