Incorporating the uncertainty in geological boundaries into mineral resources evaluation
Geological modelling is a key step prior to grade estimation in a mineral deposit and consists of a deterministic partitioning of the deposit into sub-domains called 'geological units', each with relatively homogeneous ...
Evidence for a correlation between total lead concentrations in soils and the presence of geological faults
The emission of radon gas in regions of geological faults, during the radioactive decay of uranium and thorium, results in the formation of lead isotopes 210Pb, 208Pb, 207Pb and 206Pb. As a consequence, the lead contamination ...
