Research Interests

Dr. Caprarelli's area of research is in the study of volcanic and tectonic activity of Earth and Mars. She uses geochemical and geophysical data to draw interpretations regarding the specific geodynamic processes responsible for basaltic volcanism on terrestrial planets. She has published (as first author) in the peer-reviewed international journals:
Terra Nova
Journal of Volcanology and Geothermal Research
Mineralogy and Petrology
Australian Journal of Earth Sciences

At UTS Dr. Caprarelli has taught geochemistry, petrology, tectonics. Her current teaching duties are as subject coordinator for Geological Processes (subject code: 91149) and GIS and Remote Sensing (91120), as well as lecturing in Astrobiology in the subject The Biosphere (91107).

She has been (and is) principal supervisor or co-supervisor of Honours and PhD projects in geology, planetary science (Mars), and GIS and remote sensing applied to the study of environmental problems.

A head-count of Australia-based scientists doing research in planetary science was performed in the context of the drafting of the Decadal Plan for Space Sciences [1]. This paper builds on those findings. A search of papers published by Australia-based scientists in the period 2005-2008 was performed. The search returned 91 papers published in international journals by scientists distributed in 7 groups, of which 6 are identified by the affiliations of the researchers, and one, termed Others, is composed of individuals working independently. Correspondence analysis performed on the data returned distinctive associations of the ANU, UNSW and Others groups with the subdisciplines of cosmochemistry, astrobiology and mission data analysis, respectively. These associations are interpreted as indicating clusters of activity that are, or have the potential to grow into, areas of high productivity. A minimalist model to support and organise activity in the potential cluster represented by the Others is presented here.

Planetary science studies the origin of the solar system and whether life exists on other planets. It has the potential to change the way we vie the world and our selves. Planetary science offers a cost effective means for Australia to participate in a pretigious international arena. Space engages the public's imagination and can inspire young people in tehir choice of careers. Students gain a strong foundation in mathematics, fundamental sciences and advanced technology, thereby fostering creativity and promoting a culture of innovation. Despite the absence of a national space program, Australian planetary scientists have strong international reputations in cosmochemistry, planetary geology and planetary geophysics.

In this paper we present part of an ongoing study to telemetry data of Phaethontis, aregion in the western hemisphere of Mars' Southern Highlands. in particular, we focus on an approximately 57,000 km2 area in Gorgonum Chaos. We selected THEMIS visual, MOC narrow angle and MOLA data abvailable from the Arizona State University and Malin Space Sceince Systems web-sites. We carried out multi-level processing of THEMIS and MOC data using the ISIS software and prcessed MOLA gridded data by the GMT software. After processing we input the images into ArcGIS software, We observed, identified and described, both 2- and 3-dimentionally, impact craters, chaotic and polygonal terrains, grabens and gullies. These landforms suggest a complex geological history involving sedimentary and tectonic processes such as meteoritic impact, the presence of underground water and ice, desiccation or freezing of wet sediemnts at least two episodes of extension, and recent aeolian activity.

The High Resolution Stereo Camera (HRSC) on board Mars Express has been transmitting high quality imagery and altimetry data since reaching martian orbit. Observations from orbits h0962 and g0951 showed tectonic features in wto selected areas of north Tyrrhena Terra, in a sub-equitorial region of the southern hemisphere characterised by flat surfaces that could be interpreted as covered by either sedimentary or volcanic deposits. Morphometric analysis of a narrow N-S trending valley, about 80 km long, in the southernmost of the selected areas indicates that this valley formed by crstal extension. In the northernmost area, observation of NW-SE trending ridges characterised by steep SW facing lobate scarps and gentler NE sloping back carps is consistent with prior oberservations of NW-SE trending and NE dipping structures. The HRSC-aided identification of subtle structural features is important for geological reconstruction of Mars.

BACKGROUND: Enteric protozoa are associated with diarrhoeal illnesses in humans; however there are no recent studies on their epidemiology and geographical distribution in Australia. This study describes the epidemiology of enteric protozoa in the state of New South Wales and incorporates spatial analysis to describe their distribution. DESIGN AND METHODS: Laboratory and clinical records from four public hospitals in Sydney for 910 patients, who tested positive for enteric protozoa over the period January 2007 - December 2010, were identified, examined and analysed. We selected 580 cases which had residence post code data available, enabling us to examine the geographic distribution of patients, and reviewed the clinical data of 252 patients to examine possible links between protozoa, demographic and clinical features. RESULTS: Frequently detected protozoa were Blastocystis spp. (57%), Giardia intestinalis (27%) and Dientamoeba fragilis (12%). The age distribution showed that the prevalence of protozoa decreased with age up to 24 years but increasing with age from 25 years onwards. The geographic provenance of the patients indicates that the majority of cases of Blastocystis (53.1%) are clustered in and around the Sydney City Business District, while pockets of giardiasis were identified in regional/rural areas. The distribution of cases suggests higher risk of protozoan infection may exist for some communities. CONCLUSIONS: These findings provide useful information for policy makers to design and tailor interventions to target high risk communities. Follow-up investigation into the risk factors for giardiasis in regional/rural areas is needed. Significance for public healthThis research is significant since it provides the most recent epidemiological update on the common enteric protozoa affecting Australians. It reveals that enteric protozoa cause considerable disease burden in high risk city dwellers, and provides the evidence base for development of targeted ...

The Point macquarie-Tacking Point coastline provides excellent exposures of the accretionary subduction complex and youger magmatic arc rocks that make up much of the New England Fold Belt (also known as the New Enagland Orogen) in north-eastern New South Wales. None geological units, including six formally defined here (Port macquarie Serpentineite, Rocky Beach Metamorphic Melange, Tacking Point Gabbro,Town beach Diorite, Nobbys Beach Lamprophyre and Sea Acres Dolerite) have been identified along this coastline tract. The kaikeree Metadolerite has been redefined. The oldest rocks are prograde lawsoniate eclogite and retrograde blueschist blocks embedded in the chlorite-actinolite schist matrix of the Rocky Beach Metamorphic Melange that occurs as a slab within te Port Macquarie Serpentine. The Port Macquartie Serpentine is a product of alteration of cumulate ultramafic rocks of a c.530 Ma forearc ophiolote. The Watonga Formation is a mostly broen formation that consists of Middle-Late Ordovician pelagic rocks, the mafic oceanic substrate on which these were deposited; younger basalt and olistostromes of porbable ocean island origin; and stuff, sultstone and sandstone infered to be trench fill accreted in te Late Ordovician-Carbvoniferous interval.
