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.

My three primary research themes include:

1) geological characterisation & dating of early anthropoid primate and hominin records from karst systems of South Africa (e.g. Rising Star Cave) and rift deposits of the East African Rift System.

2) palaeontological exploration, stratigraphy and dating of Jurassic & Cretaceous strata throughout Gondwana (esp., Australia; Africa; Antarctica).

3) stratigraphy, palaeontology & high-precision geochronology of the Western Interior Basin, North America.

****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
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
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.

Life and death of Australopithicus sediba: how a potential ancestor ended up dead in a cave in world heritage site in South Africa

Indicative Funding: $256,000 over 2 years
Summary: In August 2008 the remarkable Malapa fossil site was discovered with remains of the first and only fossils of Australopithecus sediba - a potential direct human ancestor. The fossils are in an exceptional state of preservation, and excavations will start in late 2013, creating a unique opportunity to develop a detailed understanding of the chemical, physical and biological factors that led to burial and fossilisation. This research will focus on the complex interplay between termites, sediment chemistry, landscape conditions and palaeo-climate as contributing factors to fossil preservation. Results will document the environment in which sediba lived and died, and assist future exploration for hominid fossils.

Combined U-Pb zircon geochronology & Lu-Hf analysis of Jurassic-Cretaceous volcanics and sandstones from the Lord Howe Rise and Queensland Plateau, Australia

Indicative Funding: $10,000
Summary: We prosed to combine zircon geochronology on putative Cretaceous volcanics reported in the DSDP Leg 21-207 and combine this with more ambitious dual Lu-Hf isotope and U-Pb isotope analysis on detrital zircons collected from a suite of Cretaceous and Paleogene sedimentary rock samples in cores from DSDP Leg 21-206, 207, 208 and 209. This approach is designed to identify the distribution of ages and geochemical signatures associated with earlies Cretaceous-Jurassic age detrital zircons (and volcanics) in order to better understand the timing of Cretaceous-Jurassic volcanism, the possible provenance of Cretaceous-Jurassic volcanic sources and to glean a better understanding of the nature of the magmatism during the Jurassic and Early Cretaceous along eastern Australia.
