The Levant constitutes an important region for assessing linkages between climate and societal changes throughout the course of human history. However, large uncertainties remain in our understanding region's hydroclimate variability under varying boundary conditions. Here we present a new high-resolution, precisely dated speleothem oxygen-carbon isotope Sr/Ca records, spanning last 20 ka from Jeita Cave, northern Levant. Our record reveals higher (lower) precipitation-evaporation (P-E)...

Abstract Dated oxygen and carbon isotopic profiles from a Holocene stalagmite (11.9–1.1 ka) the Jeita cave, Lebanon, are compared to variations in crystallographic habit, diameter growth rate. The show generally high δ 18 O 13 C values during late-glacial period, low early Holocene, again after 5.8 ka. On basis of good correlation between morphological aspect its records, as well response speleothems central northern Israel, we relate drier conditions. Between 6.5 ka an increase values,...

Abstract One of the most common observation in Mediterranean areas is migration contractional deformation and associated slabs through time toward external orogenic areas, with lower plate crustal accretion. The Dinarides orogen Central Europe an optimal place to study such a sequence deformation. Compared other contraction was less overprinted by subsequent extension, while remnant subducted slab observed far position. Understanding deformational evolution hampered reduced availability...

Abstract The process of recrystallization affecting dolomitic successions remains a longstanding enigma in carbonate research. Recrystallization influences the accuracy genetic dolomitization models as well prediction porosity and permeability distribution within reservoirs. We investigate early-formed dolomites Upper Jurassic Arab Formation reservoir (Arabian Platform, United Emirates), where is not easily ascertained based on petrographic O-C-Sr isotope analyses. Conversely, application...

Abstract Recent scientific work has highlighted the presence of an up to 12 km thick Cenozoic siliclastic and carbonate infill in Levant Basin. Since Late Eocene, several regional geodynamic events affecting Afro‐Arabia Eurasia (collision strike slip deformation) induced marginal uplifts. The initiation local long‐lived drainage systems Oligo‐Miocene period (e.g., Lebanon, Arabia Nile) provoked a change depositional pattern along region from carbonate‐dominated mixed clastic‐rich systems....

Sedimentary basins adjacent to plate boundaries contain key tectonic and stratigraphic elements understand how stress is transmitted through plates. The Levant Basin a place of choice study such because it flanks the Fracture System Africa/Anatolia boundary. This paper uses new high-quality 3-D seismic reflection data unravel evolution margin this basin during Cenozoic, period corresponding formation System, part Africa/Arabia Four major groups structures are identified in interpreted...

The Tertiary Piedmont Basin (TPB) in northwest Italy is a wedge-top basin developed during Eocene—Pliocene times the Alps-Apennines tectonic junction. It accommodates, on average, 3 km of clastic sedimentary units with significant lateral facies variations, and several basin-scale unconformities tectonically-controlled. experienced deformation under markedly different regimes, developing long-lived kilometric structures that affected both successions, underlying metamorphic rocks...

Collisional orogens are characterized by complex contractional and extensional deformation, which significantly impact fluid migration mineralization. These processes crucial for understanding subsurface flow dynamics, with implications geothermal energy, hydrogen production, CO2 storage. The Dinarides orogen in southeastern Europe, formed during the closure of Neotethys Ocean subsequent Adria-Europe collision, provides an excellent natural laboratory to investigate fluid-flow fluid-rock...

The Asal-Ghoubbet Rift is a less-than-one-million-year-old area characterized by both magmatic and tectonic activity. It underlain very thin crust exhibits exceptionally high temperatures at reachable depths, making it highly favorable for geothermal energy development. However, despite the temperatures, exploitation in this region faces significant challenges, mostly related to sustainable access fluids, including generally low permeability, flow rates, saline fluids. Some of identified...

Sedimentary reservoir rocks generally have complex and heterogeneous pore networks that are related to the original depositional rock texture subsequent diagenetic alterations. Such alterations in part controlled by mineralogy sedimentological facies, compaction history, involved fluids (and rock/fluid interactions), flow history physico-chemical conditions. During evolution (paragenesis), cycles of alternating dissolution (porosity enhancement) precipitation destruction) caused changes...

Abstract The Kesrouane Formation, which is characterized by pervasive dolomitization, has a stratigraphic thickness that exceeds 1000 m. It part of broad carbonate platform deposited in the Levant region and represents 60% Lebanese Jurassic rocks. Two genetically distinct dolostones are recognized within this unit: (1) fine‐to‐medium crystalline non‐planar grey dolostone; (2) coarse‐crystalline planar beige dolostone. former stratabound Early age ( 87 Sr/ 86 Sr = 0·707455).

Abstract Layer-bound normal faults commonly form polygonal with fine-grained sediments early in their burial history. When subject to anisotropic stress conditions, these will be preferentially oriented. In this study we investigate how grow, evolve and interact within regional-scale layer-bound fault systems characterized by parallel faults. The intention is understand the geometry growth of applying qualitative quantitative analysis techniques a 3D seismic reflection dataset from Levant...
