A study of anisotropy of magnetic susceptibility’s effectiveness in understanding palaeoflow systematics in shale basins
… flow direction. Each site was examined for its minerology; hysteresis tests were performed to observe if the source of magnetic susceptibility was from ferrimagnetic or paramagnetic minerals and to infer if the AMS reflected a grain or crystalline fabric. In the Ainsa case study, the samples had …

Advancement of fiber image guide based snapshot imaging spectrometer technology for bioimaging and environmental applications
… abiotic stressors such as water stress and soil minerology are presented. Design and implementation of components and housing will enable the snapshot imaging spectrometers to image dynamic targets in a variety of environments, including from an aerial platform. To enable miniaturization and high …

Mechanisms and management for soil carbon sequestration
… clear, and factors like litter chemistry and minerology can all come into play when determining the sequestration potential of a specific ecosystem. Additionally, not all soil C is equal in its turnover time or in its ability to resist disturbance. Therefore it is crucial that we better …

Duality of magmatism at Kirkland Lake, Ontario, Canada.
… magmatic domains defined by mode of emplacement, minerology and geochemistry. Mineral chemistry indicates that rocks from both suites evolved under oxidizing conditions in domains 1 and 3. Rare earth element compositions indicate a similar upper mantle source for both magmatic suites. Major …

Insights into the edifice stability of oceanic volcanoes from direct shear experiments and numerical models
… high friction (µ ≥ 0.6). The composition, minerology and rate-and-state friction however are highly variable between samples from the same and different volcanic edifices. Thus, whether a rock and subsequently a volcanic edifice might fail catastrophically highly depends on the individual …

Optimization of Phosphorus Removal and Mineral Characterization in Aerated Anaerobic Digestate with Divalent Cation Addition
… of pH, temperature, chemical choice and dose on minerology. A validated model could then be used to predict scaling potential and characterize minerals formed at WRRFs to better treat these nuisance scaling minerals and determine their potential for harvesting or sequestration as a nutrient-rich …

The geochemistry, mineralogy and igneous petrology of some fracture zone basalts from the southern Mid-Atlantic Ridge
The compositional variation in a suite of oceanic basalts dredged from a fracture zone transecting the Mid-Atlantic Ridge at 54°S is quantitatively evaluated in terms of fractional crystallization and crystal accumulation models. Bulk rock chemistry and petrography are used to classify the samples …

A detailed investigation into diamond-bearing xenoliths from Newlands Kimberlite, South Africa
This study involves a detailed investigation of diamond-bearing peridotite and eclogite from Newlands kimberlite, located on the Kaapvaal craton, South Africa. Eighteen peridotitic garnet macrocrysts (1 to 3 cm in size) containing diamond, and one with graphite, consist predominantly of lilac …

Model study of Tuyere erosion in refining
The erosion of Tuyeres in Refining has been studied in a Physical Model to establish the dependence upon injection conditions such as gas momentum and orifice profile.The erosion phenomena in terms of Mass transfer-mechanisms has also been studied.A coefficient of Mass transfer kc< , has been …

A study of alternative techniques to mercury amalgamation for gold extraction in artisanal and small-scale gold mining
… 38.0% for the 3 ores, respectively. Studying the minerology of the ores, using XRF, XRD, QEMSCAN, SEM-EDS and diagnostic leach, revealed the presence of sulphide minerals hosting refractory gold which contributed to the low gold extractions observed. Cyanide leaching proved to be a system that is …

Phosphorus fate and management on the Somerset Levels and Moors Ramsar ditch systems
… phosphorus (associated with iron and aluminium minerology) and higher total phosphorus levels, associated with algal and duckweed blooms. Thirdly, an investigation assessed the seasonal variation in spatial distribution and chemical fractionation of surface water phosphorus, as well as surface …

Characterization of lunar crust with moon mineralogy mapper data
This dissertation has three main focuses: (1) identify the distribution of a new rock type (Mg-spinel lithology) on the Moon and explore the likely petrogenesis of Mg-spinel; (2) investigate the presence of olivine in the crater central peaks and analyze the sources of olivine; (3) determine the …
