The multidisciplinary analysis of two long sedimentary successions of continental and shallow marine deposits from the Venetian plain (NE Italy) provides new data on the stratigraphic architecture and the landscape evolution of the south-eastern Alpine foreland basin during the last 210–220 ka, with further evidences of a warm temperate phase older than MIS 8.

We present and discuss a detailed multi-proxy data set from these successions (GER1 and CB cores). The results of stratigraphic, palynological and micropalaeontological analyses are cross-interpreted, showing the potentiality of building a composite section of two close continental successions within the same alluvial system, the Brenta megafan, with 15 km distance between cores along a downstream direction. The chronology of the upper part of the cores is supported by radiocarbon dating, showing the presence of Last Glacial Maximum (LGM) and post-LGM fluvial deposits. Lower down, the estimated chronology relies on the tight integration between palynostratigraphy and lithostratigraphy, on the recognition of main unconformities, as well as on the correlation with other regional biostratigraphic records and the Northern Hemisphere/global isotopic record.

The only marine transgression recorded in the studied successions is attributed to the MIS 7.3 and represents the basal tiepoint for the correlation between the two cores. Below the MIS 7.3 transgressive marine surface there is a fluvial succession with weakly-developed palaeosoils and a poor pollen content suggesting cold climate (possibly MIS 8), that lies on top of a thick peat layer showing palynological evidence of a warm temperate climate. The occurrence of well-preserved Pterocarya and Carya pollen in the basal peat level (GER1 core) is compared to that of other pollen sequences in Europe, providing new insights for the chronological framing of the problematic last occurrence of these taxa in the southern alpine area.

Whilst mixed temperate forest persisted throughout MIS 7c-7a, conifers spread during MIS 6. By this time, a glaciofluvial aggradation phase is recorded, highlighting the strong relationship between glacial maxima and alluvial aggradation in the Venetian plain. None of the drilling sites were reached by the Last Interglacial sea transgression. However, the Eemian forest signature is well recorded in CB core, and the following Early to Middle Würm stadial-interstadial sequence is clearly outlined thanks to the joint analysis of the two successions. Broad-leaved thermophilous forests disappeared at the end of the Early Würm and only Pinus and Betula persisted throughout the LGM, during which a chronologically well-constrained glaciofluvial aggradation occurred. The last depositional event corresponds to the post-LGM cut-and-fill of fluvial incised valleys in GER1 core, and to soil evolution and very thin burial by Brenta River fluvial deposits in CB core. The comparison between the results of this study with data of previous deep cores in the distal alluvial plain remarks an increasing long-term subsidence towards Venice area.

对来自威尼斯平原（意大利东北）的大陆和浅海沉积物的两个长沉积演替进行多学科分析，为东南高山前陆盆地在最后210-220 ka期间的地层构造和景观演化提供了新数据。比MIS 8更早的温带阶段的进一步证据。

我们提出并讨论了这些继承的详细多代理数据集（GER1和CB核心）。对地层学，孢粉学和微古生物学分析的结果进行了交叉解释，显示了在同一个冲积系统Brenta巨扇内建立两个紧密陆相演替的复合剖面的潜力，岩心之间沿下游方向有15 km的距离。岩心上部的年代学得到了放射性碳年代学的支持，表明存在最后冰川期（LGM）和LGM后河床沉积。向下，估计的年代顺序取决于古地层学和岩石地层学之间的紧密结合，对主要不整合面的认识，

研究序列中记录的唯一海侵行为归因于MIS 7.3，并代表了两个核心之间相关性的基础联系点。在MIS 7.3海侵海面以下，有一个河流相演替，古土壤发育较弱，花粉含量低，表明气候寒冷（可能是MIS 8），位于厚泥炭层之上，显示了暖温带气候的孢粉学证据。将欧洲基层泥炭层中保存完好的翼龙和山核桃花粉（GER1核心）与欧洲其他花粉序列的发生进行了比较，从而为这些高分类群在南部高山地区最后一次出现问题的时间顺序框架提供了新的见解。 。

尽管混合温带森林在MIS 7c-7a中始终存在，但针叶树在MIS 6中传播。到了这个时候，记录了冰川河流相的凝结阶段，突显了威尼斯平原冰川最大值与冲积作用之间的密切关系。上一次冰河间海侵事件没有一个钻探地点到达。但是，Eemian森林签名在CB核心中有很好的记录，并且通过对两个演替的联合分析，清楚地概述了随后的Würm早期到中期的地缘间断序列。宽叶的嗜热森林在维尔姆早期消失了，只有松树和桦树LGM在整个LGM中持续存在，在此期间发生了时间约束良好的冰川流积。最后一次沉积事件对应于LGM后GER1岩心中河床切谷的填埋，并对应于CB岩心中Brenta河河床沉积物的土壤演化和非常薄的埋藏。这项研究的结果与远冲积平原以前的深部岩心的数据之间的比较表明，对威尼斯地区的长期沉降正在增加。
