Overview: Raman spectroscopy is ideally suited for planetary exploration, because Raman spectra provide detailed molecular and structural information, very useful for geochemical measurements as well as to measure organic and inorganic biomarkers in the search for past or present life on other planets [1]. Raman scattering, a very weak process, can be relatively strong at deep UV wavelengths be...

The geochemical characteristics of a near shore inland aquifer system have been investigated in the Coastal Aquifer Test Field (CAT-Field) between Bremerhaven and Cuxhaven in the Northern Part of Germany which is described by Kessels et al.(this issue). Groundwater and sediment samples from the aquifer were taken at different locations on the flank of a glacial channel at depths between 5 and 1...

Regional exploration and identification of anomalies can be done by geochemical data resulted from stream sediments. In this paper, fractal methods of concentration-number and concentration-area were used for regional studies, and abnormalities of elements including gold, arsenic, bismuth and mercury were studied. Statistical processing of these elements took place with the help of 1063 samples...

Motivated by the recent successful results of using GIS modeling in a variety of problems related to the geosciences, some knowledge-based methods were applied to a regional scale mapping of the mineral potential, special for Cu-Au mineralization in the Feyz-Abad area located in the NE of Iran. Mineral Prospectivity Mapping (MPM) is a multi-step process that ranks a promising target area for mo...

The basic differences between the application of till geochemistry in Finland and Canada are that (1) there is far less integration of glacial geology and geochemical exploration in North America than in Finland and (2) the application of new glacial sedimentology models and examination of basic assumptions about the history and dynamics of Scandinavian ice sheets are less emphasized in Scandin...

jian cu deposit is hosted by surian volcano-sedimentary complex of permo-triassic age on the eastern edge of the sanandaj-sirjan metamorphic zone at a distance of 195 km from shiraz, southwestern iran. the complex consists mainly of metabasalt, chlorite-quartz schist, chlorite-muscovite schist, mica schist and graphite schist. pyrite is the most important sulfide and chalcopyrite is the major c...

in order to assess the potential of copper mineralization and its associated elements in soltan meydan basaltic formation situated in the north of shahrud, the method of stream sediment and heavy mineral has been used. to achieve this aim, totally 68 samples of sediments (-80 mesh in particle size) and 6 samples of heavy minerals (-20 mesh in particle size) have been collected in an optimized n...
