Intracrystalline deformation of calcite
, 1991 It is well established from observations on natural calcite tectonites that intracrystalline plastic mechanisms are important during the deformation of calcite rocks in nature. In this thesis, new data are presented on fundamental aspects of deformation behaviour of calcite under conditions where 'dislocation creep' mechanisms dominate.

Deep Underground Science and Engineering, EarlyView.A one‐dimensional diffusion‐based mass transport model was built using PHREEQC to highlight the potential challenges posed by thermochemical sulfate reduction (TSR) in depleted gas fields. The results obtained indicated that the presence of iron minerals (pyrite and hematite) is crucial for H2S generation through TSR reactions.

Deep Underground Science and Engineering, EarlyView.The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...
