The Last Interglacial (LIG) was characterised by a global mean temperature ∼1 °C warmer than the pre-industrial, a pronounced Arctic warming and an elevated sea level. Exploring the nature of LIG environmental changes in local contexts can improve understanding of regional responses to a warmer background state. However, a lack of high-resolution p...

In the lacustrine succession F4‐F5 of the Fucino Basin, central Italy, 20 visible tephra layers were identified in the time interval 250–315 ka (Marine Isotope Stages 8–9). Fifteen of them contained suitable material to explore their volcanic sources. Among these tephra some well‐known eruptions and eruptive sequences of the Roman and Roccamonfina...

In the first millennia of the Holocene, human communities in the Fertile Crescent experienced drastic cultural and technological transformations that modified social and human-environments interactions, ultimately leading to the rise of complex societies. The potential influence of climate on this “Neolithic Revolution” has long been debated. Here...

Thirty‐two tephra layers were identified in the time‐interval 313–366 ka (Marine Isotope Stages 9–10) of the Quaternary lacustrine succession of the Fucino Basin, central Italy. Twenty‐seven of these tephra layers yielded suitable geochemical material to explore their volcanic origins. Investigations also included the acquisition of geochemical dat...

The Fucino Basin, central Italy, with its long and continuous history of Quaternary sediment accumulation, is one of the richest Mediterranean Middle Pleistocene tephra records. Here, we present a new detailed investigation of tephra layers (tephras) of the 250–170 thousand years before present (ka) interval, corresponding to the entire Marine Isot...

At the beginning of Holocene, the Fertile Crescent (FC)-and particularly the Kurdistan Region of Iraq (KRI)-was the scenario of several fundamental cultural events such as the origin of agriculture, the beginning of urbanization, and the formation of the first state entities. The role played by climate and environmental changes on these cultural pr...

A full review of the 79 CE Plinian eruption of Vesuvius is presented through a multidisciplinary approach, exploiting the integration of historical, stratigraphic, sedimentological, petrological, geophysical, paleoclimatic, and modelling studies dedicated to this famous and devastating natural event. All studies have critically been reviewed and in...

In the first millennia of the Holocene, human communities in the Fertile Crescent (FC) experienced drastic economic, cultural and technological transformations that modified social and human-environments interactions and ultimately led to the rise of complex societies. The potential influence of climate on this “Neolithic Revolution” has long been...

Accurately reconstructing the scale and timing of dynamic processes, such as Middle-Late Pleistocene explosive volcanism and rapid climatice change, requires rigorous and independent chronological constraints. In this framework, the study of distal volcanic ash layers, or tephra, transported and deposited over wide regions during explosive volcanic...

Rationale The suitability of organic matter (OM) removal pre‐treatments in isotopic studies of lacustrine carbonates is currently under debate. Naturally occurring OM seems to have a negligible effect on the bulk isotopic composition of carbonates compared with changes induced by pre‐treatments. This study provides further insights into the possibl...

Here we present the first tephrostratigraphic, palaeomagnetic, and multiproxy data from a new ~98 m-deep sediment core retrieved from the Fucino Basin, central Italy, spanning the last ~430 kyr. Palae-oenvironmental proxy data (Ca-XRF, gamma ray and magnetic susceptibility) show a cyclical variability related to interglacial-glacial cycles since th...

RATIONALE: The suitability of organic matter (OM) removal pre-treatments in isotopic studies of lacustrine carbonates is currently under debate. Naturally occurring OM seems to have a negligible effect on the bulk isotopic composition of carbonates compared to changes induced by pre-treatments. This study provides further insights into the possible...

Proxy records of past climate change spanning beyond the radiocarbon range commonly derive their chronologies from orbital tuning strategies, thus bounding our spatio-temporal reconstructions to a priori assumptions that can not be directly tested. Here we present a tephrochronologically constrained framework of past environmental and climatic chan...

The sedimentary succession deposited in Fucino palaeo-lake potentially records the environmental history of the Central Mediterranean Region continuously since the early Pleistocene and up to recent historical times. Fucino palaeo-lake sediments are interbedded with numerous volcanic ash layers which allow the reconstruction a robust and independen...

We present the first integrated tephrochronological study (major and trace elemental glass composition, Sr and Nd isotope analyses, and 40Ar/39Ar dating) for the last one tenth (∼82 m) of the ∼900 m-thick Quaternary lacustrine succession of the Fucino Basin, the largest and probably only Central Apennine intermountain tectonic depression that hosts...

Here we present the first integrated tephrochronological study (major and trace elements glass composition, Sr and Nd isotope analyses and 40 Ar/ 39 Ar dating) for the uppermost ~82 m of the ~900 m-thick Quaternary lacustrine succession of the Fucino Basin. Located in a favorable position with respect to the prevailing westerlies, and in a good ran...

Much of our knowledge and understanding of the spatiotemporal variability and mechanisms underlying Quaternary climatic changes rely on regionally representative, high-sensitivity and chronologically well constrained proxy records. Quaternary lacustrine successions from Central Apennine tectonic basins in central Italy, have been shown to fulfill t...

A 82 m-long borehole was retrieved from the Fucino Basin, the largest intermountain tectonic depression of the Central Apennine. It hosts a ca. 900 m-thick and continuous succession of fine-grained lacustrine sediments, interbedded with several fall-out deposits from the pery-Tyrrhenian Quaternary volcanic centers, and potentially spanning back to...

An 82m long sedimentary succession was retrieved from the Fucino Basin, the largest intermountain tectonic depression of the central Apennines. The basin hosts a succession of fine-grained lacustrine sediments (ca. 900 m-thick) possibly continuously spanning the last 2 Ma. A preliminary tephrostratigraphy study allows us to ascribe the drilled 82m...
