The phenomenon of repeated soil liquefaction, in which the same soil liquefies multiple times during recent earthquakes, has resulted in extensive environmental damage, infrastructure destruction, and human loss. This highlights the need to establish advanced models to assess the liquefaction susceptibility of granular soils upon a sequence of shaking events, an area where current knowledge remains very limited. This paper presents a literature review of laboratory studies on the liquefaction behavior of soils during multiple shaking events. Experimental data from laboratory multi-stage tests, including cyclic triaxial (CTX), cyclic simple shear (CSS), cyclic torsional shear (CTS), and cyclic stacked-ring shear tests (CSRS), are employed and reanalyzed using the critical state soil mechanics (CSSM) framework. It is suggested that liquefaction resistance curves derived from CTS tests can be used to consider the impacts of the initial fabric and state of sandy soils, as well as various prior shear histories, on the reliquefaction response of sands. A suite of models is established for the first time to predict the reliquefaction (short-term) and multiple liquefaction (long-term) resistance of granular soils with different initial fabric and states and with different stress and strain histories upon successive seismic events.

The Semail Ophiolite in Oman has been central to obduction research for over 50 years. Our new study builds on this legacy, introducing 254-km long balanced and restored NE-SW cross-sections that run from the Semail Ophiolite to the Fahud foreland. These sections through Central Oman, resolve geometric inconsistencies, providing a clearer, quantifiable crustal-scale kinematic model from Mid-Cretaceous to present-day. Our findings reveal a ∼ N030° compressional direction from 15 new localities, reconstruct a 235 km minimum length pre-obduction hyperextended Hawasina Basin, and identify the 16–22-km wide Sumeini slope as a crucial low-angle footwall ramp for allochthonous nappes. We have also pinpointed four main detachment levels shaping the Central Oman Mountains: the Semail Ophiolite and Hawasina basal detachments, the Jabal Akhdar flat-ramp-flat thick-skinned thrust, and the Ara Salt detachment. Through stepwise kinematic reconstructions, we defined three key subduction-driven obduction stages from Mid-Cretaceous: 1) Pre-obduction Stage (Albian-Cenomanian boundary to 95.2 Ma) characterized by NE-dipping intra-oceanic subduction and slab rollback; 2) Obduction Stage (∼95.2–80 Ma) depicting the Semail Ophiolite and Hawasina nappes obduction over the Oman margin; and 3) Post-obduction Mountain-building Stage since Campanian times. Finally, we have estimated a convergence rate of 22 mm/yr during the Late Cretaceous (95.2 to 85 Ma), accounting for near half of the total convergence between Arabia and Eurasia. This study provides a powerful new framework for understanding obduction and mountain building, serving as a valuable template for investigating regions where later continental collision has obscured evidence of these processes.

Classical paleoclimate reconstructions rely on a space-for-time substitution approach, but past environmental conditions may extend beyond modern analogs. This introduces biases in reconstructions, known as the edge effect, stemming from no-analog past conditions, statistical limitations, and eco-physiological effects. Quantification and partitioning of the sources of the edge effect remain limited. Here, we examined temperature reconstructions based on branched glycerol dialkyl glycerol tetraethers (brGDGTs) from global modern soils, and quantified the factors contributing to the edge effect. Our analysis shows that climate variables alone are the dominant contributors to the reconstruction bias, accounting for 46%, while soil properties (23%) and topography (13%) represent additional environmental controls. Biotic factors also contribute, with vegetation accounting for 11% and bacterial community structure for 7% of the total bias. We employed a Sparse Identification of Nonlinear Dynamics approach to dynamically simulate brGDGT-based temperature biases. Applying this simulation to loess deposits from the Chinese Loess Plateau, we demonstrate a previous overestimation of Last Glacial Maximum temperatures by 1.2–4.2 °C. These findings advance our understanding of edge effects in both modern and paleo-reconstructions, and highlight the need for caution when using proxies, especially under no-analog conditions.

