Research Themes

Matthew is a key member of the TMVC Research Hub and the Computational Geophysics and Earth Informatics group, led by Associate Professor Anya Reading, at The University of Tasmania. His research combines elements of both the Resources and Sustainability and Data, Knowledge and Decisions University research themes. Matthew's PhD thesis explored the use of data mining and machine learning techniques to identify and analyse patterns in high-dimensional geological, geophysical and geochemical data. Specific focus was placed on generating useful outputs such as robust measures of uncertainty and the development of methods for interpreting inferred relationships.

Currently, Matthew is researching novel approaches to adding value to digital scans of drillcore data, specifically related to the automated detection, extraction and classification of geological features. In addition, Matthew is applying the skills gained through his PhD to addressing the significant challenge of finding deeply buried ore deposits in the regolith dominated terrains of Australia. Matthew is also applying his unique skills to projects that aim to improve our understanding of large-scale tectonic architectures of the Australian and Antarctic continents.

Collaboration

Matthew is working closely with mining and resource partners through the TMVC Research Hub. He is also currently involved in collaborative research projects with the University of California, Riverside and the NASA Astrobiology Institute that aim to discriminate ore deposit styles and biological activity from pyrite trace element analyses. Matthew works closely with Geoscience Australia on a project that aims to identify subtle mineralisation signatures in continental-scale geochemical and geophysical data, and with the University of Canberra's Institute of Applied Ecology developing objective spatial data analysis methods for agricultural and soil conservation land management systems. He has completed research projects and still maintains close links with Mineral Resources Tasmania.

Geophysical investigation of historic Aberfoyle tailings site, northeast Tasmania (2020)$8,382
Description
The Tasmanian State Government has committed AUD$1 million over 4 years to Mining Sector Innovation Program funding (Tasmanian Government, 2017; TMEC, 2017). The aims of this fund are promoting the use of cutting-edge technologies and implementation of best practice management by the Tasmanian mining industry. This funding provides support and research projects across four key streams: 1. Innovative use of geoscientific data using new technologies;2. Investigating innovative solutions for mine rehabilitation and remediation;3. Developing best practice Acid Mine Drainage management guidelines, and4. Improving the understanding of landslip reactivation and implications for emergency responseThe proposed honours project aligns with both innovation in the use of new technologies and solutions for mine rehabilitation and remediation. The Aberfoyle Mine near Rossarden, northeast Tasmania, produced 11,000 tons of tin and 3,500 tons of wolfram from 1931 to 1982. The processed pyritic-rich tailings are stored in nine tailings dams. Recent site rehabilitation was carried out using earth capping over the tailings dam and implementation of vegetation trials. Rehabilitation aimed to decrease the effects of erosion and windblown dust on the tailings but of limited success. The lack of water retention, effects of metal contamination and drought stress, has caused the failure of revegetation trials. In a previous study conducted by McLaine et al. (2017) and McLaine (2017), the tailings were characterised using a mineralogical and geochemical approach. This study found that the tailings have high potential to generate Acid and Metalliferous Drainage (AMD) and exhibit Cd, Cu and Zn concentrations significantly above the national guidelines. Furthermore, surface soil is contaminated with deleterious elements that become more concentrated with depth. This study recommended detailed geophysical investigations be carried out to investigate the properties of soil capping across the abandoned tailings dams at the Aberfoyle site.

Ore deposits and Tectonics of SE Australia: Freeport-McMoRan (2019)$30,000
Description
This project will test and improve the techniques developed by the ARC-funded Linkage project LP160100483 (Ore deposits and tectonic evolution of the Lachlan Orogen, SE Australia). Both the existing Linkage and this new project aim to identify prospective areas for hydrothermal ore deposits in SE Australia through combining mineral chemistry with large-scale plate tectonic reconstructions. The existing Linkage project has acquired a large amount of geochronological and geochemical data on approximately 1500 samples throughout the Lachlan Orogen and developed a new prospectivity model for SE Australia using G-plates software. This new project will extend the data collection and fund a new phase of modelling that will benefit both the existing Linkage project Partners and Freeport-McMoRan.

Identification and characterisation of geological domains for geometallurgical and geoenvironmental modelling (2018 - 2019)$20,000
Description
Mining operations are increasingly reliant on digital geological data to inform all aspects of ore deposit extraction, refinement and remediation. These data, e.g. drill core hyperspectral imagery, contain information on geological features and processes that are typically interpreted by geologists using drill core logs and geochemical assays. Despite this, converting high resolution hyperspectral imagery and associated mineralogical classifications into geological knowledge that informs mine-scale block models is yet to be fully realised. This PhD project will make use of unprecedented access to multi-scale digital geological data from a variety of porphyry and epithermal ore deposits with the overarching aim of defining and characterising geological features relevant to mining operations. Research activities are expected to include investigation, assessment and implementation of image processing and supervised and unsupervised machine learning methods for defining patterns in multi-scale geological data. The outcomes of this project are expected to facilitate the integration of large volumes of digital data from diverse sources with existing geological knowledge in order to develop the next generation of models for ore deposit exploitation. As this PhD project forms part of the ARC Transforming the Mining Value Chain (TMVC) AMIRA P1202 funded "Far-field and near mine footprints" project, specifically within Module 4 "The transition zone". This project will involve close collaboration with TMVC and AMIRA P2102 project industry and academic partners.

Ore deposits and tectonic evolution of the Lachlan Orogen, SE Australia (2016 - 2019)$793,000
Description
South-east Australia has a complex and fragmented geological history. Over the past 550 million years platetectonic processes have resulted in the formation of metal-rich mineral deposits. This project aims to develop andtest models for evaluating past tectonic processes and configurations, using both new and existing geological,geophysical and isotopic data. The information gained will be used to identify areas of high potential foreconomically valuable ore deposits, thereby enabling more efficient prioritisation of mineral exploration efforts.This will increase the probability of significant ore deposit discoveries leading to national economic benefit.
