Marine or estuarine radiocarbon reservoir corrections for mollusks? A case study from a medieval site in the south of England

Mollusk shells are frequently radiocarbon dated and provide reliable calibrated age ranges when the regional marine reservoir correction is well-established. For mollusks from an estuarine environment the reservoir correction may be significantly different than the regional marine reservoir correction due to the input of bedrock or soil derived carbonates. Some mollusk species such as oysters are tolerant of a significant range of salinities which makes it difficult to determine which reservoir correction is appropriate. A case study is presented of an anomalous radiocarbon age for an oyster shell paint dish found in the fabric of the ruined nave walls of St Mary's Church, Shoreham-by-Sea, West Sussex, England. Stable isotopes (delta O-18 and delta C-13) were used to establish the type of environment in which the oyster had lived. Paired marine and terrestrial samples from a nearby medieval site were radiocarbon dated to provide an appropriate reservoir correction.

The Deconstructed Church: Understanding Emerging Christianity

The Emerging Church Movement (ECM) is a reform movement within Western Christianity that reacts against its roots in conservative evangelicalism by “de-constructing” contemporary expressions of Christianity. Emerging Christians see themselves as overturning out-dated interpretations of the bible, transforming hierarchical religious institutions, and re-orientating Christianity to step outside the walls of church buildings toward working among and serving others in the “real world.”

Drawing on ethnographic observations from emerging congregations, pub churches, neo-monastic communities, conferences, online networks, in-depth interviews, and congregational surveys in the US, UK, and Ireland, this book provides a comprehensive social scientific analysis of the development and significance of the ECM. Emerging Christians are shaping a distinct religious orientation that encourages individualism, deep relationships with others, new ideas around the nature of truth, doubt, and God, and innovations in preaching, worship, Eucharist, and leadership.
