Abstract

The Kharvana‒Zonouz Fault system with general NW‒SE trending right-lateral folds and strike-slip and reverse faults is located in NW Iran. This fault system could be considered as the southeastern continuation of the Nakhichevan‒Sardarapat Fault system in Azerbaijan toward NW Iran. Toward SE, the Kharvana‒Zonouz Fault system reaches to the active Qoshadagh Fault. The major faults in the Kharvana‒Zonouz Fault system from north to south are Kharvana Fault with dextral strike-slip movement, Estarkhan‒Komar Fault with reverse movement, Nahand Fault with dextral strike-slip and reverse movements and Zonouz Fault with dextral strike-slip movement. Dextral displacement in drainage pattern and occurrence of earthquakes show the activity of the Kharvana‒Zonouz fault system. Strike-slip faults almost parallel to the folds and reverse faults at the same rock formations could be evidence of transpressional tectonic regime within the Kharvana‒Zonouz Fault system.

Kharvana‒Zonouz活动断层系统：伊朗西北部超压构造政权的证据

摘要

Kharvana‒Zonouz断层系统位于伊朗西北部，具有一般NW‒SE向右褶皱，走滑和反向断层的趋势。该断层系统可视为阿塞拜疆NakhichevanicheSardarapat断层系统向伊朗西北部的东南延伸。朝东南方向，Kharvana‒Zonouz断层系统到达活动的Qoshadagh断层。从北到南的Kharvana‒Zonouz断层系统的主要断层为右旋走滑的Kharvana断层，逆向运动的Estarkhan‒Komar断层，右旋走滑和反向运动的Nahand断层和右旋走滑的Zonouz断层运动。排水模式的右移和地震的发生表明了Kharvana‒Zonouz断层系统的活动。
