Structural Zone

The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.

Structural Zone

an area of the earth’s crust, usually linear in form and characterized by a uniform structural plan and uniform tectonic deformations (for example, a fracture zone, a thrust zone, or a folded zone). Also distinguished are structurefacies zones and structure-formation zones, which, in addition, possess the specific features of the rock associations making up the zones (facies or formations). Each structural zone is an indicator of specific tectonic conditions under which the geological complexes making up the zone were formed.
