Geological engineers have mostly been involved in geotechnical problems since the beginning of 19 century. Engineering geological maps and field data are needed to solve these problems. The amount of data for these maps is extremely large, so putting all the map elements on the map sheet causes difficulties while solving problems. The magic words, Geographic Information System (GIS) is a tool f...

abstract a major part of iran includes mountain areas. one of the hazards which threaten these areas is the slope instability. each year the occurrence of this phenomenon causes a lot of damages to the slope lands which are exploited by man. one of the most lot hazardous of these instabilities is landslide. the goal was to investigate the causes of this process and the methods of its stabilizat...

geographic information and analysis provide a wide range of data and techniques to monitor and manage natural resources. as an important case, in arid and semi-arid areas, water management is critical for both local governance and citizens. as a result, the estimation of water potential brought by snowmelt runoff and rainfalls seems to be very useful and important for these areas. hydrological ...

Production of Metallogenic-prognostic map (MPM) was preceded by the preparation of instructions that define three phases of work: preparation (with preparation of the Project), realization of field and laboratory research and data processing with production of different maps and, finally, production of the prognostic map with the accompanying instruction book. During the Project realization, th...

introduction identification of active tectonic areas, especially in convergent zone are very important because of their potential risks. nowadays, there are several algorithms that are used for tectonic analysis; one of them is tecdem that is used in this research. in this study, using remote sensing techniques, geomorphometric analysis and fieldwork were conducted to analyze morphometric and g...

Introduction: Quadrangle geological maps from Mariner 10 data cover 45% [1] of the surface of Mercury at 1:5M scale, e.g. [2],[3]. Orbital MESSENGER data, which cover the entire planetary surface, can now be used to produce finer scale geological maps, including regions unseen by Mariner 10. Hokusai quadrangle (0–90° E; 22.5–66° N) is in the hemisphere unmapped by Mariner 10. It contains promin...

This work describes a knowledge-guided clustering approach for mineral potential mapping (MPM), by which the optimum number of clusters is derived form a knowledge-driven methodology through a concentration-area (C-A) multifractal analysis. To implement the proposed approach, a case study at the North Narbaghi region in the Saveh, Markazi province of Iran, was investigated to discover porphyry ...

The program 'was designed to augment geological mapping and metalbgenic studies in the wea, conducted by Maclntyre et a / . (1987) and Maclntyre and Desjardins (I9XXa. h, unpublisted data). Their database and geological map were the starting points for the project. Geological mapping of the ncrthern part of the Babine Mountains Recreation Area, which was not included in the previous investi...
