TY - CONF ID - 1181616 AU - Knížek, Martin - Melichar, Rostislav PY - 2014 TI - The Clay and Závist faults – one large strike-slip fault in the east part of Barrandian (Bohemian Massif) KW - Barrandian KW - Závist Fault KW - Clay Fault KW - strike-slip fault KW - stratigraphy fault-cut diagram N2 - The Clay and Závist faults are connected one another not only by the same direction but also by continuous change of their dip. The Clay Fault gradually changes its steep dipping to NW on the SW to subvertical orientation on the NE. Here, near Dobříš town, Závist Fault continuously varies analogously from subvertical position (on SW) to medium dipping to the SSE on the NE. It is obvious, that both faults are forming one single structure, whose surface is screwed into form of propeller. Construction of stratigraphy fault-cut (SFD) diagram was used to testify, whether faults movements are compatible (Fig. 1). Cross-cutting fault-cut lines indicate partially rotational nature of movement along the unified fault surface. The axis of rotation is projected to place near Dobříš town, where both walls of the fault take place in the Proterozoic sediments. Shared activity of both faults corresponds to sinistral strike-slip movement with a slight rotation producing different components relating to distance from rotational axis. As the main phase of tectonic movement is partly synchronous with granodiorite intrusion, we assume the Tournaisian and Visean age of tectonic activity along the fault. ER -
