摘要放射性碳（14 C）校准曲线中的反转和平台导致类似的14 C年龄适用于广泛的日历日期，造成不精确，模糊和考古定年的挑战。即使使用贝叶斯时序建模，当没有已知的顺序时，这样的时期仍然是一个问题，例如，地层层序存在，特别是如果现场持续时间相对较短。使用反转/高原AD 1480-1630和北美东北部的考古学作为我们的例子，我们认为可能的策略，以提高时间分辨率在这种反转/高原时期的地层序列的情况下，包括使用木材木炭TPQs，即使是很短的摆动匹配，和网站的阶段持续时间的限制的基础上，民族历史和考古证据。
ABSTRACT 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.
