DETAILED BRITTLE TECTONIC ANALYSIS OF THE LIMESTONES IN THE QUARRIES NEAR VAPENNA VILLAGE (CASE STUDY)

This paper describes limestone body situated in the northern part of the Branna group near Vapenna village in Javornik area. The body is confined by two major tectonic zones of this area - Sudetic Marginal Fault on the east and Ramzova overthrust on the south. Detailed tectonic analysis has been performed in two big limestone quarries named quarry I and II. Strikes and dips of fault planes and joints were measured. In the quarry I just one important orientation of the fault planes was found - W-E mostly vertical. In the quarry II two main fault plane orientations were observed - vertical NW-SE Sudetic and NE-SW Moravo-Silesian. The senses of movements in the fault planes were determined using the calcite steps mainly as the kinematic indicators. Presence of the kinematic indicators allowed performing of paleostress analysis. Several different tectonic phases were identified and discussed.
