Abstract The Messinian Salinity Crisis (MSC) was an extraordinary geological event that affected the whole Mediterranean region, as well as global marine circulation between 5.97 and 5.33 Ma. In the Mediterranean, the crisis was mainly characterized by isolation from the Atlantic Ocean, resulting in a new hydrological budget leading to the accumulation of large amounts of evaporites and large-scale erosion of its margins. The nature of the majority of the evaporites and erosional surfaces is still unknown, thus representing a challenge which forms the subject of debate in the scientific community. The Neogene Mallorca basins (Balearic Islands) are well situated to provide a stratigraphic record which expresses the sequence of events related to the MSC, being especially suitable for testing possible geological models or scenarios. New research on the island of Mallorca provides data about the MSC and Zanclean reflooding in the central part of the Western Mediterranean (Balearic Basin), with obvious repercussions for both academia and industry. The main aim of this study is to describe the features which characterize sedimentation during the Miocene-Pliocene transition on the island of Mallorca, to establish how this stratigraphic record relates to the different proposed MSC scenarios for the whole of the Mediterranean. In this regard, a stratigraphic analysis was carried out on a total of 100 exposures and boreholes corresponding to the Neogene basins of Mallorca. The results indicate that, on the island of Mallorca, the development of the MSC is most consistent with models that represent the main phase of desiccation occurring after the accumulation of marginal evaporites (Primary Lower Gypsum), the Terminal Carbonate Complex and the Lago Mare deposits.

马略卡岛的救世主盐度危机：对西地中海地层情景的新见解

摘要 墨西拿盐度危机（MSC）是一次非同寻常的地质事件，在 5.97 至 5.33 Ma 期间影响了整个地中海地区以及全球海洋环流。在地中海，危机的主要特点是与大西洋隔绝，导致新的水文收支平衡，导致大量蒸发岩聚集和边缘大规模侵蚀。大多数蒸发岩和侵蚀表面的性质仍然未知，因此代表了形成科学界争论主题的挑战。Neogene Mallorca 盆地（巴利阿里群岛）位置优越，可以提供地层记录，表达与 MSC 相关的事件序列，特别适合测试可能的地质模型或情景。对马略卡岛的新研究提供了有关西地中海中部（巴利阿里盆地）的 MSC 和 Zanclean 再洪水的数据，对学术界和工业界都产生了明显的影响。本研究的主要目的是描述马略卡岛中新世-上新世过渡期间沉积特征的特征，以确定该地层记录如何与整个地中海的不同拟议 MSC 情景相关。在这方面，对与马略卡岛新近系盆地相对应的总共 100 个暴露点和钻孔进行了地层分析。结果表明，在马略卡岛上，
