Rift-basins are the shallow effects of lithosphere-scale extensional processes often producing polyphase faulting. Their sedimentary evolution depends on the mutual interplay between tectonics, climate, and eustasy. Estimating the role of each factor is generally a challenging issue. This paper is focused on the tectono-sedimentary evolution of the Neogene Siena-Radicofani Basin, a polyphase structural depression located in the inner Northern Apennines. Since Miocene, this basin developed after prolonged extensional tectonics, first as a bowl-shaped structural depression, later reorganized into a half-graben structure due to the activation of high-angle normal faults in the Zanclean. At that time the basin contained coeval continental and marine settings controlled by the normal faulting that caused the development of local coarse-grained depositional systems. These were investigated to: (i) discriminate between the influences of tectonics and climate on sedimentation patterns, and (ii) provide detailed time constraints on fault activity. The analysed successions were deposited in an interval between 5.08 and 4.52 Ma, when a climate-induced highstand phase occurred throughout the Mediterranean. However, evidence of local relative sea-level drops is registered in the sedimentary record, often associated with increased accommodation space and sediment supply. Such base-level fluctuations are not connected to climate changes, suggesting that the faults generally control sedimentation along the basin margins.

裂谷盆地是岩石圈尺度伸展过程的浅层效应，经常产生多相断层。它们的沉积演化取决于构造，气候和摇头丸之间的相互影响。估计每个因素的作用通常是一个具有挑战性的问题。本文的重点是新近纪锡耶纳-拉迪科法尼盆地的构造-沉积演化，它是位于北亚平宁山脉内部的多相构造凹陷。自中新世以来，该盆地经过长期的伸展构造发展，首先是碗状的构造凹陷，后来由于赞克拉（Zanclean）大角度正断层的活化而重新组织成半岩状结构。当时该盆地包含受正常断层控制的中世纪大陆和海洋环境，而常规断层导致局部粗粒沉积系统的发展。对这些进行了调查，以：（i）区分构造和气候对沉积模式的影响，以及（ii）对断层活动提供详细的时间限制。当整个地中海地区都发生了由气候引起的高峰期时，所分析的演替沉积的时间间隔为5.08至4.52 Ma。但是，沉积记录中记录了局部相对海平面下降的证据，这通常与容纳空间的增加和沉积物的供应有关。这种基本水平的波动与气候变化无关，这表明断层通常控制着盆地边缘的沉积。对这些进行了调查，以：（i）区分构造和气候对沉积模式的影响，以及（ii）对断层活动提供详细的时间限制。当整个地中海地区都发生了由气候引起的高峰期时，所分析的演替沉积的时间间隔为5.08至4.52 Ma。但是，沉积记录中记录了局部相对海平面下降的证据，这通常与容纳空间的增加和沉积物的供应有关。这种基本水平的波动与气候变化无关，这表明断层通常控制着盆地边缘的沉积。对这些进行了调查，以：（i）区分构造和气候对沉积模式的影响，以及（ii）对断层活动提供详细的时间限制。当整个地中海地区都发生了由气候引起的高峰期时，所分析的演替沉积的时间间隔为5.08至4.52 Ma。但是，沉积记录中记录了局部相对海平面下降的证据，这通常与容纳空间的增加和沉积物的供应有关。这种基本水平的波动与气候变化无关，这表明断层通常控制着盆地边缘的沉积。当整个地中海地区都发生了由气候引起的高峰期时，所分析的演替沉积的时间间隔为5.08至4.52 Ma。但是，沉积记录中记录了局部相对海平面下降的证据，这通常与容纳空间的增加和沉积物的供应有关。这种基本水平的波动与气候变化无关，这表明断层通常控制着盆地边缘的沉积。当整个地中海地区都发生了由气候引起的高峰期时，所分析的演替沉积的时间间隔为5.08至4.52 Ma。但是，沉积记录中记录了局部相对海平面下降的证据，这通常与容纳空间的增加和沉积物的供应有关。这种基本水平的波动与气候变化无关，这表明这些断层通常控制着盆地边缘的沉积。
