The radiocarbon dating of Thien Long Uyen and Cuc Bo archaeological sites

Abstract

One of the key factors of archeological research is to determine the age of a archaeological site and the excavated features and artifacts. Among various methods to identify ages, the one that deternines age based on radio carbon content (14C) in archeological samples tends to be used more widely and completely in terms of equipment and interpretation. Thien Long Uyen was excavated in a large scale and used modern methods and techniques. Results show that it is an important historical site, but complicated as the number of organic relics were well preserved. This is suitable for taking a collection of samples to determine accurate age. In this paper, we presents our findings after analysis of age from 15 samples. These samples were sent to the
National University of Australia for analysis with strict principles, i.e., collecting, storing, sending and treating samples so that we could obtain reliable results of the existence time of the site. In order to make comparisions and confirm the potentials and accuracy of this method, the paper also mentions four samples of short-life plants in Cuc Bo, a little younger place than Thien Long Uyen.
