与遗弃有关的抽象沉积在整个玛雅低地被广泛记录下来，与发生在经典玛雅中心礼仪区的最后活动有关。各种模型被用来解释这些背景形成背后的活动，包括那些与迅速放弃(例如战争)有关的活动，以及其他侧重于更持久的事件(终止仪式和/或朝圣)的活动。在这里，我们评估了三种不同节奏的时间情景的贝叶斯模型，以解释伯利兹贝克波特周围废弃矿床的形成。利用来自这些沉积物的地层信息，在人工制品上发现的象形文字年代，以及来自B组烘焙锅三个沉积物中不同地层的人类骨骼遗骸和动物群遗骸的直接年代，我们识别出跨越公元8世纪至9世纪的多个沉积事件。这些结果表明，与制度化统治的崩溃及其劳动命令建造和维护礼仪空间相关的过程在烘焙锅是旷日持久的，证据表明最终的沉积活动可以追溯到9世纪中后期。这段沉积与8世纪早期的沉积(S)在时间上是不同的。总而言之，这些数据提供了烘焙锅经典时期结束的详细情况，在这个时期，遗址的仪式空间在一个多世纪的时间里慢慢地被废弃。
ABSTRACT Deposits linked to abandonment have been widely recorded across the Maya lowlands, associated with the final activities occurring in ceremonial areas of Classic Maya centers. Various models have been applied to explain the activities that lie behind the formation of these contexts, including those linked to rapid abandonment (e.g., warfare) and others focused on more protracted events (termination rituals, and/or pilgrimages). Here, we assess Bayesian models for three chronological scenarios of varying tempo to explain the formation of peri-abandonment deposits at Baking Pot, Belize. Using stratigraphic information from these deposits, hieroglyphic dates recovered on artifacts, and direct dates on human skeletal remains and faunal remains from distinct layers in three deposits in Group B at Baking Pot, we identify multiple depositional events that spanned the eighth to ninth centuries AD. These results suggest that the processes associated with the breakdown of institutionalized rulership and its command of labor to construct and maintain ceremonial spaces were protracted at Baking Pot, with evidence for the final depositional activity dated to the mid-to-late ninth century. This interval of deposition was temporally distinct from the earlier deposition(s) in the eighth century. Together, these data offer a detailed view of the end of the Classic period at Baking Pot, in which the ceremonial spaces of the site slowly fell into disuse over a period of more than a century.
