Abstract

A vein-type barite deposit is occurred along the Behjatabad fault zone in Lower Cretaceous carbonates in the eastern part of Murchekhurt. In order to assess the rational relationship between structures and vein-type barite mineralization in the east of Murchekhurt area, remote sensing analysis on the satellite images with the aim to identify the structures have been done, then faults, veins and bedding have been measured in the fieldwork. The main structures are the deep basement northern and southern Behjatabad fault zone in the eastern part and the Sepahan fault zone in the western part of the study area which hosts the vein-type barite mineralization. Those fault zones show an old reverse kinematics associated with drag folds and a young right-lateral strike-slip sense of movement that is still active. Paleostress analysis documents a shift in the stress regime from NE-SW-directed to N-S-directed since the middle Miocene. Spatiality the Behjatabad fault zone is close to UDVA and acted as a dip corridor for conducting Ba-bearing hydrothermal fluids and hosting the barit mineralization.
