Sand injection complexes are increasingly recognised as a common shallow-crustal process, comprising millimetre- to decametre-scale, close to bedding-concordant sills and strongly bedding-discordant dykes, as well as intrusions with less regular geometry. These features can act as basin-scale fluid migration conduits, hydrocarbon reservoirs and possible sites for CO₂ sequestration. This paper presents 2D point-spread function (PSF) seismic modelling of a digital outcrop model containing a wide range of intrusion geometries, including thin, complex and interconnected features. The results provide insights into the seismic response of subseismic (unresolved) geological features and enable evaluation of the effects of illumination, lateral resolution, dominant frequency and noise on seismic imaging. Multiple densely spaced thin intrusions generate interference as a function of wavelength, producing complex seismic patterns caused by the dense spacing and cross-cutting geometry of intrusions. The seismic patterns show little resemblance to the geometry of the intrusions. Increases in dominant frequency improve the resolution and interpretation of large intrusions from seismic data and preferentially intensify some seismic characteristics, sometimes creating bedding-like, sub-horizontal features that do not exist in the outcrop data. This ambiguity caused by enhancement of sub-horizontal intrusions relative to sub-vertical intrusions can lead to misinterpretation of sandstone presence and distribution. Individual intrusions with a thickness of 1 m may be detected under favourable conditions but are not directly resolvable in seismic data and increased dominant frequency does not necessarily result in improved geological interpretation. High-angle dykes (&gt; 45^o) display linear zones with amplitude dimming, which are attributed to their cross-cutting character, thus facilitating their interpretation. Seismic amplitudes from host strata interact with those of intrusions, diminishing the clarity of the seismic response of intrusions. Limited illumination reduces the accuracy of interpretation. The addition of noise increases the complexity of intrusion-related seismic responses, both enhancing and reducing amplitudes associated with intrusions, specifically in intervals with complex intrusion networks.</p>","PeriodicalId":8712,"journal":{"name":"Basin Research","volume":"37 5","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/bre.70062","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140685","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}

This study integrates high-resolution 3D seismic data, core analyses, and wireline logs within a sequence stratigraphic framework to characterise the depositional environment within the targeted Miocene interval. Seismic attributes such as RMS amplitude and spectral decomposition are used to define the three-dimensional architecture of the geobodies and evaluate their potential for CO₂ storage by comprehending reservoir distribution, heterogeneity, and connectivity. The reservoir consists of two unconsolidated sand units, informally termed the lower and upper sand units, separated by a mudstone interval. The lower sand unit represents a basin floor fan emplaced by gravity flows during the falling stage systems tract, while the upper unit comprises unconfined gravity flow deposits associated with the lowstand systems tract. The reservoir sands of the Lille John Member are predominantly localised in the southeastern portion of the Central Graben at depths suitable for storing supercritical CO₂. Theoretical P50 storage capacity is estimated at approximately 1108 million tonnes for the lower sand unit and 51 million tonnes for the upper unit. Heterogeneities such as silt beds, mudstones, and carbonate concretions may act as flow baffles, enhancing storage efficiency through plume dispersion, residual trapping, CO₂ dissolution, and geochemical interactions.

The presence of hard mudstone thus impacts the ability to predict hydrocarbon presence directly from seismic data during exploration. To establish the mechanism of ‘hardening’ to better predict the presence of variable mudstone characteristics, we examine three cored wells from the Beryl Embayment. Well logs and core were examined to characterise the structure, petrology, petrophysical properties and spatial distribution of both hard and soft mudstones. The results indicate that mudstone hardening is most likely associated with mechanical compaction and efficient dewatering of mudstones into the sand injection complex. This process is enhanced where sand injection complexes transect primary overpressure zones, that promote dewatering from basal overpressured mudstone into the injection network. This study highlights that seismic response needs careful investigation in the context of the complexity of the injectite complex along with variable mudstone attributes.

This method has been successfully applied to basins with carbonate strata, whereas its application in basins composed of clastic strata is limited. This study focused on calcite cements in the upper Permian to Triassic terrestrial clastic strata in the Junggar Basin, northwestern China. Petrological, elemental geochemical and clumped isotopic analyses were conducted in combination with vitrinite reflectance analysis and forward thermal modelling. The studied strata contain multiple generations of calcite cement: early- and late-stage calcite. Relatively high δ¹³C values (−6.2‰ to −0.8‰), high δ¹⁸O values (−15.9‰ to −11.3‰) and low clumped isotopic temperatures (T(∆₄₇): 31°C–43°C) suggest that the Permian and Triassic early-stage calcite precipitated during the penecontemporaneous stage. Considering the high MnO contents (2.22%~14.05%), extremely low δ¹³C values (−60.5‰ to −38.4‰) and high T(∆₄₇) values (95°C–132°C), the late-stage calcite in the Triassic rocks is explained as the product of the oxidation of hydrocarbons by high-valence Mn/Fe oxides during mesodiagenesis. The high δ¹³C values (−10.2‰ to −10.7‰) indicate that the late-stage calcite in the Permian rocks is the product of the decarboxylation of organic acids. Constrained by the T(∆₄₇) values of the early- and late-stage calcite and forward kinetic modelling, the maximum temperature of the upper Permian is confined to 150°C during the Late Jurassic. The thermal gradient of the study area exhibited an overall decreasing trend from 40°C·km⁻¹ in the late Permian to 22°C·km⁻¹ in the Cenozoic. The results are 2°C–4°C per km higher than those of previous works based on vitrinite reflectance and apatite fission track annealing.

