Fuzzy c- means cluster analysis, a robust multivariate technique in stream sediment geochemical exploration, a case study in Eastern part of Iran, Birjand

  Fuzzy c-means cluster analysis (FCMC) applied to the results of a geochemical exploration project where 175 stream sediment samples were analyzed for 20 elements, using X-ray Fluorescence Spectrometry (XRFS). The FCMC technique allowed to separate the dominant associations of lithologies and specified the background concentration for all lithotypes. It was found that the FCMC is a power tool for elimination...

Comparison of rock units separation and fuzzy logic methods in neutralizing the syngentic effects in geochemical data, a case study in eastern part of Iran, Birjand

  The elemental concentration variations in mineralization processes in the nature are mainly influenced by the syngenetic and epigenetic processes. By neutralizing the syngenetic effects, the epigenetic effects may delineate the mineralization of the interest elements. In the present study, two methods which were carried out in detecting the potential areas across the study area are compared; a) the...

Geoelectric investigation of groundwater in Obaretin – Iyanomon locality, Edo state, Nigeria

  Geoelectric investigation for underground water in Obaretin – Iyanomon and its environ was done using the Vertical Electrical Sounding (VES) method. Three vertical electrical sounding (VES 12, 14 and 28) data were acquired within the locations in the study area. Borehole data were also acquired. These were used in delineating the geoelectric sections. The study was carried out using the Schlumberger...
