Progress in understanding mineral evolution, Earth’s changing near-surface mineralogy through time, depends on the availability of detailed information on mineral localities of known ages and geologic settings. A comprehensive database including this information, employing the mindat.org web site as a platform, is now being implemented. This resource will incorporate software to correlate a ran...

This study conducts an empirical analysis of the effects procedure transforming digital on natural resource rents in private and public sectors. In our paper, we analyze changes total (rents from coal, mineral, gas, forest) by businesses (e-commerce, involving shopping online, turnovers e-commerce, trading e-commerce web, business electronically, use customer relationship management (CRM), clou...

Mineral dust is a contributor of the global aerosol budget, with arid regions as principal sources. IPCC (2007) gives a best estimate of the direct mineral dust radiative forcing (RF), with the highest uncertainty in the radiative balance estimations being associated to mineral dust for both its direct and indirect effects. In addition, differentiating the anthropogenic influenced dust has impo...

We study the economic implications of mineral resource activity for non-mining regions at grid-level across African continent. find that capital cities benefit from anywhere in country. Leaders’ birth also benefit, but only autocratic regimes. Generic regions, on other hand, are worse off. These results suggest regional redistribution rents Africa is primarily undertaken to and leaders’ regions...

The prerequisite of maintaining an efficient and safe mining operation is the proper design of a mine by considering all aspects. The first step in a coal mine design is a realistic geometrical modelling of the coal seam(s). The structural features such as faults and folding must be reliably implemented in 3D seam models. Upon having a consistent seam model, the attributes such as calorific val...
