Abstract

Taleghan area due to existence of fracture zones, active faults, seismicity, and geological features is potentially an unstable region. Study of LINEAMENTs due to their significance in conducting surface water and also as a LANDSLIDE controlling factor is very important in such area. In this research LANDSLIDE inventory map was produced based on aerial photo interpretation and field investigation in a geographical information system (GIS).Image processing of TM data was performed by applying gradient filters in four directions. (NW-SE, NE-SW, E-W and N-S), and LINEAMENT layers were extracted. Relation between LANDSLIDE frequency and distance from LINEAMENTs, and also LANDSLIDE frequency and LINEAMENT frequency were obtained.On the other hand, the relation between LINEAMENT directions and the main geological structures such as faults and folds were studied. The results indicated that: 1- In general, LINEAMENT directions follow geological structural feature in the study area. 2- The result indicates good agreement among landsliding and LINEAMENT density as well as distance from LINEAMENTs. 3- LINEAMENTs with NW-SE direction are well correlated with predominant of fault directions and fold axis. 4- LANDSLIDEs in the area are closely related with NE-SE LINEAMENTs. The research indicates the capability of remotely sensed data and GIS for recognition and analyses of LINEAMENTs which play important role in recognition of new geological structures responsible for landsliding in TALEGHAN area.
