Journal ArticleDOI
TL;DR: In this article, the age distribution of detrital zircon U-Pb was found to correspond to the ages of prominent crustal components within the respective cratons.

Journal ArticleDOI
TL;DR: Re-processing of primary Cu slags for metal recovery, and subsequent co-disposal of the resulting slag tailing with dolomite-rich mine tailing and local laterite is suitable for stabilizing the remaining contaminants (except Sb) and limiting their leaching into the environment.

Journal ArticleDOI
TL;DR: In this article, the authors studied the lower Cambrian Naukluft Thrust which crops out in central Namibia and found that it contains a cataclastic dolomite fault rock, referred to as "gritty dolomerite" which they interpret as a signature of coseismic carbonate dissociation and subsequent fluid-rock interactions.

Journal ArticleDOI
TL;DR: The exposure estimates calculated for an adult person of 70 kg at a dust ingestion rate of 50 mg/day indicated that As, Pb (and also Cd to a lesser extent) grossly exceeded tolerable daily intake limits for these contaminants in the case of slag and smelter dusts.

01 Aug 2017-Geoderma
TL;DR: In this article, the authors studied Fe-Mn concentric nodules from Cutanic Luvisol in the northern part of Namibia, where agricultural fields are irrigated with the drainage water from the Kombat Cu-Pb-(Zn) mine (pH 7, metal concentrations in μg l − 1 : Fe 7, Mn 10, Zn 7, Cu 18).

Journal ArticleDOI
TL;DR: The concentration of heavy metals in several sites, assessed in water, soil and sediment samples, affected by different pollution sources are reviewed, showing how human activities impact natural media and how the pollution spreads.

Journal ArticleDOI
TL;DR: A review of the available prevention of acid mine drainage generation, treatment options and their importance in light of the future perspectives are briefly discussed in this paper, where the possible resources to be recovered such as ferric hydroxide, ferrite, rare earth metals, sulphur and sulphuric acid and their economic benefit are discussed.

Journal ArticleDOI
TL;DR: In this paper, a review summarizes over 160 studies focused on soil contamination near non-ferrous metal smelters, with an emphasis on the combinations of traditional geo-chemical approaches with various mineralogical and metal isotope techniques that are particularly helpful for depicting the fate of smelter-derived contamination in the soil.

TL;DR: In this article, the authors developed kinematic models of the spatiotemporal evolution of slip over the seismic cycle and to determine the budget of seismic and aseismic slip.
Abstract: Understanding the partitioning of seismic and aseismic fault slip is central to seismotectonics as it ultimately determines the seismic potential of faults. Thanks to advances in tectonic geodesy, it is now possible to develop kinematic models of the spatiotemporal evolution of slip over the seismic cycle and to determine the budget of seismic and aseismic slip. Studies of subduction zones and continental faults have shown that aseismic creep is common and sometimes prevalent within the seismogenic depth range. Interseismic coupling is generally observed to be spatially heterogeneous, defining locked patches of stress accumulation, to be released in future earthquakes or aseismic transients, surrounded by creeping areas. Clay-rich tectonites, high temperature, and elevated pore-fluid pressure seem to be key factors promoting aseismic creep. The generally logarithmic time evolution of afterslip is a distinctive feature of creeping faults that suggests a logarithmic dependency of fault friction on slip rate...

Journal ArticleDOI
TL;DR: In this article, the authors review the criteria for seismic slip defined by Cowan and determine that they are too narrow, and conclude that seismic slip at rates in the range 10−4−101 ǫm/s is almost certainly dynamic.
