Using the potential landslide hazard zonation, areas with high potential of landslide hazard can be detected and so prevent the landslide occurrence with providing appropriate solutions. In this study, the landslide hazard zonation along the water transmission lines of the Amir-Almomenin (AS) water supply complex has been done. Studied area is located at the western part of the Northern Khorasan (Bojnord). Study procedure includes the general geology survey, recognition of the most important effective parameters on the landslide phenomena (such as slope, lithology, faults and streams) and has been evaluated as basic maps. Then, each layer was validated based on the importance of the effective factors using the maps weighting method in ArcGis software. Finally, the studied area was zoned based on the landslide potential using the overlapping of the various layers. Final zonation map shows that the North, Northwestern and Median parts of the studied area have the highest landslide potential. These areas are included of Marl and red Marl and to some extend loss deposits with slopes between 14 to more of 50 degrees. Seemingly, faults (due to low occurrence) and streams (due to drought) have lower effect on the landslide potential. However, the degree of the slope and type of lithology are the most important parameters on the landslide potential, respectively.展开更多

This region is part of central Iran, which is of high significance due to existence of metal and non-metal deposits. Considering the location of the study area, the lithology and metal-mineral indices of Dolat-Abad sheet, it can be said that their metallic deposits are economically feasible. Hence, this region is considered promising for exploration of metallic deposits. In order to achieve this goal, at first, the region’s alterations were detected by using OLI-ASTER images in ENVI software. After processing the lithogeochemical data in SPSS and GIS software, anomaly map of studied elements was obtained. Using geological map, different layers such as lithology, faults and indices were obtained. Eventually, by preparing the layers and incorporating those using the index overlay GIS modeling, promising mineralization areas in the region were identified. Results show that a significant Cu-Au mineralization has occurred in the south western region of the study area.展开更多

Balochistan super basin is subdivided into northern Balochistan (Pishin basin or Kakar Kohorasan basin represented as back arc basin), central Balochistan (Chagai-Raskoh-Wazhdad Magmatic arc and Hamuns-Inter arc basin) and southern Balochistan (Makran Siahan basin) basins. Balochistan basin consists of Cretaceous to recent sediments, diverse igneous rocks and low grade metamorphics. Balochistan basin is a leading basin which consists of very significant mineral deposits especially copper and gold deposits. These mineral resources need to be developed for the development of areas, province and Pakistan. During previous half century a lot of geological work has been done in Balochistan basin. Here the revised stratigraphic set up and its mineral resources with an update are being presented.展开更多
