Accurate basement delineation is crucial for mineral deposits where formation is associated with a paleo-basement topography, such as in detrital iron ore deposits. In such environments seismic surveys provide useful data to assist the mapping of the basement interface. A key stage of the process is identification of the first arrival of elastic wa...
Seismic data processing and analysis focuses on identifying the arrival of seismic waves or ‘first-breaks’. The identification of the arrival of first breaks is complicated by the variance of recording quality typically found across the dataset. In an exploration setting, models need to be developed and refined multiple times. Picking these first b...
The principle aim of the research was to overcome the challenges faced by modern geophysical data analysts, particularly those working with large multivariate datasets using Self Organising Maps (SOM). SOM is an unsupervised learning technique for multivariate data, which works by taking multiple geophysical datasets for an area of interest, and in...
Shear zones are a geological feature of interest due to their unique electrochemical and structural properties. However, consensus on the causation of their conductivity anomalies at large is not unified. There are many factors to consider when understanding the electrical features of a given shear zone. Composition, including minerals and grain bo...
