Dr Samuel C Boone is a geoscience research fellow in tectonics and thermochronology. His work aims to better our understanding of Earth's dynamic evolution by constraining the thermal and tectonic history of the crust in relation to the growth and breakup of continents. To do this, he integrates field observations, low-temperature thermochronology, structural geology, geochronology, and geochemistry.

Dr Boone commenced his role at the University of Adelaide as a research fellow in 2022. In collaboration with Associate Professor Stijn Glorie, he aims to investigate the interplay between tectonics, climate, and resources through a megacontinental-scale synthesis of the upper crustal thermal evolution of Gondwana in response to continental breakup over the last 200 million years. He is also a member of the Tectonics and Earth Systems Group (TES) in Adelaide, where he is working with Prof Alan Collins and Dr Morgan Blades to investigate the tectonics of the Neoproterozoic East African Orogen.

Sam splits his time between Adelaide and the University of Melbourne where he is a leader of the Melbourne Thermochronology Research Group, specialising in the development and application of fission track and (U-Th)/He analyses of the common accessory mineral apatite and other uranium-enriched minerals, including zircon, titanite, and monazite. They conduct research across all aspects of the development of laboratory techniques, as well as their application to understanding the low-temperature history of continental crust in response to continental extension, sedimentary basin development, orogenesis and continental amalgamation, landscape evolution, and the long-term stability of cratons.

Sam is also a leading member of the AuScope Geochemistry Network, an Australian consortium of Earth Science Institutes cooperating to develop national geochemistry infrastructure. Their flagship project is the development of AusGeochem, a FAIR data platform enabling researchers to solve geoscience challenges through geospatial interrogation of geochemistry Big Data on a global scale.

Why do continents break apart?  

The breakup of continents along rift systems plays a fundamental role in the theory of plate tectonics, leading to the creation of new oceans and continental margins instrumental in driving the evolution of the Earth’s climate and biosphere. Active rift systems also host important economic resources, such as low-carbon geothermal energy systems. Yet despite the important role of continental breakup in how our planet has evolved and operates, the mechanisms controlling the initiation and localisation of rifting remain enigmatic. Sam's work aims to quantify the natural processes controlling the inception and early evolution of continental rifts by integrating geochemical and field observations of active rift systems, namely in East Africa.  

Continental margins record the signature of ancient periods of rifting, lithospheric plate rupture, ocean basin formation, the growth of topography and mass sediment transportation. The southeast margin of Madagascar (pictured) records the breakup of central Gondwana, when Africa, Madagascar, Antarctica, India and Australia began gradually dispersing approximately 180 million years ago, forming the Indian Ocean in their wake.

The growth of supercontinents  

The distribution of continents, mountain ranges, and oceans associated with the growth of supercontinents is thought to be instrumental in driving the most dynamic periods of evolution for the interior of Earth, the climate, and life. Nevertheless, details of the development of supercontinents often remain poorly constrained. Using a range of geochemistry techniques in combination with structural geology and field observation, Sam aims to restore the amalgamation history and configuration of ancient supercontinents to better understand the most dynamic periods of Earth’s evolution.

Supercontinent assembly occurs via episodic periods of tectonic plate collision, resulting in the growth of the largest mountain belts on Earth. But long after these peaks have eroded away, the signature of ancient collisional events can still be detected by the structural, magmatic and chemical fingerprints they leave behind. Mt Everest and the Nepalese Himalaya (pictured from the summit of Gokyo Ri) record the collision of India with Asia over the last 55 million years. Image credit: S.C. Boone.

Developing tools to constrain the thermal evolution of Earth’s crust  

Dr Boone specialises in the development and application of temperature-sensitive radiometric dating techniques that can be used to constrain the thermal evolution of the crust in relation to mountain building events, continental breakup and landscape evolution. To develop these so-called low-temperature thermochronology methods, he integrates digital microscopy, chemistry, spectrometry, software engineering, and machine learning in laboratory and fieldwork. Below is a preview of the open-access AusGeochem geochemistry data platform which he has worked to develop as part of the AuScope Geochemistry Network.
