Climate change and tectonic uplift are the dominant forcing mechanisms responsible for the formation of long and narrow terraced landforms in a variety of geomorphic settings; and marine terraces are largely used to reconstruct the Quaternary glacial and interglacial climates. Along the Mediterranean coast, a considerable number of popular scientific articles have acknowledged a range of marine terraces in the form of low-relief surfaces resulting from the combined effects of tectonic uplift and eustatic sea-level fluctuations, as relevant geomorphological indicators of past sea-level high-stands. With the exception of a few recent studies on the significance of submarine depositional terraces (SDT), submerged terraced landforms have been less investigated. By integrating different marine and terrestrial datasets, our work brings together and re-examines numerous terraced landforms that typify the Cilento Promontory and its offshore region. In this area, studies since the 1960s have allowed the recognition of well-defined Middle to Upper Pleistocene marine terraces on land, while only a few studies have investigated the occurrences of late Pleistocene SDT. Furthermore, to date, no studies have consistently integrated findings. For our work, we correlated major evidence of emerged and submarine terraced landforms in order to support an improved understanding of the tectono-geomorphological evolution of the Cilento Promontory and to further clarify the geomorphological significance of submerged terraces.

奇伦托海角(东南第勒尼安河边缘)的岸上和岸上梯田地貌及其作为海平面变化第四纪记录的意义

气候变化和构造隆升是在各种地貌背景下形成长而窄的梯田地貌的主要强迫机制。海洋梯田主要用于重建第四纪的冰川和冰川间气候。沿着地中海沿岸,许多流行的科学论文都承认,构造隆起和海平面涨落的共同作用是低浮雕表面形式的一系列海洋阶地,是过去海域的相关地貌指标。高水平的看台。除了近期对海底沉积阶地(SDT)的重要性的一些研究之外,对淹没式梯田地貌的研究较少。通过整合不同的海洋和陆地数据集,我们的工作汇集并重新审视了奇伦托海角及其近海地区的众多梯田地貌。在该地区,自1960年代以来的研究已允许识别陆地上定义明确的中上更新世海洋阶地,而只有少数研究调查了晚更新世SDT的发生。此外,迄今为止,还没有研究持续整合研究结果。对于我们的工作,我们将出现和海底阶地地貌的主要证据关联起来,以支持对奇伦托海角构造-地貌演化的更好理解,并进一步阐明淹没阶地的地貌意义。自1960年代以来的研究已经允许识别陆地上定义明确的中上新世海洋阶地,而只有少数研究调查了晚更新世SDT的发生。此外,迄今为止,还没有研究持续整合研究结果。对于我们的工作,我们将出现和海底阶地地貌的主要证据关联起来,以支持对奇伦托海角构造-地貌演化的更好理解,并进一步阐明淹没阶地的地貌意义。自1960年代以来的研究已经允许识别陆地上定义明确的中上新世海洋阶地,而只有少数研究调查了晚更新世SDT的发生。此外,迄今为止,还没有研究持续整合研究结果。对于我们的工作,我们将出现和海底阶地地貌的主要证据关联起来,以支持对奇伦托海角构造-地貌演化的更好理解,并进一步阐明淹没阶地的地貌意义。
