Souza and Perez Filho (2019) inferred two transgressive events in the Late Holocene record of lower Ribeira de Iguape River and Ilha Comprida barrier, Southeastern Brazil, based on luminescence ages and paleoenvironmental interpretation of four columnar sections. In the present paper, we discuss inconsistencies on the methods applied and sample design adopted by those authors, which lead to an incorrect model of coastline evolution for the region over the time period covered by the dates obtained. The dataset presented by Souza and Perez Filho (2019) allows the reinterpretation of the deposits studied as regressive and fits into previous models of regional coastal evolution.

Souza 和 Perez Filho（2019 年）根据四个柱状剖面的发光年龄和古环境解释，推断了巴西东南部 Ribeira de Iguape 河下游和 Ilha Comprida 屏障的晚全新世记录中的两次海侵事件。在本文中，我们讨论了这些作者所采用的方法和样本设计的不一致，这导致该地区在所获得的日期所涵盖的时间段内的海岸线演变模型不正确。Souza 和 Perez Filho（2019 年）提出的数据集允许将研究的沉积物重新解释为退行性沉积，并适合先前的区域沿海演化模型。
