Located on the northern coast of Santa Maria Island (Azores Archipelago, central North Atlantic), the Lagoinhas section preserves a carbonate buildup correlated with Marine Isotope Substage (MIS) 5e, the warmest interval of the Last Interglacial. The buildup is formed mainly by crustose coralline algae (CCA) identified as Spongites sp., and some subordinate crusts of Lithophyllum sp. and Neogoniolithon sp., as well as cf. Titanoderma sp. Extant CCA buildups are not recorded in the archipelago. Herein, we describe in detail the morphological and taphonomical features of the Lagoinhas CCA buildup and interpret the environment in which it grew. Additionally, this buildup is compared with another of similar age, exposed in the Prainha-Praia do Calhau section on the island's opposite southern coast. The hydrodynamic regime appears to play a crucial role in the development of Azorean CCA buildups during the MIS 5e.

Lagoinhas 部分位于圣玛丽亚岛北部海岸（亚速尔群岛，北大西洋中部），保留了与海洋同位素亚级 (MIS) 5e 相关的碳酸盐堆积，这是末次间冰期最温暖的间隔。累积主要形成由壳状珊瑚藻（CCA）鉴定为Spongites属，和一些从属结壳Lithophyllum藻。和Neogoniolithon sp.，以及参见。钛皮sp. 群岛中没有记录现存的 CCA 积累。在这里，我们详细描述了 Lagoinhas CCA 堆积的形态和埋藏特征，并解释了它生长的环境。此外，将这种堆积物与另一个年龄相近的堆积物进行比较，该堆积物暴露在该岛对面南部海岸的 Prainha-Praia do Calhau 部分。在 MIS 5e 期间，水动力状态似乎在 Azorean CCA 堆积的发展中起着至关重要的作用。
