Space or climate? Disentangling cosmogenic and climatic drivers of present-day tritium (3H) in global precipitation

Autor: Stefan Terzer-Wassmuth, Luis J. Araguas-Araguas, Lorenzo Copia, Jodie A. Miller

The generation of cosmogenic tritium (3H) through spallation of 14N in the upper atmosphere and a its decay (half-life of 12.32 y) are the two main processes resulting in the global steady-state inventory of tritium in the hydrosphere of approximatel

X-ray computed tomography: Practical evaluation of beam hardening in iron ore samples

Autor: I.J. Basson, Megan Becker, Jodie A. Miller, Lunga C. Bam

Publikováno v: Minerals Engineering. 131:206-215

X-ray computed tomography is a non-destructive 3D analytical technique, which in recent years has gained more widespread applications to characterise the internal structure of materials in minerals processing and metallurgical studies. Successful app

Combining quantity and quality controls to determine groundwater vulnerability to depletion and deterioration throughout South Africa

Autor: Jodie A. Miller, Andrew Watson, J. D. van Rooyen

Publikováno v: Environmental Earth Sciences. 79

Groundwater vulnerability is normally associated with the potential for contamination, for example the DRASTIC approach, but the increasing importance of groundwater in human, agricultural, and industrial systems, implies that groundwater vulnerabili

Recharge Estimation Using CMB and Environmental Isotopes in the Verlorenvlei Estuarine System, South Africa and Implications for Groundwater Sustainability in a Semi-Arid Agricultural Region

Autor: Jodie A. Miller, Andrew J. Watson, Anya Eilers

Publikováno v: Water
Volume 12
Issue 5
Water, Vol 12, Iss 1362, p 1362 (2020)

Groundwater recharge remains one of the most difficult hydrogeological variables to measure accurately, especially for semi-arid environments where the recharge flux is much smaller than in humid conditions. In this study, groundwater recharge was es

Minerals
Volume 10
Issue 4

Mineral textural quantification methods have become critical in both geosciences and mineral processing as mineral texture is a critical factor contributing to ore variability. However, the lack of objective mineral texture classification has made qu
