Chronology of the Middle-Upper Pliocene succession in the Strongoli area: constraints on the geological evolution of the Crotone Basin (Southern Italy)

The aim of this study is to reconstruct the evolution of the Strongoli area, a critical sector of the Crotone Basin (Calabria,
Southern Italy), where a thick Middle-Upper Pliocene marine succession is present. The Strongoli succession shows prominent
changes in the sedimentary environment that are partly forced by tectonics. Major tectonostratigraphic events have been recognized
that might correlate with spreading pulses in the back-arc Tyrrhenian Sea. In particular, we demonstrate that a dramatic basinal
collapse at c. 2.3 Ma correlates with the so-called ‘Calabrian transgression’ Auctorum and is close in age to the oceanization of the Marsili Basin.

本研究旨在重建强罗地区（克罗托内盆地，意大利南部）的演化历程，该地区是克罗托内盆地的一个关键区域，其中存在厚重的中新世晚期至上新世早期海相沉积层。强罗沉积层在沉积环境方面表现出显著的变迁，部分变迁受到构造力的驱动。已识别出主要的构造地层事件，这些事件可能与后弧提尔仁尼海扩张脉冲有关。特别是，我们证明了大约在230万年前发生的盆地剧变与所谓的‘卡拉布里亚海侵’Auctorum相吻合，并且与马西里盆地的海洋化过程年龄相近。
