Structural geology

The structural geology is the study of the processes by which the force S (taken as of the forced ) applied to the Roche S transform there the forms (qualified Structure S) and the fittings granular (of the microstructure S). The action of transformation is always a Déformation, which makes pass a rock whole of a structure to another. Two big families of deformed structures - rock having already sudden sufficient constraints to be deformed, is the very great majority of the rocks - that the geologists study are the Faille S and the fold S, but it exists about it the different one.

Among the studied processes of deformation, the principal ones are:

the rupture of the rocks (known as “fragile deformation”);
the crumpling;
the Plastic deformation of the rocks (known as “pénétrative deformation” or “ductile deformation”);
the Rheology of the rocks;
the Microstructural of the minerals, which studies the deformation of the minerals during their growth .

The results of a structural study find their application in the comprehension of the Tectonique of an area. Structural geology thus is often taught within the framework of the Plate tectonics .
