a gis-based weights-of-evidence model for mineral potential mapping of hydrothermal gold deposits in torbat-e-heydarieh area

چکیده
the method of weights of evidence is one of the most important data driven methods for mineral potential mapping in gis. in this method, considering the characteristics of known mineralized locations, we can prospect new mineralized areas. in this research work, the method of weights of evidence has been used for hydrothermal gold potential mapping in torbat-e-heydarieh area, east of iran. as a relatively large number of gold mineral occurrences (i.e., exactly 27 known gold mineralized locations) have been recognized in the study area, the use of the weights of evidence method for prospecting new gold mineralized zones in the area may be quite efficient. in this study, a combination of the results of the airborne geophysical, geological, argillic, propillitic and iron oxide alteration, geochemical and structural data based on the method of weights of evidence, has been made to determine probable gold mineralization zones in the form of a posteriori map of the survey area. consequently, four major zones in this area have been identified as high gold mineralization potential zones, in which many vein and veinlet mineralization forms can be found.

Groundwater resource is a very important water resource that has stable temperature, clear, tidy and confident. In recent years, population growth, industrialize and need to food and water, have exposed the groundwater resource on the risk. Reduction of water resources is a main problem in throughout the world. In this research groundwater potential mapping was obtained in Norabad plain, Lorest...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Hydrothermal Gold Mineralization and Some Features of Ore Mineral at Onzon-Kanbani Area, Central Myanmar
Onzon-Kanbani area is a western flank of Mogok Metamorphic Belt where gold mineralization is hosted as auriferous quartz-vein with epithermal low-sulphidation characters. Mineralization is closely associated with NE-SW trending fracture or shear zone probably related to the dextral movement of the Sagaing Fault system. Mineralization related hydrothermal alteration is developed as narrow zones ...

متن کاملGold Resources Potential Assessment in Eastern Kunlun Mountains of China Combining Weights-of-evidence Model with GIS Spatial Analysis Technique
Resources potential assessment is one of the fields in geosciences, which is able to take great advantage of GIS technology as a substitution of traditional working methods. The gold resources potential in the eastern Kunlun Mountains, Qinghai Province, China was assessed by combining weights-of-evidence model with GIS spatial analysis technique. All the data sets used in this paper were derive...
