This paper reports on the conservation measures taken to protect and display the remains of a pre-Islamic Christian monastic complex on Sir Bani Yas Island, Abu Dhabi, UAE, and the reasoning behind the decisions. The excavated areas of the site are now partly sheltered, and partly reburied. Observations are made on the effectiveness of the shelter building, and the reburial system used between 1996 and 2010, and on the measures currently being used to preserve plaster fl oors and faced standing walls in aggressive environmental conditions. Work has been carried out to fi nd ways to make the site as legible as possible while also conserving it. Methods of site monitoring are also discussed.keywords reburial, wall capping, shelters, lime mortar, sustainable conservation, Gulf tourism fi gure 1 Tourists and guide at the site while archaeological team works.
We analysed corrosion from a copper bowl dating from the Roman period (43–410 AD) found in a farm in Kent, UK. Despite its relatively good condition, the interior and exterior surface of the object had areas of deterioration containing green and brown-coloured corrosion which were sampled for characterization by a multi-analytical protocol. Basic copper chlorides atacamite and paratacamite were identified in the context of mineral phases along with chlorobenzenes in the green corrosion. Chlorobenzenes are common soil contaminants in rural areas from the use of pesticides, many of which were banned more than 50 years ago. Here we show that their presence is associated with accelerated corrosion, and this provides a threat to the preservation of archaeological metal objects in the ground.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
