Absolute dating of fault movements

Journal of the Geological Society, 1992
The papers in this thematic set arise from a meeting jointly organized by the Tectonic Studies Group and the Stratigraphy Committee of the Geological Society and held at Burlington House on 28 November 1990. About 80 people heard oral presentations of 15 papers of which seven are published in this thematic set.

Relative and ‘absolute’ dating of land surfaces

Earth-Science Reviews, 2002
Abstract The dating of land surfaces has long posed problems for geomorphologists. Relative methods (stratigraphic, geomorphic, topographic) are sound and convincing. Exhumed forms may complicate identification and relationships, for both epigene and etch forms have been buried, and exhumed, but in tectonically undisturbed areas, the higher surfaces ...

Introduction to Relative Dating and Absolute Dating video

This short video introduces the two main ways scientists determine the age of a rock or mineral: relative dating and absolute dating. The first half of the video explores relative dating with a short demonstration to highlight key stratigraphic principles and how they are used.

Absolute dating from Mesopotamian records

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1970
In the early 1850s, the pioneering stage of the decipherment of Mesopotamian cuneiform writing, the hallmark of the urban culture of ancient Iraq, was completed. Since then, several hundreds of thousands of clay tablets with this writing have been excavated and are now deposited in various museums of Europe, North America, and the Near East; of these ...

Absolute Dating of the Gihon Spring Fortifications, Jerusalem

Radiocarbon, 2017
AbstractOne of the most impressive structures in Jerusalem’s ancient landscape is the tower that was built to surround and protect the Gihon Spring, Jerusalem’s perennial water source. The structure, first discovered by Reich and Shukron (2004), encompasses the cave in which the spring sprouts from, with walls 7 m thick built of large boulders.

Absolute dating from Egyptian records and comparison with carbon-14 dating

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1970
The purpose of this Symposium being to discuss ‘The impact of the natural sciences on archae­ology’, I feel I am laying myself open to the criticism that the subject of my paper is putting the proper order into reverse, for I cannot pretend that 14 C has yet made any actual impact on our reconstruction of Egyptian ...

Neutron activation analysis of absolutely-dated tree rings

Journal of Radioanalytical and Nuclear Chemistry, 2005
Gold concentration was determined for dendrochronologically-dated wood samples using neutron activation analysis (NAA) and correlation sought with known environmental changes, e.g., volcanic activities, during historic periods. Uptake of gold is sensitive to soil pH for many plants.

On Absolute Dating and North Coast History

Memoirs of the Society for American Archaeology, 1948
While I have become less, rather than more, certain of the possibility of correlating traditional dynasty lists with archaeological periods since American Antiquity published my paper on the subject, the possibility is still worth exploring in an area where we have so few absolute dates to go on.

Dating Historical Buildings: An Update on the Possibilities of Absolute Dating Methods

International Journal of Architectural Heritage, 2015
ABSTRACTThe reconstruction of the history of a building represents a difficult task, as written information is not usually available or incomplete. Some building materials (e.g., bricks, wood) have been classically used for absolute dating while on others has been considered unreliable (e.g., stone).
