Zusammenfassung

A discussion of the various scientific methods used to help in the dating of archaeological finds. It covers such aspects as radiocarbon dating, magnetic dating, amino acid racemization, obsidian hydration and other chemical methods plus luminescence dating and electron spin resonance.

Science-Based Dating in Archaeology Zusammenfassung

Science-Based Dating in Archaeology M.J. Aitken

Archaeologists and archaeology students have long since needed an authoritative account of the techniques now available to them, designed to be understood by non-scientists. This book fills the gap and it offers a two-tier approach to the subject. The main text is a coherent introduction to the whole field of science-based dating, written in plain langauge for non-scientists. Additional end-notes, however, offer a a more technical understanding, and cater for those who have a scientific and mathematical background.

Science-Based Dating in Archaeology Bewertungen

'Martin Aitken xxx; provides just the kind of lucid, well-balanced view of these new dating methods which archaeologists have long been waiting for.'

Inhaltsverzeichnis

Part 1 Generalities: the impact of scientific techniques; absolute dating and derivative dating; the event being dated; reasons for dating; which technique?; dating terminology. Part 2 Climatic clocks and frameworks: climate-based frameworks; the oxygen-isotope timescale - the Milankovitch astronomical theory of climate; the pollen record (palynology) - late-glacial and postglacial dating in NW Europe, pollen assemblage zones (PAZ), correlation with the oxygen-isotope timescale - La Grand Pile, Les Echets; varve chronology - the Scandianavian varbe chronology, the Lake of Clouds, Minnesota; dendrochronology (tree-ring dating - the European oak and bristlecone pine chronology. Part 3 Radiocarbon dating: the essential basis; the carbon exchange reservoir; concentration ration variations - past millennia; recent, man-made disturbances; other cosmogenic isotopes - calcium -41; the two approaches - beta activity and atom counting - accelerator mass spectrometry (AMS); effect of contamination; samples and sampling - wood, bone, shell, sediments and soild, peat, mortar, stalagmites etc; step towards a calendar date; beyond calibration. Part 5 Potassium-argon, uranium-series, fission tracts. Part 6 Luminescence dating: thermoluminescence (TL); paleodose and annual dose; on-site procedures; laboratory measurements - Alpha counting, Beta TLD, alkali feldspar - the isochron technique, zircon dating; accuracy and error limits, date citation, age range; authenticity testing; beyond pottery - burnt flint, burnt stones, unburnt materials - calcite, shell, bone and teeth; optical dating - dating of mineral fractions from Viking pottery fragments, dating of the church of Santa maria Foris Portas, Lombardy, Italy. Part 7 Electron spin resonance (ESR): radioactivity and annual dose; applications - stalagmitic calcite, travertine, tooth enamel. Part 8 Amino acid racemization, obsidian hydration, other chemical methods. Part 9 Magnetic dating and magnetostratigraphy: the Earth's magnetic field; recording mechanisms - thermoremanent magnetism (TRM)k viscous remanent magnetism (VRM), sediments (DRM, PDRM CRM); sampling and measurement; the magnetic polarity timescale (reversal stratigraphy); archaeomagnetism - the Fisher index.
