Abstract :
Mashhad plain is located in a specific structural location and is affected by a group of active faults in north of the Binalood mountain, sothern margin of Kope-Dagh mountain and Bakharden – Quchan Fault System in west. Activity of these faults shaped the En echelon morphology of bedrock plain. Also function of active faults in quaternary period affected the thickness and expansion of alluvial sediments with high potential of water flow rate. Tous fault as an accessory branch of Kashafroud fault zone in North of the Mashhad plain, plays an important role in controlling the behavior of groundwater reservoir in this plain. Based on a combination of geoelectric profiles and instrumental excavation results, the Tous Fault is discovered as a subsidiary and leading fault, with the Fault-Propagation Folds mechanism developing without subsurface outcrop under a series of anticlines north of Mashhad plain.
