Developing AI-powered automated digital microscopy techniques for the Earth Sciences

The Melbourne Thermochronology Research Group is seeking a highly motivated MSc candidate to pursue a project in the fields of Computer Science and Earth Science at the University of Melbourne, Australia, to begin in 2023. As part of a cross-disciplinary collaboration between the MTRG, the School of Computer and Information Systems and members of the Melbourne Data Analytics Platform (MDAP), this project aims to utilise machine learning techniques to develop artificial neural networks which are capable of identifying, quantifying and characterising microscopic crystallographic features in minerals. Digital microscopy is an emerging cornerstone technology for the Earth sciences, enabling scientists to quantify the optical, morphological and compositional characteristics of geological materials and constrain their provenance, chemical, pressure and thermal histories. The implementation of machine learning techniques into digital microscopy will enable unprecedented analytical automation, helping to remove user bias and making these powerful techniques more widely available to a wider non-specialist community.

The project will focus on the digital fission track methodology, a microscopy-based geological dating technique involving the identification and measurement of radiation damage zones in crystals resulting from spontaneous fission of 238U atoms. This is a technique pioneered by researchers in the MTRG who have developed the world’s leading technology in this area (Fission Track Studios). Utilising an existing database of more than 30,000 photomicrograph stacks of fission tracks in mineral grains, the MSc candidate will develop, train and test an artificial neural network for the purposes of automatically identifying and quantifying 3D crystallographic features under the supervision of MTRG and MDAP researchers. The applicability of the resulting image analysis algorithms to other digital microscopy techniques will also be explored.

Advancing the new monazite fission track technique - a cutting-edge tool for potential investigations into ancient wildfires, paleoclimate and landscape evolution

This MSc will place the candidate at the forefront of developing the cutting-edge monazite fission track technique (MFT), an ultra-low temperature thermochronometer recently developed in the Melbourne Thermochronology Research Group. Laboratory-based experiments (Jones et al., 2021 - Geochronology) indicate that the MFT technique is sensitive to ambient temperatures of geological timescale, making it a potentially powerful new tool for investigating a wide arrray of Earth processes ranging from dating ancient bushfires, constraining past periods of climate change, and quantifying geomorphological landscape evolution.

Through a combination of laser ablation inductively coupled mass spectrometry (LA-ICP-MS), digital microscopy, borehole studies and field sampling, this project will use analytical- and natural-laboratory experiments to test potential applications of this powerful new thermochronology method.

Can we reduce atmospheric CO2 by carbon mineralisation?CarbMineralisation

Carbon mineralisation is a prospective negative emission technology to reduce atmospheric CO2. The idea is to mobilise cations (Ca, Mg, Fe) from mafic and ultramafic rocks under acidic conditions and to precipitate those ions together with carbon from atmospheric CO2. In this study, the pyroclastic (volcanic) rock scoria will be used as a cation source and elevated CO2 pressure will acidify the solution. Once the cation concentrations are high enough, the CO2 pressure will be reduced and carbonate minerals precipitate. Scoria samples from the Newer Volcanic Province will be characterised and simple flow-through experiments (see figure) carried out at various conditions. Simple geochemical modelling using commercial software will be used to explain the observations.

Mapping and modelling the Cambrian unconformity and Bell Point Fault Zone at Cape LiptrapDigger Island

This project is field-based and will involve mapping the east coast of Cape Liptrap, ~200km SE of Melbourne. Mapping will be digital using a tablet or phone so that the data can be transferred into a work-station using the academic licence of MOVE owned by A/Prof. Sandra McLaren. The fault zone and unconformity along the east coast of Cape Liptrap was mapped by Cayley et al (2002, AJES 49 p. 225-254) suggesting a Proterozoic subduction zone beneath folded Ordovician and Devonian carbonates. New geochemical analyses (Bisits in prep) cast a different light on the underlying ophiolite and new (2022) high resolution drone images allow detailed mapping of the fault and unconformity along the coast in a zone ~2 km long. Using the drone images and Field-Move software  the fault and unconformity will be mapped in detail, tying into the geochemistry project by Eleanor Green and Kevin Hill. The data will be entered into Move software to facilitate section construction and potentially a 3D model. The aims are to determine the nature and extent of the unconformity, its deformation history and relationship to the Bell Point Fault Zone.

Research Project on the A1 Gold Mine

The A1 Gold mine, which is one of Victoria’s premier gold (Au) mines has been producing Au intermittingly since 1861, is located in the mountains to the south of Mansfield, Victoria. Much of the A1’s Au production has come from planar quartz reefs developed in reverse faults in the diorites of the ~80 metre wide A1 dyke, which is a member of the Woods Point Dyke Swarm. Recently, a new style of Au mineralization has been discovered in the A1 mine, this being disseminated Au in a granophyric rock that is composed mainly of albite and quartz-albite granophyric intergrowths together with disseminated pyrite, which hosts the Au. The project on offer involves mapping and core logging to establish the relationship between the “normal” dioritic rocks and the granophyric rocks. Laboratory work on the disseminated Au and the granophric host rock will be done using advanced geochemical techniques such as LA-ICP-MS analysis. The aims to the project are to determine 1) the relationship between the two styles of Au mineralization, 2) the genesis of the disseminated Au (is it a product of metamorphic fluids as all the other bedrock Au deposits in Victoria or is it magmatic?) and 3) the petrogenesis of the granophyric rock.

Budj Bim Indigenous technology

The Budj Bim World Heritage Cultural Landscape is internationally recognised for preserving the world’s oldest aquaculture system, which provided an economic and social base for the Gunditjmara people of South-western Victoria for more than six millennia. What technologies were used by Gunditjmara people to carve canals in the volcanic landscape? Oral tradition suggests that fire was used to assist cracking, but empirical evidence is lacking.

