Shale lignite and cannel coal ring
The crannog on Llangorse Lake near Brecon in mid Wales was discovered in 1867 and first excavated in 1869 by two local antiquaries, Edgar and Henry Dumbleton, who published their findings over the next four years. In 1988 dendrochronological dates from submerged palisade planks established its construction in the ninth...Redknap, Mark ; Davis, Mary

A jadeitite axehead in the midst of the famous Neolithic flint mines of Spiennes?
More than a century ago, Alfred Lemonnier, Director of phosphatic chalk quarries in the Mons region, donated a jadeitite axehead from Spiennes to the State among a small collection of 'knapped flint'. Originally, this artefact was 12 to 15 cm long. Several scientists tested various ways – destructive or non-destructive...Errera, Michel

Disc-rings made from Alpine rocks, in the social imagination of Neolithic communities
In France, disc-rings of Alpine jades and of serpentinite circulated over very long distances, as far as the Channel Islands and the coast of Brittany. The authors present a typochronological study for each rock type, along with distribution maps and a general social interpretation. Two origins are identified, of which...Pétrequin, P ; Cassen, S ; Errera, M ; Pailler, Yves ; Pétrequin, A-M …

Fifty shades of green: the irresistible attraction, use and significance of jadeitite and other green Alpine rock types in Neolithic Europe
This chapter summarizes the results of two major international projects JADE and JADE 2. These examined the exploitation, circulation, use and significance of artefacts made from jadeite and other green rocks from the Western Alps in Neolithic Europe. The most-widely travelled of all the prehistoric materials, these Alpine jades seem...Sheridan, J A ; Pétrequin, Pierre ; Pétrequin, A-M ; Cassen, S ; Errera, M …

Rings and axeheads of Alpine jades: imports to and exports from the Gulf of Morbihan during the 5th millennium and the beginning of the 4th millennium
During the 5th millennium BC, the gulf of Morbihan played a major role in the circulation of socially-valued goods, especially those made from Alpine jades (jadeitite, omphacitite, eclogite, some serpentinites and, more rarely, nephrite), in the form of disc-rings and polished axeheads. This contribution begins with a review of the...Pétrequin, P ; Pétrequin, A-M ; Cinquetti, Mauro ; Errera, M ; Valcarce, Ramón Fábregas …

Insects
The Lias (or Lower Jurassic) marine sediments seen in the cliffs and scars of the Yorkshire coast form the thickest exposed sequence of this age in England at 450m. These rocks are richly fossiliferous and have been studied since the early 19th century. The sedimentary sequence is important for providing...Kelly, Richard S ; Ross, Andrew ; Nicholson, David B

The creative reinterpretation of axeheads: the use of jadeitite and other Alpine rocks
Axeheads made of jadeitite and of other Alpine rocks (notably omphacitites and fine-grained eclogites) provide a classic example of an artefact type that acquired a symbolic meaning over and above its original functional meaning as a tool for felling trees and working wood. Axes were a necessary tool for farming...Sheridan, J A

Tangled up in blue: the role of riebeckite felsite in Neolithic Shetland
The social processes involved in acquiring flint and stone in the Neolithic began to be considered over thirty years ago, promoting a more dynamic view of past extraction processes. Whether by quarrying, mining or surface retrieval, the geographic source locations of raw materials and their resultant archaeological sites have been...Cooney, Gabriel ; Megarry, William ; Markham, Mik ; Gilhooly, Bernard ; O’Neill, Brendan …

Creating a research framework and strategy for early gold in Britain's auriferous regions
This presentation outlines a current AHRC-funded initiative that has created an international network of those involved in the study of gold, to create a Research Framework and Strategy relating to gold use in Britain's auriferous regions, 2450-800 BC. This deals with issues of locating and characterising the source areas; of...Sheridan, J A
