Major Tectonic Systems

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

Hourly volumes:

CM: 9:00 a.m.

Practical Training: 12:00 p.m.

Land: 6 hours

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

This module is closely related to endogenous petrology (HAT510T)

This module will be a prerequisite for the Geodynamics course (HAT606T) and the two L3 fieldwork courses (Deep-Earth Fieldwork (HAT517T) and Fieldwork (HATHAT614T)), in which more advanced concepts will be discussed.

 Second-year undergraduate courses, including HAT306T, HAT302T, HAT301T, HAT409T, HAT402T, and HAT405T

Recommended prerequisites: none
