Archaeological science, also known as archaeometry, consists of the application of scientific techniques to the analysis of archaeological materials, to assist in dating the materials. It is related to methodologies of archaeology. Martinón-Torres and Killick distinguish ‘scientific archaeology’ (as an epistemology) from ‘archaeological science’ (the application of specific techniques to archaeological materials). 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.
