Reversals and plateaus in the radiocarbon (14C) calibration curve lead to similar 14C ages applying to a wide range of calendar dates, creating imprecision, ambiguity, and challenges for archaeological dating. Even with Bayesian chronological modeling, such periods remain a problem when no known order—e.g., a stratigraphic sequence—exists, and especially if site durations are relatively short. Using the reversal/plateau AD 1480–1630 and the archaeology of northeastern North America as our example, we consider possible strategies to improve chronological resolution across such reversal/plateau periods in the absence of stratigraphic sequences, including uses of wood-charcoal TPQs from even very short wiggle-matches, and site phase duration constraints based on ethnohistoric and archaeological evidence.

解决放射性碳高原非分层短期环境中的时间问题：公元 1480-1630 年示例和北美东北部的可能性和挑战

放射性碳的逆转和高原（14C) 校准曲线导致相似14C 年龄适用于广泛的日历日期，给考古测年带来不精确、模棱两可和挑战。即使使用贝叶斯年代模型，当不存在已知顺序（例如地层序列）时，尤其是在站点持续时间相对较短的情况下，此类时期仍然是一个问题。以公元 1480-1630 年的反转/高原和北美东北部的考古学为例，我们考虑了在没有地层序列的情况下提高这种反转/高原时期的时间分辨率的可能策略，包括使用木炭 TPQs非常短的摆动匹配，以及基于民族历史和考古证据的场地阶段持续时间限制。
