Livingston Data, AZ V:5:121 (ASM): Strata

The strata represent major natural or cultural depositional events such as erosional fill, roof fall, floor contexts, and sterile substrate. Strata are depicted as horizontal rows of interconnected boxes on a Harris Matrix. Within a feature, each stratum is designated by the feature number (e.g., 10, 11, 12, etc.) and a letter that designates a particular stratum (e.g., A, B, C). The letters are assigned in descending order. Mixed levels and artifacts collected out of context are designated by a "?". Artifacts from each feature (or mixed context) are tallied according to strata. Please see column metadata for further detail.

地层代表主要的自然或文化沉积事件，涵盖侵蚀充填堆积、顶板垮落堆积、地面堆积层以及无人工遗物的基底。在哈里斯矩阵（Harris Matrix）中，地层以相互连接的水平方框行进行可视化展示。在单个遗迹单位内，每一层地层由遗迹编号（如10、11、12等）与标识该特定地层的字母（如A、B、C）共同标注。字母按照降序规则进行分配。混杂堆积层位与脱离原生层位采集的出土遗物，均以“？”进行标记。各遗迹单位（或混杂堆积）的出土遗物将按地层进行统计汇总。更多详细信息请参阅列元数据。