A digital image created of the elevation in the carved canals using green and red shading to emphasize shape and depth.

This project will use archaeomagnetic analysis to provide evidence for ancient fire technology. With permission from the traditional owners, volcanic rock samples will be collected in and out the canals. Stepwise thermal demagnetisation will inform on the heating histories since the 40,000 years old Tyrendarra lava flow, including an evaluation of bushfire effect.

This project is part of a larger project led by Dr Martin Tomko (School of Engineering, The University of Melbourne) that aims to elucidate the engineering processes that enabled the Gunditjmara to site, plan, construct, operate and maintain this aquaculture complex, to show how it may have evolved over time, and how it responded to changing social and environmental circumstances. The student will conduct the magnetism experiments at the Australian Archaeomagnetism Laboratory at La Trobe University (Melbourne) in collaboration with Professor Andy Herries.

Was the spread of plant and animal domestication in the Mediterranean influenced by climate change?

The domestication of plants and animals and the shift from hunter-forager to pastoral-agricultural lifeways in the Neolithic was one of the biggest changes in the history of humankind. In the Mediterranean, this began at different times and occurred in different ways across the region. This project seeks to characterise the potential influence of rapid climate change events in the Neolithic transition. It will involve generating high-resolution palaeoenvironmental records from archaeological sites across the Mediterranean using carbonate geochemistry.

Exploring how prehistoric tropical communities adapted to Late Pleistocene to Holocene environmental change in Vietnam

This project combines archaeological, geological and ecological history of the TrĂ ng An massif World Heritage site, Ninh Binh, Vietnam. We will use geochemical records from land snail shells preserved in several archaeological sites to reconstruct local environmental conditions experienced by the region’s past inhabitants. This project will involve aspects of modern proxy validation as well as palaeoenvironmental reconstruction.

Calibration of new high-resolution sea surface temperature proxies for southeastern Australia using mollusc shell chemistry

Mollusc shells have periodic growth increments which allow the reconstruction of chronologically constrained records of palaeoenvironmental variability at unparalleled high temporal resolution. Studying the growth and chemistry of these periodic growth increments is known as sclerochronology. There are few high-resolution marine palaeoenvironmental proxies available for southeastern Australia. Mollusc shell sclerochronology holds great promise for reconstructing quantitative, sub-seasonally resolved sea surface temperature and salinity records from this region via the analysis of shells from Late Pleistocene to Holocene archaeological sites.

However, before these archives can be used for palaeoenvironmental reconstructions, it is necessary to undertake modern calibration studies to understand how geochemical variations are influenced by local environmental conditions, kinetic and vital effects. This allows the generation of quantitative and reliable proxy records of environmental change. This project will use field and lab-based sclerochronological methods on intertidal mollusc species to calibrate new high-resolution palaeoenvironmental proxies for southeastern Australia.

Using giant clam shells to reconstruct past environments and cyclone activity in the tropical Pacific

Giant clams (Tridacna spp.) are one of the major carbonate components of tropical reef systems. Their shells have annual growth increments. By analyzing the growth and chemistry of these increments it is possible to reconstruct past environmental conditions as well as short term events such as cyclones. This project will employ these techniques on modern and fossil clams to provide a palaeoenvironmental and palaeostorm reconstructions from the Late Holocene using samples from the Great Barrier Reef and Polynesia.

Understanding paleoenvironments and human interactions around a mid-Holocene shell midden in South America’s largest inundation savannah(jointly supervised with Dr Jan-Hendrik May)

Early to mid-Holocene archaeological sites are extremely rare in the Amazon basin. Anthropogenic shell middens provide valuable windows into past human-environmental interactions in the northern Bolivian inundation savannah, and hold clues on the type of existing resources, their seasonal to longer-term variability in the landscape, and their link to the natural and paleoenvironmental dynamics in a tropical riverine environment. This project addresses these questions via developing high-resolution records of paleoenvironmental change and seasonal resource use by applying microscopic, geochemical and sclerochronological techniques to freshwater apple snail shells (Pomacea spp.) from a midden in the Bolivian Amazon.

Earth's history through sedimentary geology

A microscopic image of sedimentary rock showing patterned red, orange and yellow coloured lines.

Sedimentary rocks record almost four billion years of Earth’s environmental evolution and the evolution of life. Research in sedimentary geology can be used to identify the timing of tectonism, past climate and vegetation history, environmental change and the evolution of the oceans and atmosphere. Sediment hosted ore deposits and the diagenesis of sediments are also aspects of this research which can be related to industry projects.

Ashleigh Hood and Malcolm Wallace can supervise or co-supervise a variety of projects related to sedimentary geology in any of these areas depending on what prospective Masters and Honours students are interested in. Any project would likely be a combination of fieldwork, petrography and sedimentary geochemistry (laser/isotopes).

Some examples of active areas of research include:

  • Precambrian sediments of the Flinders Ranges including those related to “Snowball Earth”.
  • Neoproterozoic reefs and the evolution of reefs on the early Earth (Flinders Ranges).
  • The oxygenation of the oceans and atmosphere.
  • Phanerozoic iron stromatolites and link to environmental conditions (Flinders Ranges, Victoria).
  • Unusual microbialites from Victorian lakes (analogue for Mars?).
  • Palaeozoic marine redox and link to animal-plant evolution (Victoria, NSW, Tasmania)
  • Archean carbonates and seawater conditions (Western Australia).
  • Rare earth elements in paleo-oceanography
  • McArthur basin, marine evolution and mineralisation (NT)
