Mineral prospectivity mapping (MPM) based on the principle of geometric mean was applied to stream sediment geochemical, fault density, and aeromagnetic data from Tagmout basin, Morocco determine new areas for optimizing copper exploration. The application a fuzzy operator using data, factor analysis, density map, allowed weights be assigned these parameters so that MPM function can process the...

In gold (Au) exploration, the analysis of both bulk leach extractable (BLEG) and acid-extractable Au in <180μm stream sediment fraction are two most common approaches. The Eskişehir- Sivrihisar region Western Türkiye hosts several orogenic type mineral deposits. purpose this study is to delineate geochemical anomalies ore-related elements track their dispersion, which may lead discovery unknown...

A large regional geochemical data set of C-horizon podzol samples from a 188,000 km area in the European Arctic, analysed for more than 50 elements, was used to test the influence of different variants of factor analysis on the results extracted. Due to the nature of regional geochemical data (neither normal nor log-normal, strongly skewed, often multimodal data distributions), the simplest met...

-This paper presents the design and development of a Geochemical Expert System prototype (GES) for analyzing solution-mineral interactions in nature. The emphasis is placed on expert system design and knowledge representation. One of the most challenging and research-intensive steps was the identification of the key geochemical characteristics that would enable the expert system to identify sal...

An experiment was conducted with subsurface sediments from Oak Ridge National Laboratory to determine the potential for reduction of U(VI) under sulfate-reducing conditions with either ethanol or acetate as the electron donor. The results showed extensive U(VI) reduction in sediments supplied with either electron donor, where geochemical and microbiological analyses demonstrated active sulfate ...

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...

A range of bacteriological, geochemical process-related and molecular techniques have been used to assess the microbial biodegradative potential in groundwater contaminated with phenol and other tar acids. The contaminant plume has travelled 500 m from the pollutant source over several decades. Samples were obtained from the plume using a multi-level sampler (MLS) positioned in two boreholes (b...

Laser-Induced Breakdown Spectroscopy (LIBS) is a fast in-situ analytical technique based on spectroscopic analysis of atomic emission in laser-induced plasmas. Geochemical mapping at macroscopic scale using LIBS was applied to decimetric Zn-Pb ore sample from east Belgium, which consists alternating sphalerite and galena bands. A range elements detected with no or minimal spectral correction, i...
