Modern mineral exploration and extraction requires use of advanced technology and scientific methods. Mining today is to a major extent a high-tech industry and is going deeper. Successful deeper exploration will require more refined and accurate geological and geophysical models of the Earth's crust. In particular, the time dimension (4D) is important to understand. Methods need to be developed that rely on an array of data and measurements where high quality observations are merged to generate Earth models that can serve as a basis for new exploration strategies. We invite contributions dealing with all aspects of mineral belt modelling, including structural geology, rock mechanics, petrology, geochronology, isotope geology, mineral deposit studies, seismology, hydrology and exploration geophysics.
