Geochemical data are frequently collected from mineral exploration drill-hole samples to more accurately define and characterise the geological units intersected by drill hole. However, large multi-element sets slow challenging interpret without using some form of automated analysis, such as mathematical, statistical or machine learning techniques. Automated analysis techniques also have advant...

Detecting the mineralization component is one of the main subjects in geochemical exploration. Various techniques have been introduced to explore favorite zones and separate the anomaly from background, such as bivariate or multivariate statistical analysis. The main objectives is to identify the spatial variability and main sources of some special elements in Qare Char, in northwest of Iran, b...

Large-scale, high-density geochemical explorations entail enormous workloads and high costs for sample analysis, but, early mineral exploration, absolute concentrations are not essential. Geochemists require ranges, dynamics of variation, correlations rather than accuracy. Thus, higher work efficiency lower analysis desirable exploration. This study comprehensively analyzed the reliability appl...

Maximizing scientific return is critical to the success of space exploration. During SUBSEA project, which explored Sea Cliff vent site aboard E/V Nautilus as an analog for hydrothermal systems on Ocean Worlds, we used forward geochemical modeling guide decision-making during process Before expedition, performed 1670 reaction-path calculations simulate water-rock interactions circulation coveri...

rhis paper reviews geological, geochemical and ;eophysical data on the deeper parts of the high.emperature, water-dominated geothermal system of C’erro Prieto in Baja California, Mexico. It also ;peculates about the lithology, temperature, pressure and fluid chemistry that might be encountered in a jeep (about 6 km) exploration well being considered For the eastern part of this field. Based on ...

A significant example of technological spin-off from the GEOSTAR project is the special-purpose instrumented module, based on the deep-sea ROV MODUS, developed in the framework of the EU-sponsored project BIODEEP. The goal to be achieved has been defined as the exploration of the deep hypersaline anoxic basins of the Eastern Mediterranean Sea through real-time video images, measurements and acc...

Synthetic Aperture Radar (SAR) technology has the ability to image surface oil seeps that originate by slow leakage from oiland gas-filled traps. Multi-temporal satellite data over such seeps delineate prospective areas and provide the locations for follow-up surface sampling from which key geochemical information of the reservoir oil can be obtained. Satellite radar can offer the oil industry ...

A regional-scale stream sediment geochemical sampling was carried out with an averagesampling density of one sample per nine square-kilometre in Kiteto District, Manyara Region.A total 358 samples were collected and analysed for major traceelements by X-ray fluorescence (XRF) fire assay atomic absorption spectrometry(AAS) finish methods. In this study, Factor Principal Component Multivariate (F...
