Abstract Soil geochemical prospecting is becoming an increasingly important part of archaeological research. Therefore, it possible to determine the location various facilities that no longer exist in study region. In this study, a morphological analysis “Stara Góra” deposit Radzimowice (Lower Silesia, Poland) was performed using LiDAR DTM (light detection and ranging digital terrain model) ima...

Mapping of carbonatites and related mineral deposits has occupied prominent place in resource exploration programs given their potential to host valuable concentrations critical metals such as rare earth elements niobium. Based on spectral characteristics most indicative minerals for these rocks, a mapping approach was developed using Advanced Spaceborne Thermal Emission Reflection Radiometer (...

A fundamental challenge in modern mantle geochemistry is to link geochemical data with geological and geophysical observations. Most of the early geochemical models involved a layered mantle and the concept of geochemical reservoirs. Indeed, the two layer mantle model has been implicit in almost all geochemical literature and the provenance of oceanic island basalt (OIB) and mid-ocean ridge bas...

Discrimination of the blind and dispersed mineralization deposits is a challenging problem in geochemical exploration. The frequency domain (FD) of the surface geochemical data can solve this important issue. This new exploratory information can be achieved using the interpretation of FD of geochemical data, which is impossible in spatial domain. In this research work, FD of the surface geochem...

The surface geochemical response to bedrock containing elevated levels of the platinum group elements (PGE) is commonly so subtle that standard geochemical methods are insufficiently sensitive to assist the exploration geologist. At the Geological Survey of Canada, recent research on analytical methods by one of us (GEMH) has been directed toward the development of a selective leach of soils an...
