The complex urban geology of the historic center of Naples is characterized by the emplacement of products from two adjoining volcanic areas that were reworked by alluvial and coastal processes. To expand the geologic knowledge of this densely populated area, multidisciplinary research was carried out on the recently drilled San Marcellino borehole, as part of a larger borehole collection project. Critical revision of 290 previously drilled sequences, and a complete set of tephrostratigraphic, sedimentologic, and paleoecologic data obtained on the San Marcellino stratigraphy, informed a hydrogeological conceptual model of water circulation and paleoenvironmental reconstruction of the city historic center. Both before and after the Neapolitan Yellow Tuff eruption, ca. 15 ka, the landscape was characterized by a marine to transitional paleoenvironment. This signifies a good balance between sea-level rise and volcaniclastic inputs, consisting of both primary and remobilized deposits in an area that is also subject to bradyseismic oscillations. Amongst the primary pyroclastic deposits, the products of an explosive event from Campi Flegrei about 16 ka, with an eastward-directed sustained-column phase, were recognized. Collectively, the multidisciplinary data obtained in this study favor the presence of a double-aquifer conceptual model, characterized by a volcanic and a marine-sedimentary aquifer.

那不勒斯历史中心的城市地质复杂，其特点是将来自两个毗邻火山区的产品进行了冲积，这些产品经过冲积和海岸过程进行了重新加工。为了扩大这个人口稠密地区的地质知识，作为一个更大的钻孔收集项目的一部分，对最近钻探的圣马塞利诺钻孔进行了多学科研究。对290条先前钻探的序列进行了重要修订，并从圣马塞利诺地层学获得了完整的地层，地层学，古生态学数据，为城市历史中心的水循环和古环境重建提供了水文地质概念模型。那不勒斯黄凝灰岩喷发前后，约。15 ka，地貌以海洋为过渡古环境为特征。这标志着海平面上升和火山碎屑输入之间的良好平衡，该输入既包括该地区的主要沉积物也包括迁移沉积物，而该地区也经历了缓震振荡。在主要的火山碎屑沉积中，人们认识到了坎皮·弗莱格里（Campi Flegrei）发生的一次爆炸事件的产物，该事件具有向东的持续柱相。总的来说，这项研究中获得的多学科数据有利于存在以火山岩和海洋沉积含水层为特征的双重含水层概念模型。在主要的火山碎屑沉积中，人们认识到了坎皮·弗莱格里（Campi Flegrei）发生的一次爆炸事件的产物，该事件具有向东的持续柱相。总的来说，这项研究中获得的多学科数据有利于存在以火山岩和海洋沉积含水层为特征的双重含水层概念模型。在主要的火山碎屑沉积中，人们认识到了坎皮·弗莱格里（Campi Flegrei）发生的一次爆炸事件的产物，该事件具有向东的持续柱相。总的来说，这项研究中获得的多学科数据有利于存在以火山岩和海洋沉积含水层为特征的双重含水层概念模型。
