Major tectonic systems

The aim of this course is to use relevant tectonic observations at different scales to describe the functioning of major tectonic systems: folded systems, thrusting, large normal faults, ductile shear zones, unstripping domains, extensive domains and more complex domains. Particular attention will be paid to regional case studies (France, USA, Tibet-Himalaya).

Hourly volumes :

CM :9h

Practical work:12h

Field :6h

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

This module has a strong link with endogenous petrology (HAT510T)

This module will be a prerequisite for the Geodynamics UE (HAT606T), the two L3 field placements (deep-domain field placement (HAT517T) and field placement (HATHAT614T)) in which more advanced concepts will be discussed.

 Licence 2, including HAT306T, HAT302T,HAT301T,HAT409T,HAT402T,HAT405T

Recommended prerequisites: none

Integral Continuous Control

• Synthetic description of the concepts covered in CM :

Each class is 1.5 hours long, i.e. 6 classes for a total of 9h.

CM1: Analysis of finite deformation (large deformation)

CM2: Incremental deformation and finite deformation, stress-strain relationship, notion of rheology

CM3: Major folded systems

CM4: Large overlapping systems

CM5: Large-scale extensive systems

CM6: Large stalling systems

• Synthetic description of TP sessions and number of hours associated with each session

Each practical course is 3 hours long, i.e. 4 practical courses for a total of 12 hours.

TP1: Rotational and shear deformation

TP2: Observations of ductile shear zones

TP3: Folding and overlapping

TP4: Fault analysis and inversion
