在对大量的文物进行分析之前，建议对黑曜石来源进行系统的样品收集、化学分析和统计评估。基于Mahalanobis D 2的多变量统计方法能够鲁棒地拒绝错误的源分配，并导致具有非常高的置信度的工件的来源。这些多变量程序还可以帮助识别和评估更快速和更便宜的简化分析方法。测试案例的基础上，黑曜石数据源在中美洲。
A systematic approach to sample collection, chemical analysis, and statistical evaluation of obsidian sources is recommended before significant numbers of artifacts should be analyzed. Multivariate statistical methods based on Mahalanobis D 2 enable robust rejection of erroneous source assignments and lead to sourcing of artifacts with a very high degree of confidence. These multivariate procedures can also assist in identifying and evaluating abbreviated analytical methods that are more rapid and less expensive. Test cases based on obsidian data from sources in Mesoamerica are presented.
