Abstract

In this study, Quaternary activities in the western section of the Ladar Fault, located in Khur County, Yazd Block, Central Iran, were examined. The results derived from processed and field data indicate that the Ladar Fault, as it extends westward into Khur County, plays a significant role in displacements and sedimentary changes, particularly in Quaternary deposits. Airborne magnetic data trace the fault lineaments to depths of up to 15 kilometers, revealing that this fault is of the basement-involved type. The Khur Fault, as a subsidiary branch of the Ladar Fault, crosses Khur County and impacts the underlying Cretaceous layers and Quaternary sediments, causing displacements and structural disruptions. These findings highlight the ongoing tectonic activity of the horsetail structures of the Ladar Fault and their crucial role in shaping the geological structures of the region. Additionally, the investigations demonstrate that the Ladar Fault has significant impacts on the region's geomorphology, resulting in notable alterations in drainage patterns and surface sediments. This study confirms that the tectonic activities of the Ladar Fault are ongoing and play a vital role in the geological and geomorphological changes in the area.
