Information extraction and integration in mineral exploration.
… of this study. Tools are designed to aid in exploration for common mineral deposits by intelligently and efficiently processing spatial geological data. Gabor filters, comprising Gaussian-attenuated sinusoidal weight vectors, are used for textural discrimination. A highly non-linear logic …

Optimization of UAV-borne Aeromagnetic Surveying in Mineral Exploration
… surveys for improved target characterization in mineral exploration. Specifically, the design and viability of a suspended, semi-rigid magnetometer mounting system integrated on multi-rotor UAVs is investigated. Although a semi-rigid mount offers some technical benefits over other mounting …

Profiling Bacterial Community Dynamics For Wildlife Ecology and Geological Mineral Exploration
… amplicon sequencing is an approach to microbiome exploration that profiles community composition, structure, and dynamics across environmental conditions. In this thesis, 16S rRNA gene amplicon sequencing is used to investigate the bacterial communities of two distinct microbial environments. In …

Gold mineralisation and mineral exploration within the Clogau mine, Dolgellau gold belt, N Wales
… fracture reactivation is believed to accompany mineralisation with gold localization partially controlled by fracture-hosted pathways. Research in this study found gold grades, a measure of the abundance of gold ore, within borehole GMOW_LL001 in 36 places, with the most significant results …

Nanoscale geochemistry of critical elements; applications for mineral exploration and recovery from secondary sources
… nanogeochemistry of critical elements in both mineral exploration and resource recovery contexts. Single particle inductively coupled plasma mass spectrometry (spICP-MS) is employed in Chapter 2 to improve characterization of mineral nanoparticles with respect to their size distributions and …

Recognising cryptic alteration surrounding the Mount Isa Copper Deposits: Implications for controls on fluid flow, and mineral exploration
… cryptic alteration haloes associated with copper mineralisation at Mount Isa, Northwest Queensland, Australia. New insights from hydrothermal alteration were used to constrain aspects of hydrothermal fluid flow and fluid-rock interactions that occurred as part of the mineralising system …

Pining for an anomaly: Biogeochemical mapping of the Cobar Basin for mineral exploration at regional to local scales.
In geochemical mapping for mineral exploration or environmental purposes, the choice of sampling media is influenced by the source, form, mobility and spatial distribution of the elements being mapped. The potential advantages of plant organs over regolith materials include the capacity of plants …

The landscape evolution, geochemistry and biogeochemistry of Kangaroo Island
… for the use of regolith and vegetation in mineral exploration on Kangaroo Island, South Australia. Regolith field observations and the production of a regolith–landform map have improved constraints on the ferricrete plateau formation and also on the landscape history of the Island. The …

Patterns of distal alteration zonation around Antamina Cu-Zn skarn and Uchucchacua Ag-base metal vein deposits, Peru : mineralogical, chemical and isotopic evidence for fluid composition, and infiltration, and implications for mineral exploration
… The main alteration tracers employed included mineralogy, major and trace element geochemistry, oxygen and carbon isotopes, and the fluorescent signature of calcite veins associated with the fluids conduits. Two areas were selected for this study: the large Cu-Zn Antamina skarn and the Ag-base …

Mineral ecology and network analysis of chromium, platinum, gold and palladium
Data collected on the location of mineral species and related minerals from the field have many great uses from mineral exploration to mineral analysis. Such data is useful for further exploration and discovery of other minerals as well as exploring relationships that were not as obvious even to a …

Integrated quantitative interpretation of multiple geophysical data for geology differentiation
The future of mineral exploration depends on innovative methods of data integration and interpretation because new discoveries are becoming scarcer over the years. As brownfield exploration areas reach maturity and greenfield exploration faces increasingly deeper targets and targets hidden under …

Characterization of Residual Mineral Content of Bauxite Stockpiles in Saline County, Arkansas: An XRD Analysis Approach
… in bauxite stockpiles has focused on critical mineral potential. Previous X-ray Fluorescence studies have identified critical elements in significant concentrations, including uranium (U), thorium (Th), gallium (Ga), molybdenum (Mo), and lanthanides (Ln). This study examines five stockpiles …

Applied mineral economics: an analysis on depletion, taxation and exploration
… focuses on the empirical analysis of mineral economics and policy. The economic analysis and discussion around minerals mostly rely on theoretical models and normative principles. Empirical evidence is not as abundant as theoretical models, creating a gap in the discipline. This study …
