Nonetheless, these basement faults likely affect the dynamics and the kinematics of the rifting, especially during the early stages of extension. Our study focusses on the Porcupine Basin, offshore west of Ireland, an aborted rift propagator that experienced a 220 Myr-long geological evolution with several rifting episodes. Detailed seismic analysis, integrated with exploration well data, illustrates the regional complexity of the structural patterns across the basin, with faults running subparallel or transverse to its axis. This tectonic framework controlled the northward migration of the crustal stretching during the Late Jurassic, followed by crustal thinning during the Early Cretaceous. Pre-existing, orogenic-derived structures bound crustal terranes that control deformation pulses when rifted apart. This suggests structural barriers that either slowed the northward rifting migration during the Oxfordian, Kimmeridgian and Tithonian when crosscutting through the Variscan and Caledonian fold-and-thrust belts, or stopped the rifting by the end of the Barremian when it encountered Caledonian and Grenvillian crystalline basements. We propose that this structural inheritance led to the formation of a typical rift propagator of continental nature, and that the Porcupine Basin constitutes a remarkable example of a termination of rifting processes in a well-formed oceanic rift system.</p>\u0000 </div>","PeriodicalId":8712,"journal":{"name":"Basin Research","volume":"37 4","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144681397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study describes the results of 3-dimensional geological mapping of a large (~14 × 9 km), well-exposed Early Cretaceous dolerite sill in Central Spitsbergen, Svalbard, Arctic Norway, using a combination of digital outcrop modelling and field mapping.

Sill segments emplaced at the boundary between two formations, which mark a strong lithological and rheological boundary, are straight and concordant. Conversely, segments emplaced within a more homogeneous formation exhibit more irregular, locally discordant shapes. The sill segments emplaced at distinct stratigraphic levels are connected by steeply dipping steps, which formed through dilatant shearing between the tips of the sill segments. The preferred NW-SE orientation of the steps and the thinning of the sill towards the SE suggests a propagation direction of the magma towards the SE.

The detailed correlations and strontium isotope ages constrain the geologic ages of Units II, III and IV of the Site C0020 succession as Eocene to Early Miocene. Cores and resistivity image logs show that Units II, III and IV consist of five facies associations, indicating bay, estuarine to fluvial, delta and muddy slope systems and eleven depositional sequences. Plot mapping of these facies associations and seismic facies indicates the drastic changes of the forearc basin setting through four tectonic phases from Eocene to Miocene. During Phase 1 (Eocene to Early Oligocene: Unit IV), the bay-to-estuarine system was dominant within a restricted forearc basin by a subaerially uplifted trench slope break. Phase 2 (Early to Late Oligocene: Unit III and the lowermost Unit II) was characterised by further uplift and erosion of the trench slope break, which formed three Oligocene unconformities: Ounc1, Ounc2 and Ounc3. During Phase 3 (Late Oligocene to Early Miocene: Unit II), a large-scale subsidence of the trench slope break started, possibly related to the onset of tectonic erosion of the subducting plate, and the forearc basin became an open-marine setting with a prograding delta system. After the formation of Miocene unconformity (Munc), Phase 4 (Middle Miocene-: Unit I) caused the cessation of the delta system, and the forearc basin became a muddy deep-water slope system, possibly resulting from the continent-derived sediment supply decrease due to the backarc opening of the Sea of Japan.</p>","PeriodicalId":8712,"journal":{"name":"Basin Research","volume":"37 4","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/bre.70042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144537232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A natural example of multi-stage fault zone evolution with different generations of deformation elements and mode of silica cementation was investigated using combined structural, burial, micropetrographic, geochemical and geochronological analyses in a sandstone predating the main rifting phase. Deformation mechanisms progressively evolved from proto-cataclasis, through advanced cataclasis connected with inhomogeneous silica cementation, to siliceous fluid-enhanced slip along discrete fault planes or vein formation; all of these processes are well correlated with burial and volcanic phases. The established relationships allowed reconstruction of the evolutionary steps within the fault zones as the initially porous sediment was structurally and diagenetically hardened and then softened, and the geometry of the fault system changed during rifting. The age of silica-associated fracture systems (syn-tectonic silica cementation) is constrained by early type deformation bands (having the same pattern as silica-associated fractures) occurring in the ~15.3 Ma pyroclastic rocks bordering the sandstone. Silica precipitation can be related primarily to structurally controlled fluid pulses and rapid cooling as fluids pass through the propagating syn-rift fractures in an initially good siliciclastic aquifer. Such large-scale hydrothermal fluid migration, resulting in tens of km² siliceous cementation, was facilitated by the onset of volcanic activity. The accompanying general increase in fluid pressure may have led to the permutation of the maximum and the intermediate principal stress axes. As a result, the early syn-rift extension switched to a transtension during the main syn-rift phase. Meanwhile, vertical axis rotations also contributed to the change in the apparent stress field, resulting in the development of a fault pattern analogous to an oblique rift.

