This study focuses on using multivariate analyses to generate semi-automated geological maps and exploration targets associated with porphyry Au-Cu mineralization within the Kassandra mining district, Greece. We use principal component analysis (PCA) self-organizing (SOM) reveal variations in geochemical magnetic signatures input datasets. visualize results as pseudo-geological reflecting proce...

Geological mapping in vegetation coverage areas is a challenging task. In this study, convolutional neural networks (CNNs) were employed for geological area based on remote sensing images and geochemical survey data. The Gram-Schmidt fusion technology was first applied to fuse Sentinel-2A ASTER enhance the spatial resolution enrich spectral information of fused then organically integrated with ...

Agricultural soil (Ap-horizon, 0–20 cm) samples were collected from 33 European countries as part of the GEMAS (GEochemical Mapping and grazing land Soil) soil-mapping project. The Mg data derived total concentrations (XRF) two acid digestion methods, aqua regia (AR) Mobile Metal Ion (MMI®), used to provide an overview its spatial distribution in at continental-scale. Magnesium is one most abun...

The most significant aspect of a geochemical exploration program is to define and separate the anomalous values from the background. In the past decades, geochemical anomalies have been identified by means of various methods. Most of the conventional statistical methods aiming at defining the geochemical concentration thresholds for separating anomalies from the background have limited the effi...

Geochemical anomalies are geochemical features different from what is considered normal. They can be the result of: 1. unusual or uncommon processes concentrating particular elements (e.g. an ore-forming process, weathering and element dispersion from an unusual element concentration such as an orebody); 2. element accumulation or concentration by common processes acting over long periods (e.g....

This study aims to handle an integrated evaluation of soil and stream sediment geochemical data evaluate source apportionment establish threshold variations for Fe, Al, 20 selected Potentially Toxic Elements (PTE) in the Parauapebas River Basin (PB), Eastern Amazon. The set used this is from Itacaiúnas Geochemical Mapping Background Project (ItacGMBP), which collected 364 surface (0–10 cm) samp...

Geochemical and geophysical observations for large-scale structures in the Earth’s interior, particularly horizontal variations of long wavelengths such as degree-1 degree-2 structures, are reviewed with special attention to cause hemispherical mantle structure. Seismic velocity, electrical conductivity, basalt geochemistry used mapping discuss thermal compositional heterogeneities their relati...
