Modelling microbial transport in simulated low-grade heap bioleaching systems: The hydrodynamic dispersion model
(Elsevier for Pergamon, 2017-07-08)The hydrodynamic model was developed to describe microbial growth kinetics within heap bioleaching systems. Microbial partitioning between the bulk flowing pregnant leach solution (PLS) and ore-associated phases that exist ... -
Granitoid zircon forms the nucleus for minerals precipitated by carbonatite-derived metasomatic fluids at Chilwa Island, Malawi
(Elsevier, 2017-07-27)Mineralogical assemblages are fundamental to the interpretation of geological processes. Zircon is an integral petrographic component of the mineral assemblages present in fenites (rocks formed by alkaline metasomatism) ... -
Cretaceous sea-surface temperature evolution: Constraints from TEX86 and planktonic foraminiferal oxygen isotopes
(Elsevier, 2017-07-27)It is well established that greenhouse conditions prevailed during the Cretaceous Period (~ 145–66 Ma). Determining the exact nature of the greenhouse-gas forcing, climatic warming and climate sensitivity remains, however, ... -
Oligocene Deep-Water Agglutinated Foraminifera from the Congo Fan, Offshore Angola: Palaeoenvironments and Assemblage Distributions
(Grzybowski Foundation, 2008)Agglutinated foraminiferal assemblages from the Oligocene section of an exploration well drilled in the distal part of the Congo Fan are fully documented and interpreted for palaeoenvironment. A total of 65 ditch cutting ... -
Foraminifera from the Eocene variegated shales near Barwinek (Magura unit, Outer Carpathians), the type locality of Noth (1912) revisited
(Polish Geological Society, 2005)A rich deep-water agglutinated foraminifera (DWAF) fauna (approximately 50 taxa) is documented from the lower to middle Eocene Variegated Shales of the Magura Unit, Outer Carpathians. Four localities have been sampled from ... -
Do volcanoes trigger climate change?
(NERC, 2009-12-01)Huge volcanic eruptions may have pushed the climate from global warming to global cooling 16 million years ago. The theory could have big implications for efforts to slow climate change by fertilising plankton in the ocean. ... -
Palaeoclimatic implications of high-resolution clay mineral assemblages preceding and across the onset of the Palaeocene–Eocene Thermal Maximum, North Sea Basin
(Mineralogical Society, 2017-01-04)Understanding the composition of clay-rich sediments and their transportation into proximal marine basins allows us to better decipher hydroclimatic changes before and within the Palaeocene–Eocene Thermal Maximum (PETM). ... -
Modern deep-water agglutinated foraminifera from IODP Expedition 323, Bering Sea: ecological and taxonomic implications
(Geological Society / Micropalaeontology Society, 2017-04-05)Despite the importance of the Bering Sea for subarctic oceanography and climate, relatively little is known of the foraminifera from the extensive Aleutian Basin. We report the occurrence of modern deep-water agglutinated ... -
Element/Ca, C and O isotope ratios in modern brachiopods: Species-specific signals of biomineralization
(Elsevier, 2017-03-31)Fossil brachiopods are of major importance for the reconstruction of palaeoenvironmental conditions, particularly of the Paleozoic. In order to better understand signals of ancient shell materials, modern analogue studies ... -
Early diagenetic evolution of the Chalk in eastern Denmark
(Wiley Open Access, 2016-10-18)The genesis of polygonal faults is an intriguing diagenetic phenomenon. This study discusses their origin in carbonate mudstones together with other associated diagenetic features. In the eastern Danish Basin, at the fringe ... -
Use of a remotely piloted aircraft system for hazard assessment in a rocky mining area (Lucca, Italy)
(European Geosciences Union, 2017-06-14)The use of remote sensing techniques is now common practice in different working environments, including engineering geology. Moreover, in recent years the development of structure from motion (SfM) methods, together with ... -
Characterization of Rock Fracturing for Vertical Boreability
(Elsevier, 2017-06-21)Boreability can be defined as the ability of a bore to penetrate a rock mass. Understanding the factors influencing boreability is critical for enhanced project planning and reduce geotechnical risk in an offshore shaft ... -
The Use of Remote Sensing Techniques for Monitoring and Characterization of Slope Instability
(Elsevier, 2017-06-21)Understanding changes in slope geometry and knowledge of underlying engineering properties of the rock mass are essential for the safe design of man-made slopes and to reduce the significant risks associated with slope ... -
Geology, geochemistry and geochronology of the Songwe Hill carbonatite, Malawi
(Elsevier for Geological Society of Africa, 2017-06-02)Songwe Hill, Malawi, is one of the least studied carbonatites but has now become particularly important as it hosts a relatively large rare earth deposit. The results of new mapping, petrography, geochemistry and geochronology ... -
An investigation into the development of toppling at the edge of fractured rock plateaux using a numerical modelling approach
(Elsevier for International Geosynthetics Society (IGS), 2017-03-24)The mechanisms controlling the onset of minor slope instability at the edges of rocky plateaux exhibiting lateral spreading phenomena are yet to be fully understood. Hypotheses have recently been introduced to explain the ... -
Pliocene-Pleistocene evolution of sea surface and intermediate water temperatures from the southwest Pacific
(Wiley & American Geophysical Union (AGU), 2016-06)Over the last 5 million years, the global climate system has evolved toward a colder mean state, marked by large-amplitude oscillations in continental ice volume. Equatorward expansion of polar waters and strengthening ... -
Mid Pleistocene foraminiferal mass extinction coupled with phytoplankton evolution
(Nature Publishing Group:, 2016-06-17)Understanding the interaction between climate and biotic evolution is crucial for deciphering the sensitivity of life. An enigmatic mass extinction occurred in the deep oceans during the Mid Pleistocene, with a loss of ... -