However, the transfer of sediment from the source to the sink and the factors controlling it are still poorly understood. We focus on a small catchment coupled with its offshore deep-sea fan: the Sithas system (Gulf of Corinth, Greece). We restore the volume of sediment eroded in the catchment using geomorphic constraints; quantify the volume of sediment deposited in the offshore basin, after revising the age model; and calculate erosional fluxes using the BQART model. This allows for the comparison of the reconstructed fluxes of sediment eroded and deposited since 800 ka across the entire source-to-sink system. For the Sithas coupled catchment-deep-sea fan system, we show an increase in sedimentary fluxes both in erosion and deposition since 800 ka and particularly since 400 ka, where cyclic variations of ~120 kyr are recorded in erosion and deposition compartments. We suggest that the overall increase in flux results from a change in the catchment size due to the tectonic evolution of the region. The record of cyclic variations from 400 kyr in fluxes matches with the maturity of the system and with the intensification of glacial cycles and tectonic constraints migration. We also suggest that the discrepancy between erosion and deposition reflects a temporary storage between source and sink areas, probably along the coast. This has changed since 30 ka, introducing the last phase of evolution characterised by phased source and sink dynamics, suggesting a lack of temporary storage and a connection between river outlet and submarine canyon head.

The Putumayo Basin is a broken foreland basin in western Amazonia at ~1°–3° N, where the Florencia, Macarena, and El Melón-Vaupes basement highs have compartmentalised discrete depocentres during basin development.

The Pyrenees Mountains represent an ideal location to test the accuracy of source-to-sink predictive methods, as the well-studied mountainous sources and sediment sinks, including the Aquitaine, Jaca, and Ebro basins, collectively serve as a reference for evaluating the accuracy of predictive approaches. This study uses a paleo-digital elevation model (pDEM) of Bartonian age (ca. 40 Ma) to reconstruct catchments for the Pyrenees. When coupled with published paleoclimatic constraints, the BQART equation is used to predict sediment fluxes into each sedimentary basin. Predicted sediment volumes are compared against volumes calculated from bedrock exhumation rates across the Pyrenees, and against published rock volumes preserved within Pyrenean sedimentary basins. Consistency between total sediment volumes predicted by the BQART model and for exhumation rates is within a factor of 1.5, and within a factor of 2 when sediment volumes are partitioned by sedimentary basin, indicating the pDEM is able to generate realistic, first-order estimates of sediment flux. An uncertainty analysis showed that the runoff category contributes the greatest uncertainty to the BQART equation, highlighting the requirement for paleoclimate and drainage constraints on this parameter. When BQART and exhumation-derived volumes are compared against preserved sediment volumes in the Aquitaine and Jaca Basins, sediments are undercounted by an order of magnitude. This is a result of the limited scope of volume quantification, as depocentres are defined by modern geography only, and from the postdepositional erosion of sediment in an active orogenic setting. Sediment volumes in the better-preserved Ebro Basin were predicted within a factor of 1.35 and 2.5.

The Hanö Bay and Bornholm Basin contain a sand-rich mounded depositional feature proximal to the STZ.
