摘要
The discovery of the radiocarbon(14C)dating technique in the mid-twentieth century by Willard Libby and colleagues(Libby et al.,1949)revolutionised such fields as archaeology and palaeoclimatology that require robust chronological information to inform their study.Any sample yielding sufficient quantities of carbon could be dated in this manner,with the older age limit of the method(currently circa 50 to 60 thousand years ago)having been pushed back significantly since its inception.
