It is desirable to incorporate heuristic and empirical knowledge including hydrological and bio-geochemical considerations into the selection process of a potential landfill site. In this paper, a prototype expert system for the selection of a landfill site, with hybrid knowledge representation approach under object-oriented design environment in a blackboard architecture, is described. It inco...

For evaluation of the mineral potential of Sirutr area in the north east of Khorasan, 140 stream sediment samples were analyzed for Ni , Co, Ag, Sb, Hg and Au. Results of these analyses ind ica te an unusual assay for most of these elemen ts, especia lly for gold a nd ant imony. Statis tical analyses and co mparison of geologic map with the surrace anomaly maps indicate a posit ive re lat...

Present research deals with the representative groundwater sampling locations establishment for the geochemical evaluation of the subsurface aquifer systems of Rajnagar Block, Odisha along the east coast of India. The study looks into the hydrological, topographical and geological set up of the area to evaluate the natural influencing factors and the cultural set up of the human habitats and it...

The research was conducted at the Geothermal Company Energy Lx Area. area includes three well pads of geothermal power plants, namely X1, X2, and X3, which are stratigraphically composed quaternary volcanic rocks. Based on geochemical data pad, it shows that chloride type fluid is in equilibrium/partial equilibrium with reservoir temperature range 230 – 300°C from silica Na-K geothermometer ana...

anomaly recognition has always been a prominent subject in preliminary geochemical explorations. among the regional geochemical data processing, there are a range of statistical and data mining techniques as well as different mapping methods, which serve as presentations of the outputs. the outlier’s values are of interest in the investigations where data are gathered under controlled condition...

Iranian Cenozoic magmatic belt, known as Urumieh-Dokhtar, is recognized as an important polymetallic mineralization which hosts porphyry, epithermal, and polymetallic skarn deposits. In this regard, multivariate analyses are generally used to extract significant anomalous geochemical signature of the mineral deposits. In this study, stepwise factor analysis, cluster analysis, and concentration–...
