来自五个墨西哥考古遗址的陶器岩石学薄片表明，高原和低地主要中心之间的器皿交换是对等的，或双向的。这些分析与最近的说法相矛盾，即墨西哥湾沿岸是雕刻有肖像图案的陶器的唯一来源。这些说法是基于中子活化的，中子活化依赖于化学元素，而不是实际的矿物，在从大型数据集中识别非本地陶器的能力方面存在重大限制。岩相学表明，这些有问题的陶瓷(因此它们的雕刻图案)具有多个来源，并被广泛交易。
Petrographic thin sections of pottery from five Formative Mexican archaeological sites show that exchanges of vessels between highland and lowland chiefly centers were reciprocal, or two-way. These analyses contradict recent claims that the Gulf Coast was the sole source of pottery carved with iconographic motifs. Those claims were based on neutron activation, which, by relying on chemical elements rather than actual minerals, has important limitations in its ability to identify nonlocal pottery from within large data sets. Petrography shows that the ceramics in question (and hence their carved motifs) have multiple origins and were widely traded.
