Crenostrea sp. cf. C. cannoni (Marwick, 1928) (Bivalvia: Ostreoidea) and associated fauna from east of Heard Island,Kerguelen Plateau: age and palaeoenvironmental value

Quilty, P.G., Clark, N. & Hibberd, T., 21.01.2015. Crenostrea sp. cf. C. cannoni (Marwick, 1928) (Bivalvia: Ostreacea) and associated fauna from east of Heard Island, Kerguelen Plateau: age and palaeoenvironmental value. Alcheringa 39, xxx–xxx. ISSN 0311-5518

A well-preserved single left valve of a large oyster embedded in coarse volcaniclastic sediment and identified as Crenostrea sp. cf. C. cannoni (Marwick, 1928) was dredged from east of Heard Island, central southern Indian Ocean. It is accompanied by a fragment of the pectinid bivalve Austrochlamys sp. indet. and foraminifera. Austrochlamys sp. indet. and other bivalve fragments were analysed for ⁸⁷Sr/⁸⁶Sr, δ¹⁸O and δ¹³C, the results yielding an age of 17.5 Ma (later early Miocene) and a water temperature of ca 10°C. Foraminifera and sediment characteristics indicate that accumulation occurred in mid-continental shelf depths, at a location where nutrient supply was good.

Going global: the transnationalization of care

This article critically examines the contours of ‘care transnationalization’ as an ongoing social process and a field of enquiry. Care transnationalization scholarship combines structural understandings of global power relations with an emphasis on social interactions between defined actors in ways that keep sight of human agency, material welfare and wider social development. It has, however, tended to privilege particular forms, dynamics and sites of care transnationalization over others. The body of research on care labour migration, which is otherwise the most developed literature on care transnationalization to date, contains a number of biases and omissions in its coverage of border-spanning relations and their mediation across country contexts. At the same time, other significant forms of care transnationalization, such as those involving consumer-based care migration, corporate restructuring and the formation of care policy, have suffered from comparative neglect. Working towards an integrated agenda that addresses these diverse expressions of care transnationalization and how they ‘touch down’ in a range of sectoral, social and country contexts is of prime importance to policy research agendas directed at understanding the wider development impacts of processes of social and economic restructuring.     

New discoveries in the Piramide Naranjada in Cahuachi (Peru) using satellite,Ground Probing Radar and magnetic investigations

The detection of buried earthen structures by using remote sensing techniques is still an open issue and a strategic challenge as crucial as it is complex. It is crucial because earthen archaeological remains are widely present thoughtout the world (in South America, Asia, Africa) and it is complex due to the subtle physical contrast between earthen remains and the surrounding subsoil.     

The provenancing of ochres from the Neolithic Temple Period in Malta

Ochres have played an important role in early human societies, and recent studies have shown that these pigments are important tools in establishing trade routes between countries as particular varieties of the material were sought for use by these ancient groups. This paper explores the provenancing of the ancient ochres used during the Neolithic Temple Period on the Maltese islands. Here ICP-AES was employed to establish geochemical trends and ‘signature’ elements present in ochre that had previously been thought to have been imported from mainland Europe. When coupled with statistical tests, data was used to link the archaeological pigments to a geological source. Results revealed a strong link between the Maltese archaeological pigments and local sources, which had never been studied prior to this project. These indicated that, contrary to popular belief, the Maltese archipelago was the most likely source for Neolithic ochre.
