Quantifying texture for acid rock drainage characterisation and prediction by Guseva, Olga

“…Recommendations for future work include: the quantitative assessment of the ARDI for meso-scale material; the assessment of detailed characterisation and prediction test leachate chemistry; trace element assessment and deportment throughout UCT batch biokinetic and humidity cell testing; mineralogical and textural assessment on characterisation and prediction test residues during and after tests; an in-depth analysis of the minimal/optimal sample block/sub-sample mass required for minimal error; the assessment of samples using X-ray microcomputed tomography to assess and decrease the effects of stereological bias prevalent in 2D measurements; and the application of a similar texture and mineralogy assessment to additional waste types (such as coal wastes, or waste material containing non-Fe-bearing sulfides).…”

Using high resolution Sr isotope data from the Nama Group, South Africa, to constrain global stratigraphic relationships and continental weathering rates in the terminal Ediacaran by Mtonda, Mcdonald Takondwa

“…To ensure that the 87Sr/86Sr ratios generated in this study were reflective of primary seawater signals, a sequential leaching procedure, first proposed by Bailey et al., (2000), was tested on Ediacaran bulk rock carbonate samples. The successful implementation of the sequential digestion technique was verified through careful examination of samples for diagenetic alteration using petrography, trace element ratios and  18O. …”

A geochemical study of metasomatised peridotite and marid nodules from the Kimberley pipes, South Africa by Waters, Frances Gillian

“…The behaviqr of Ba appears to have been different in the two sources/fluids - the deeper-derived fluids produced Ba-rich phlogopites, whereas the MARID magmas and MARID-derived fluids resulted in the formation of Ba-poor phlogopites in MA.RID and PKP rocks. Modelling of fluid compositions using published crystal/melt and crystal/fluid partition coefficients and PKP mineral trace element abundances is inconclusive but suggests that the MARIDderived fluids (and possibly the deep-derived fluids as well), were strongly LREE-enriched with REE patterns comparable to lamproites or kimberlites, and with moderately high Rb and Ba contents. …”
