The Lagoa Salgada is located in the Paraíba do Sul river delta plain on the coast of Rio de Janeiro state, Brazil, and is one of the few lagoons in the world that have well-developed recent stromatolites. Lagoa Salgada is a hypersaline lagoon formed in a very complex environmental system subjected to terrestrial and oceanic influences under different sea level regimes and climate variations. In addition, sediment and stromatolites are characterized by unusually positive inorganic δ13C VPDB values. For this reason, it has been the target of several geological and paleoenvironmental studies, which, in their great majority, require a geochronological technique in order to determine the changes in the environment over time. When radiocarbon (14C) dating is used, it is necessary to consider some details as the source of 14C in the environment and perform 14C ages calibration accordingly. In the present paper, a bibliographic survey was carried out in order to review the data treatment and improve the environmental evolution discussion based on accurate calibration. Using the Marine20 curve and an undetermined ΔR, we generated growth and depositional models to establish an overview of the formation of this lagoon.

萨尔加达湖位于巴西里约热内卢州海岸的南帕拉伊巴河三角洲平原，是世界上为数不多的近代叠层石发育良好的泻湖之一。萨尔加达湖是一个高盐泻湖，形成于非常复杂的环境系统中，在不同的海平面状况和气候变化下受到陆地和海洋的影响。此外，沉积物和叠层石具有异常正的无机 δ 13 C VPDB 值。因此，它已成为多项地质和古环境研究的目标，其中大多数都需要地质年代学技术来确定环境随时间的变化。当使用放射性碳（14 C）测年时，需要考虑环境中14 C来源的一些细节，并相应地进行14 C年龄校准。本文进行了文献调查，以回顾数据处理并完善基于精确校准的环境演化讨论。使用 Marine20 曲线和未确定的 ΔR，我们生成了生长和沉积模型，以概述该泻湖的形成。
