Carbonation of borehole seals: comparing evidence from short-term laboratory experiments and long-term natural analogues [PDF]

open access: yes, 2012
It is crucial that the engineered seals of boreholes in the vicinity of a deep storage facility remain effective for considerable timescales if the long-term geological containment of stored CO2 is to be effective.

Eels as Hosts for Parasitic Mussels: The Importance of Endangered Species Co‐Management

open access: yesAnimal Conservation, EarlyView.
The ability of Unionid mussels to utilize eels as hosts has not been investigated thoroughly, particularly in Europe; therefore, we investigated the transformation success of Europe's seven most common unionid species after infestation on the European eel (Anguilla anguilla).

An investigation into the controls of granite plutonism in the Sierra da Freita region, Northern Portugal [PDF]

open access: yes, 2012
The Serra da Freita region of north central Portugal was chosen for study as it displays the complex relationships between regional structure, plutonism, regional and contact metamorphism typical of this part of Iberia.

Macau as Method: Recombinant Urbanism in Post‐Socialist China

open access: yesAsia Pacific Viewpoint, EarlyView.
ABSTRACT In ‘Asia as Method’, Chen Kuan‐Hsing argues for the value of an indigenous inter‐Asian approach to analysing the effects of European imperialism on the countries and citizens of Asia. This article mobilises both Chen's inter‐Asian referencing strategy and the city‐state of Macau to explore Macau's role in China's engagements with global ...

Geochronological study of post-metamorphic granite from Kasumi Rock, Lutzow-Holm Complex, East Antarctica [PDF]

open access: yes, 2004
Kasumi Rock is situated in the amphibolite-facies metamorphic zone in the Lutzow-Holm Complex, East Antarctica. In this area, granitic rocks occur as steeply dipping linear dykes with sharp intrusive contacts, and cross-cut the foliation of layered ...

Tracking Bronze Age ‘itinerant smiths’ in western Poland: insights from Nd and Sr isotope data

open access: yesArchaeometry, EarlyView.
Abstract The neodymium (Nd) isotope composition of stone casting moulds found in graves of Bronze Age ‘itinerant smiths’ in western Poland was analysed to determine the provenance of their raw materials. For the first time in archaeological research, the Nd model age (TDM)—a highly useful parameter in studying the provenance of geological materials—has

Accessory minerals: a provenancing tool for steatite quarries

open access: yesArchaeometry, EarlyView.
Abstract Steatite has been a widely traded material across a range of archaeological contexts. Yet, challenges inherent to determining its provenance limits our understanding of the networks and mechanisms of its exchange. We present a robust new accessory mineral provenancing “fingerprint” method based their specific growth history.