We focus on the fluvial deposits of the Montllobat and Castissent Formations, deposited during the early Pyrenean orogeny.

This intensification in hydrological regime implies a clear climate driver and is compounded with a switch in interpreted fluvial planform morphology from anastomosing to a dominantly braided planform at the onset of the Castissent interval and a 1.4-fold increase in channel slope. We suggest the transient hydrological signature of the Castissent Formation was driven by Ypresian hyperthermal events superimposed on a levelling-off in the global cooling trend at the end of the EECO and an increase in tectonic uplift rates at c. 50 Ma.

Despite extensive thermochronological research, the basin's exhumation history, magnitude and driving processes remain a subject of scientific debate. We present a large new apatite (U-Th-Sm)/He (AHe) dataset from a densely sampled deep exploration borehole extending beyond the actual Molasse basin fill into the underlying sedimentary sequence to provide more robust constraints on the exhumation history. AHe ages of over 100 grains range between 4 and 30 Ma in the upper 500 m and between 3 and 80 Ma below 1300 m, respectively. This is counterintuitive as, given the partial resetting of the shallow data, total reset would be expected at depths exceeding approximately 600 m. To arrive at a single consistent thermal history, we use a forward thermochronological modelling approach that allows us to test the influence of different provenance histories and distinguish between cooling phases associated with changes in heat flow vs. changes in exhumation. We find that a total of approximately 1100 m of Neogene exhumation, already starting at around 11 Ma, reconciles all available data. Exhumation continued throughout the Late Miocene but was initially not accompanied by significant cooling, suggesting a compensation by gradual increase of heat flow. At around 5 Ma, heat flow rises sharply towards the anomalously high present-day values of 120 mW m⁻². We argue that this discrepancy between the onset of exhumation and the onset of cooling may be responsible for previously differing estimates for the exhumation history of the basin.

The structures produced by the upper Ordovician salt are thought to have a much wider distribution in the Kosyu–Rogov Trough and the adjacent Chernyshev Swell than was previously believed. The sedimentary cover of the Kosyu–Rogov Trough is decoupled along the salt layer, resulting in the long-distance transfer of contraction in the post-salt deposits. Based on an integrated interpretation of subsurface data, including 2D and 3D seismic surveys, two types of salt structures are recognised: (1) salt pillows and (2) squeezed diapirs. The salt pillows are distributed in the mildly disturbed central part of the Kosyu–Rogov Trough above the layer-parallel flat of the salt detachment. The squeezed diapirs are clustered within the external part of the study area in the highly disturbed Chernyshev Swell, where the salt layer is passing into basin margin carbonate equivalents. The squeezing of the massive salt diapirs of the Chernyshev Swell has produced large, salt-detached backthrusts in the external part of the Kosyu–Rogov Trough. The horizontal displacement of the backthrust can reach 15 km. Stratigraphic thinning over diapirs and angular unconformities indicate that the initiation of the salt tectonics preceded the onset of the Uralian collision shortening in the late Artinskian. Salt diapirism episodically influenced the facies distribution in the post-salt deposits, predetermining the location of carbonate banks, reefs, oolitic shoals and karstified areas. The large thickness of the sedimentary cover has resulted in early hydrocarbon migration, peaking before the Uralian shortening. This explains why previous exploration projects targeting thrust-related traps that postdated the main migration were largely unsuccessful. It is proposed that traps associated with long-lived salt structures, which were able to receive a hydrocarbon charge during the peak of hydrocarbon migration, are of primary exploration interest.</p>\u0000 </div>","PeriodicalId":8712,"journal":{"name":"Basin Research","volume":"37 5","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144891576","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}

However, how magmatism, deformation and exhumation interact to control the evolution of the basin–range system remains unclear. This study applies multisystem thermochronometry to elucidate the links between exhumation and post-collisional magmatism, sedimentary burial, thrusting, and deformation at the boundary of the STS–Kuqa basin. Our results reveal that the eastern Kuqa basin experienced rapid exhumation during Permian–early Triassic times, coinciding with volcanic eruptions (ca. 293–288 Ma and ca. 262–254 Ma) and accelerated tectonic subsidence in the western region. The early Permian exhumation was driven by post-collisional continental extension, whereas the late Permian–early Triassic exhumation was associated with regional-scale transpressive strike–slip faults. From the late Triassic to Early Cretaceous, the Kuqa basin experienced continuous burial reheating, corresponding to continuous denudation in the STS during that period. Subsequently, long-term slow denudation in the STS region continued until the early Cenozoic. During the Oligocene–early Miocene, southward thrusting along the North Tarim Fault resulted in the growth and denudation of the STS, coupled with sedimentary burial reheating in the Kuqa basin. Then, deformation continued towards the Tarim basin and intensified since the late Miocene (ca. 5 Ma). The late Cenozoic deformation and exhumation were synchronous with the reactivation of preexisting faults in the STS, and exhibited a progressive westward increase, which can be linked to the clockwise rotation of the Tarim block during the India–Asia collision.</p>\u0000 </div>","PeriodicalId":8712,"journal":{"name":"Basin Research","volume":"37 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144843625","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}
