Archaeology Science Journal- ArcheoSciences
“ArchéoSciences Journal of Archaeometry, published annually by the Group of Multidisciplinary Methods Contributing to Archaeology (GMPCA), contains articles in French or English on any original research and unique processing of the application of scientific techniques (physics, chemistry, mathematics, earth science and the universe, and the natural sciences and life) to the solution of archaeological problems or the development of new methods. Articles may focus on methodologies and limitations on basic scientific research or specialized techniques, provided that their archaeological justification is clearly explained.”
There is a 2 year delay between the first publication of an article and when it goes open access. But that is not bad considering many other journals don’t go open access at all. Oh and it is peer reviewed for all you budding academics who are looking for places to publish.