The middle to late Mississippian period witnessed substantial transformations in global paleogeography, climate, marine environments, and ecosystems. Unraveling the causal relationships among these events necessitates the establishment of a unified chronostratigraphic framework applicable across various regions and depositional environments, a challenge that has yet to be fully addressed. In this study, we present the first comprehensive integration of late Visean to Serpukhovian foraminiferal and conodont biostratigraphy with δ13C stratigraphy from the Youjiang Basin in South China, along with a comparison to corresponding datasets from other regions in the Western Paleotethys. This study performs a detailed and precise correlation between foraminiferal, conodont, and δ13C stratigraphy from South China. Additionally, a synthesis of δ13C profiles and biostratigraphic records from the Paleotethys realm confirms the presence of two critical bioevents near the traditional Visean–Serpukhovian boundary, both within the interval corresponding to the Russian Venevian Substage (in ascending order): the first occurrence of Janischewskina delicata and ‘Millerella’ tortula, followed by the first appearance of Lochriea ziegleri. The younger bioevent is considered here as a rather suitable primary marker for the redefinition of the base of the Serpukhovian Stage, particularly because this level closely aligns with the nadir of a prominent positive δ13C excursion (designated as Vp3). By contrast, the slightly earlier first occurrence of J. delicata and ‘M.’ tortula coincides with the rising limb leading to Vp2 following the preceding negative δ13C excursion (Vn1), providing important auxiliary guides, although their local first occurrences are less consistent compared to those of L. ziegleri. The Visean–Serpukhovian boundary has not been formally defined biostratigraphically due to the scarcity of traditional Tarusian markers in the Chinese sections. However, based on foraminiferal bio- and δ13C chemostratigraphic records from the Vegas de Sotres section (Cantabrian Mountains, northern Spain), the base of the Tarusian can be tentatively positioned just below the nadir of another significant positive δ13C excursion (Sp1).

<div><div>Plant terrestrialization—the early evolution of terrestrial vegetation originating, establishing, and expanding during the Silurian-Carboniferous—was a critical event in the evolution of the terrestrial biosphere that shaped the way to a habitable Earth. Under favorable paleobotanical, paleoclimatic, paleogeographical, and paleotectonic conditions, large quantities of plant remains can accumulate as peat in wetlands, forming a key component of the global carbon cycle, a major terrestrial carbon sink, and eventually coal deposits. However, the direct influence of terrestrialization on coal accumulation and coal quality remains unclear. This review examines the synergistic interplay between the evolutionary characteristics of coal-forming vegetation across the Rhyniophytic, Eophytic and Paleophytic Terrestrialization Phases and global coal accumulation, focusing on coal composition and seam thickness. In the Silurian radiation prelude, plants were mostly aquatic algae and early vascular plants (e.g., <em>Cooksonia, Rhynia</em>) inhabiting near-water environments, with poorly developed vascular tissues and low biomass. No terrestrial coal accumulated. In the Rhyniophytic to early Eophytic Floras, early vascular plants still dominated, but body sizes and biomass increased, and organs including roots and primitive small leaves evolved. Coal-bearing sediments were sporadically distributed along equatorial tropical coastlines and in shallow marine environments, composed predominantly of detrital organic matter derived. In the late Eophytic to early Paleophytic floras, evolution of secondary xylem (wood), arborescence, and concentrated root systems increased biomass, with peat accumulating from higher plants in equatorial tropical coastal plains and forming sporadically mineable humic coals with ∼50% liptinite. The early Paleophytic Flora witnessed the evolution of deep root systems and the seed habit, enabling plants to gradually occupy drier environments. Peat accumulation intensified with humic coals dominated by liptinite (∼70%) widespread in equatorial coastal plains. In the middle Paleophytic Flora, lycopods, sphenopsids, ferns and pteridosperms further developed, and arborescence became more prevalent, with industrially significant humic coals (vitrinite content >40%) accumulating widely in low-latitude tropical and mid-latitude temperate zones. The late Paleophytic Flora witnessed proliferation of existing lineages with <em>Cordaites</em> emerging as dominant coal-forming gymnosperms in lycophyte dominated wetlands. Extensive workable humic coal seams developed across low-latitude tropical and mid-latitude temperate zones.

We investigate the deep crustal structure of the Western and Central Alps based on recent S- and P-wave velocity models and previous seismic images coupled to geological surface information. Key observations of the S-wave velocity model are two deep, crustal low velocity anomalies (a frontal and an inner anomaly) and the termination of the European continental crust below the wedge. Balanced cross-sections show that deep geometries from geophysical constraints are consistent with shallow structures from geological data. In both the Western and Central Alps, an early phase of collision, characterized by distributed shortening throughout the whole orogen, occurred from the onset of collision, at 32 Ma, until c.a. 22 Ma. In the Western Alps, a late phase of shortening, from 22 Ma onwards, is localized on the frontal crustal ramps in the pro-wedge below the External Crystalline Massifs. In the European crust, these collisional structures root in the inner velocity anomaly (middle- to lower-crustal low S-wave velocity zones) interpreted as a thick shear zone acting as a deep, crustal decollement. This velocity anomaly is possibly due to the development of syn-kinematic Alpine metamorphic paragenesis (amphibolite facies) in a deep, ductile decollement. Thus, the 10-Myr time interval (32–22 Ma) for shortening and localization on frontal thrusts in the European crust may reflect the characteristic time of deformation localization within the deep decollement.

Key observations of the S-wave velocity model are two deep, crustal low velocity anomalies (a frontal and an inner anomaly) and the termination of the European continental crust below the wedge. Balanced cross-sections show that deep geometries from geophysical constraints are consistent with shallow structures from geological data.
