ABSTRACT Bagnoli-Coroglio is a Site of National Interest (SNI) facing the Pozzuoli Bay that has been the place of an industrial activity for more than a century (1854-1985). The modern coastal geology of this area results from the recent evolution of an antecedent volcanic landscape that originated after a caldera collapse following the eruption of Neapolitan Yellow Tuff (NYT) of Campi Flegrei (15 ka). After the NYT eruption, a shallow marine depression formed within the caldera collapse area that underwent progressive filling-up, due to volcaniclastic sediment input from the caldera borders, within a semi-enclosed source-to-sink system. The integrated interpretation of the Digital Terrain Model (DTM) of the Bagnoli-Coroglio area and the high resolution reflection seismic profiles acquired off the Pozzuoli Bay suggests that the present-day coastal plain of Bagnoli-Fuorigrotta and conterminous continental shelf represent the latest infilling phase of the annular depression (caldera ‘collar’) between the structural border of the NYT caldera and the inner caldera resurgent dome. The stratigraphic architecture and morpho-bathymetry of the Bagnoli inner shelf provide a record of the complex interplay between eustatic sea level changes, volcano-tectonic (ground/seafloor) deformation, and supply of volcaniclastic sediments, with associated coastline shifts over the last millennia.

Bagnoli-Coroglio 海岸带和大陆架的地质框架，波佐利（那不勒斯）湾

摘要 Bagnoli-Coroglio 是一个面向国家利益的遗址 (SNI)，面向波佐利湾，一个多世纪以来（1854-1985 年）一直是工业活动场所。该地区的现代海岸地质源于近期火山景观的演变，该火山景观起源于 Campi Flegrei (15 ka) 的那不勒斯黄色凝灰岩 (NYT) 喷发后的火山口坍塌。NYT 喷发后，由于火山碎屑沉积物从火山口边界输入，在半封闭的源汇系统内，在火山口坍塌区域内形成了一个浅海洼地，该洼地经历了逐渐填充。Bagnoli-Coroglio 地区的数字地形模型 (DTM) 和波佐利湾的高分辨率反射地震剖面的综合解释表明，今天的 Bagnoli-Fuorigrotta 沿海平原和大陆架代表了最新的填充阶段NYT 火山口的结构边界和内部火山口复活圆顶之间的环形凹陷（火山口“领”）。Bagnoli 内陆架的地层结构和形态水深测量记录了海平面变化、火山-构造（地面/海底）变形和火山碎屑沉积物供应之间复杂的相互作用，以及过去几千年相关的海岸线变化。
