Some problems with the tectonic subdivision schemes application in field work – an example of the Western Sredna Gora subzone

Abstract

The tectonic subdivision is a regional method for correlation, very subjective and not always applicable during the field work. Usually, more detailed field investigations do not confirm the regional tectonic schemes, main characteristics of the tectonic units and boundaries. The given example for the Western Srednogorie subzone represents the handicaps of tectonic schemes fields application.
