About

My primary research focuses on reconstructing the geologic histories of important vertebrate fossil-bearing continental deposits. My research involves sedimentary facies and provenance analysis (heavy mineral geochronology), coupled with taphonomy, ichnology and geochronology. A key aspect of my research is to provide geologic context to the vertebrate and hominin faunas preserved within these basins and karst settings. This holistic approach to sedimentology is critical to testing a variety of hypotheses related to past environments and climates, uplift and drainage histories, palaeobiogeography, and extinction and evolution of vertebrate and plant communities.

I also maintain close links with industry on a varitety of projects ranging from diamond exploration to petroleum geology to helium exploration.

My primary research themes include:

1) geological characterisation & dating of vertebrate records, including hominins, from rift deposits of the East African Rift System & karst systems of South Africa (e.g. Rising Star Cave)

2) Geological and palaeontological investigation of Jurassic & Cretaceous basins throughout Gondwana (esp., Australia; Africa; Antarctica).

3) Stratigraphy, palaeontology & high-precision geochronology of Upper Cretaceous dinosaur-bearing strata of Western Interior Basin, North America (esp., Kaiparowits Basin, Utah).

4) Industry-linked research collaboration in economic geology and exploration.

****I am always seeking students interested in conducting PhD research that integrate tectonic, sedimentologic (detrital geochronology) and palaeontologic data for reconstructing Mesozoic-Cenozoic sedimentary basins in Australia, China, North America, and Africa. James Cook University offers competitive PhD scholarships to well-qualified applicants. Please email me for details (eric.roberts@jcu.edu.au).****

Jurassic Arc? Reconstructing the Lost World of Eastern Australia

Indicative Funding: $284,390 over 3 years
Summary: This project aims to resolve a long-standing enigma about the geological formation of the Great Artesian Basin ? Australia?s most important onshore reservoir for groundwater and hydrocarbon resources. Specifically, the project will integrate sedimentological and geochemical studies to investigate the geodynamic configuration of Eastern Australia during the Jurassic Period of basin formation. The intended outcomes are an improved understanding of the evolution of the Australian continent and better knowledge of the formation of intercontinental sedimentary basins, which includes better assessment of their potential to contain hydrocarbon resources.

Understanding the Stratigraphy, age, and provenance of the diamondiferous Calonda Formation in North-Eastern Angola: Implications for regional magmatism and paleo fluvial drainage evolution

Indicative Funding: $68,000 over 2 years
Summary: The pilot research, based on four Calonda Formation Core Samples, has identified a suite of unexpected Permian-Late Cretaceous magmatic detrital zircon populations, which have the potential to improve our understanding of the age and provenance of the Calonda Formation, as well as the tectonic history of this region. The pilot research identified a suite of Cretaceous detrital zircons that form three discrete age clusters, which we hypothesis may have been produced during kimberlite or other alkaline volcanism; perhaps synchronously with deposition of the Calonda Formation or other Cretaceous cover sequences. However, due to the small number of grains discovered in the pilot study and lack of systematic sampling, robust conclusions cannot be drawn at present. However, the results demonstrate that it should be possible to significantly refine the age of these sedimentary sequences, including the Calonda Formation, through detrital zircon geochronology, as well as to study the geochemistry of these grains to better understand the regional tectonics of this area during the Cretaceous, possibly including better dating of the timing of kimberlite volcanism.

Dating hominin fossils in the East African Rift, Malawi

Indicative Funding: $25,787 over 1 year
Summary: This project will use detrital zircon geochronology to date the Paranthropus boisei and Homo rudolfenisis hominin fossils from the northern Malawi Rift. These fossils are remarkable, as they represent a co-occurrence of these two species in southwestern Africa, the meeting point for endemic faunas of both southern and eastern Africa. The location of the fossils in the volcanic East African Rift System is a perfect depositional setting in which to apply detrital zircon geochronology to precisely date P. boisei and H. rudolfensis, to test hypotheses about faunal exchange between the two 'cradles' of humankind, in south and east Africa.
