The Piauí laterite (NE Brazil) was initially evaluated for Ni but also contains economic concentrations of Co. Our investigations aimed to characterise the Co enrichment within deposit; by understanding mineralogy we can better design mineral processing target recovery. is heterogeneous on mineralogical and lithological scale differing from classic schematic profiles nickel laterites, while the...

Imidacloprid is a systemic insecticide effective in controlling the exotic pest (hemlock woolly adelgid) in eastern hemlock () trees. Concerns over imidacloprid impacts on nontarget species have limited its application in southern Appalachian ecosystems. We quantified the movement and adsorption of imidacloprid in forest soils after soil injection in two sites at Coweeta Hydrologic Laboratory ...

Accurate determination of denudation rates is important in understanding Earth surface system dynamics. In situ produced cosmogenic nuclides, such as Be and Al, provide a valuable insight but are not entirely free from complications. In this study, denudation rates are determined for the Abukuma Mountains, Japan, using both site-specific and basin-scale methods. Considered with density measured...

[1] Reactive transport modeling is often used in support of bioremediation and chemical treatment planning and design. There remains a pressing need for practical and efficient models that do not require (or assume attainable) the high level of characterization needed by complex numerical models. We focus on a linear systems or transfer function approach to the problem of reactive tracer transp...

Soil-covered upland landscapes are common in much of the habitable world, and our understanding of their evolution as a function of different climatic, tectonic, and geologic regimes is important across a wide range of disciplines. Erosion laws direct quantitative study of the processes shaping Earth’s surface and form the basis of landscape evolution modeling, but are based on limited field da...

Late Quaternary rates of apparent soil production, bedrock incision, and average erosion are determined for the southeastern highlands of Australia using in situ produced cosmogenic nuclide concentrations of Be and Al. Apparent soil production rates define a steep, inverse exponential function of soil depth with a maximum of 143mMa 1 under zero soil depth. There were no observed soil depths bet...

Cobalt demand is increasing due to its key role in the transition clean energies. Although main Co ores are sediment-hosted stratiform copper deposits of Democratic Republic Congo, also a by-product Ni–Co laterite deposits, where extraction efficiency depends, among other factors, on correct identification Co-bearing minerals. In this paper, we reported detailed study mineralisation profiles Lo...
