| The Krušné Hory Mountains fault is undoubtedly one of the basic building blocks of the Eger Graben, because it forms its NW edge fault and its course consistently correspond to the geometry and deep structure of this higher-order volcano-tectonic structure (Fig. 2). According to the basic idea of the development of the Ohře rift (Kopecký L. 1987), the Krušné hory fault played a subordinate role in the initial and main volcanic phases, and its more significant revival did not occur until the end of the Neogene or the Quaternary (cf. Elznic et al. 2010). | The Krušné Hory Mountains fault is undoubtedly one of the basic building blocks of the Eger Graben, because it forms its NW edge fault and its course consistently correspond to the geometry and deep structure of this higher-order volcano-tectonic structure (Fig. 2).

| The second significant feature of the Krušné hory fault in the North Bohemian Basin are changes in its direction. Malkovský (1979) defines 4 basic sections according to the direction of the fault: between Litvínov and Střelná the fault has the direction NE - SW, between Střelná and Bohosudov the direction is E - W, between Bohosudov and Telnice the direction of NE - SW, and from Telnice to the east direction of E - W. It is noteworthy that the E - W direction acquires a fault where the subsoil is formed by granitoid rocks. | The second significant feature of the Krušné hory fault in the North Bohemian Basin are changes in its direction.

| More detailed characteristics of the breach in those parts of the fault where the fracture-free ejection is dominated are contained mainly in unpublished mining documentation. A published case is, for example, the work of Váně (1961), which describes the bending of a layer near Hrdlovka. The bend begins in the deepest part of the basin and from there in a section 1.5 km long, its slope gradually increases towards the Krušné hory slope up to 52 ° at the edge of the basin. In the bent part, the layer is significantly crushed (Malkovský 1985). | More detailed characteristics of the breach in those parts of the fault where the fracture-free ejection is dominated are contained mainly in unpublished mining documentation.
