Archaeological science
Archaeological science consists of the application of scientific techniques to the analysis of archaeological materials and sites. It is related to methodologies of archaeology. Martinón-Torres and Killick distinguish 'scientific archaeology' from 'archaeological science'. Martinón-Torres and Killick claim that 'archaeological science' has promoted the development of high-level theory in archaeology. However, Smith rejects both concepts of archaeological science because neither emphasize falsification or a search for causality. Marwick demonstrated that archaeologists' publication habits are more like social scientists than hard sciences such as physics.
In the United Kingdom, the Natural and Environmental Research Council provides funding for archaeometry separate from the funding provided for archaeology.
Types of archaeological science
Archaeological science can be divided into the following areas:- physical and chemical dating methods which provide archaeologists with absolute and relative chronologies
- artifact studies
- environmental approaches which provide information on past landscapes, climates, flora, and fauna; as well as the diet, nutrition, health, and pathology of people
- mathematical methods for data treatment
- remote-sensing and geophysical-survey techniques for buried features
- conservation sciences, involving the study of decay processes and the development of new methods of conservation
Dating techniques
Archaeological science has particular value when it can provide absolute dates for archaeological strata and artifacts. Some of the most important dating techniques include:- radiocarbon dating — especially for dating organic materials
- dendrochronology — for dating trees; also very important for calibrating radiocarbon dates
- thermoluminescence dating — for dating inorganic material
- optically stimulated luminescence — for absolutely dating and relatively profiling buried land-surfaces in vertical and horizontal stratigraphic sections, most often by measuring photons discharged from grains of quartz within sedimentary bodies
- electron spin resonance, as used in dating teeth
- potassium-argon dating — for dating fossilized hominid remains by association with volcanic sediments
Artifact studies
- X-ray fluorescence
- inductively coupled plasma mass spectrometry
- neutron activation analysis
- scanning electron microscopy
- laser-induced breakdown spectroscopy
Provenance analysis has the potential to determine the original source of the materials used, for example, to make a particular artifact. This can show how far the artifact has traveled and can indicate the existence of systems of exchange.
