Major tectonic systems

This course unit aims to describe, based on relevant tectonic observations at different scales, the functioning of major tectonic systems: folded systems, thrust faults, large normal faults, ductile shear zones, detachment domains, extensional domains, and more complex domains. Particular attention will be paid to regional case studies (France, United States, Tibet-Himalayas).

Hourly volumes:

CM: 9 a.m.

Practical work: 12 hours

Field: 6 hours

The main objective is to provide basic skills in tectonics, i.e., in the analysis of large-scale deformation (km).

This module has strong links with endogenous petrology (HAT510T).

This module will be a prerequisite for the Geodynamics course (HAT606T) and the two L3 field courses (deep field course (HAT517T) and field course (HATHAT614T)), in which more advanced concepts will be discussed.
