Abstract Research on quantum sensors for the detection of magnetic fields (quantum magnetometers) is one fast-moving areas Quantum Technologies. Since there exist expectations about their use in geophysics, this work will provide a brief overview various developing technologies and individual state art implementing magnetometers. As example, developments superconducting interference devices, so...

The search for hidden minerals with a large, buried depth depends on the guidance of geological and metallogenic theory, but it is difficult to master characteristics deep deposits. In this paper, taking survey area as an example, stimulated polarization geophysical method used obtain information indirectly. Through analysis study IP (induced polarization) anomaly its in tin polymetallic mining...

Eucalyptus trees may translocate Au from mineral deposits and support the use of vegetation (biogeochemical) sampling in mineral exploration, particularly where thick sediments dominate. However, biogeochemistry has not been routinely adopted partly because biotic mechanisms of Au migration are poorly understood. For example, although Au has been previously measured in plant samples, there has ...

The risks of developing mineral resources need to be known as accurately as possible. This process should start at the exploration stage and continue through feasibility to the development stage. Until recently, this type of analysis was carried out manually, leading to subjective judgments. Many mining companies have built up extensive exploration geological databases, which represent signific...

Imaging spectroscopy is a widely used tool in mineral exploration today where exploration companies offer the full service package to their clients: (data acquisition, preprocessing and product delivery). These exploration projects rely mainly on airborne imaging spectrometers such as Hymap, AISA or HySpex. This data is usually scarce and expensive and may not be available to academic research....

Singularity based on fractal and multifractal is a technique for detection of depletion and enrichment for geochemical exploration, while the index of vertical geochemical zonality (Vz) of Pb.Zn/Cu.Ag is a practical method for exploration of blind porphyry copper mineralization. In this study, these methods are combined for recognition, delineation, and enrichment of Vz in Jebal- Barez in the s...
